Hi TD hello electra u going to the show? what show new orleans :) Oh..the Convention...no..you? *** TimeWalker sets mode: +o TDavid we can't make this one ... but we'll be at vegas in January thanks tw *** Chazz has joined #netsurprise 04¤WB 14(Chazz14) 04WB¤ 14- Nice to see u back boss man! *** TimeWalker changes topic to 'WEBMASTERS ONLY!!! Welcome TO the TDAVID SHOW ' *** Retrieving #netsurprise info... *** Sassy has joined #netsurprise hi :) hi sassy I have no time to do anything but work even if I could get time off from my offline job...I am going to be swamped hey ZoiNk *** Retrieving #netsurprise info... How are you i am here for a little wile intill i have to go to work hehehehehe yikes ... how about "PHP Course #3: All about arrays" Instead, tw hehe Well I have to get back to my job....have piles of stuff to do before 4...have a good chat. lol that might work better lol bye bye Electra *** Electra has quit IRC (QUIT: User exited) bound to scare them away hehe *** TimeWalker changes topic to 'WEBMASTERS ONLY!!! Welcome the Tdavid Show covering PHP Course #3: All about arrays' ya i dunno thats a good thing or not lol hehe soooo long hehehehehe ok quizz lol ?#1 yes today there will be a pop quiz hehe what is an array ruh ro hehehehehe *** Compdoctor has joined #netsurprise *** TimeWalker changes topic to 'WEBMASTERS ONLY!!! Welcome It's School time Todays lesson is PHP Course #3: All about arrays' hi Compdoctor ? # 2 can it hold strings hey lol @ TimeWalker how r u hon? Hi comp the person who scores the highest walks away with a free script :) hey floppy speakin of scripts i need to talk to u bout 1 sometime TDavid ;) YaHooooooo !!!!!!! lets start the Quizz * Sassy thinks Chazz is a freak some1 told him test a web site to see if its resolved so whats he do? types in "hi world LOL :) " w/o the "" lol kewl sassy :) lol hey TDavid quick question... u goin to cyber net expo? nopers, going to vegas in January :( that stinks maybe we'll go to both lol we pretty much only go to shows in vegas ... but we may go to sharkysr's deal in chicago we love vegas :)) ya thats where cyber net expo is in november thats y i asked ;) when is school td? now? in 10 minutes by my watch anyway this is not live right nope, not live, it's memorex :) my cable died :((((((((((((((( Sorry was ordering supplies Where you staying in Vegas TD ok i gotta run and make lunch for Chazz b4 he goes to work TD i'll keep an eye on your room so that u dont have to be in 2 places at once we usually stay at MGM or fitzgeralds, but we don't have those plans yet that will be my tuesday job :) we just have our airline tickets hehe ok I'l be at the Circus i like the circus circus :) me too the kids do too I like the vip treatment did I miss school again nope, it starts in 6 minutes :) ok cool is it live?

*** Compdoctor is now known as CompDoc-Recording wrong answer ZoiNk sorry *** TimeWalker sets mode: +vvv Chazz CompDoc-Recording floppy *** TimeWalker sets mode: +v Sassy *** Retrieving #netsurprise info... *** TDavid sets mode: +m can somebody leave and come back really quick, testing somethign here hehe yer watch is 4 mins early but who cares *** Sassy has left #netsurprise *** Sassy has joined #netsurprise Welcome Sassy to the tech chat .. this is a moderated instructional chat so please private timewalker to get voice so you can ask questions and take the PHP quiz! *** TDavid sets mode: +v Sassy thank you :) thx hon np got your message :) *** CompDoc-Recording has quit IRC (Connection reset by peer) im using the official doKK clock hehe we'll wait for compdoc to return... poor guy keeps gettin that 2day ok i m gonna go make lunch bbiab just before we start how far back can php read header info? i don't think i really understand the question how far back? ok it can read stuff like browser, etc and with java you can read current session history can php? in php4 you can do sessions yes never mind I'll ask later when it's not school time hehe it is still a state language, not a stateLESS language however because it is server side so you still need to employ some technique in addition to the php to maintain state got my comment above backwards hehe it's K :) php is a stateLESS language ... you need to employ other means to make it state flash is state, java is state, javascript is state shockwave is state i'm actually glad you asked that question because it is important to understand that early on that is the flaw with any cgi scripting language perl/php/asp is all stateless php4 has come some way in making things better with session support but still if you want to track people all around the site and maintain state you need to use cookies or some other type of means hidden forms work, but any time the surfer can view the source of the hidden input forms or query string your program is vulnerable to some degree like I had to resort to java for screen resolution JS yup i want to talk about precedence for a minute ... there is precedence in mathematics and in programming i posted a response to willyB the other day with the order of precedence *** Bestat has joined #netsurprise 12,0 Welcome Bestat to the tech chat .. this is a moderated instructional chat so please private TimeWalker to get voice so you can ask questions and take the PHP quiz! HIGHEST precedence: (){ } ~ ! ++ - - $ & * / % + - < > <= >= == != LOWEST precedence (paused to avoid flood) i used this example for him $total = 4 + 2 / 2; // result is 5 if you look you'll see that division takes "precedence" over addition *** Bestat has quit IRC (QUIT: User exited) well what if we wanted 4+2 = 6 / 2 ? notice the use of parenthesis in the hierarchy? parenthesis have the HIGHEST precedence we'd use something like this: (4+2) yeah (4+2)/2 = 3 *** Wolfes-woman has joined #netsurprise 12,0 Welcome Wolfes-woman to the tech chat .. this is a moderated instructional chat so please private TimeWalker to get voice so you can ask questions and take the PHP quiz! why this may seem of little consequence now, it does make a difference when you start performing mathematical computations in your scripts math on $holders *** breeze has joined #netsurprise could you explain modular operators *** Wolfe has joined #netsurprise well lots of math is done on things like say coming up with ratios for clickthrus and things global ratios, etc IE:$i % $j 2 opps do we have to pm tw to ask a ? no *** TimeWalker sets mode: +v Wolfe bitwise operators are very useful in C but rarely used in PHP, is that what you are talking about floppy? I was starting to feel left out in that example $i=12 and $j=5 *** breeze has quit IRC (QUIT: User exited) well modulars return the remainder of a division ?? with the % now you're getting too mathematical on me, floppy lol *** sharkysr has joined #netsurprise hehe i see your point, there may be times you need to use the remainder *** JP_HardcoreBox has joined #netsurprise * TimeWalker thinks td has a glitch in his script here are the various operators and their functionality 1. . = concatenate *** TimeWalker sets mode: +v sharkysr 2. $ = reference a variable 3. & reference variable storage 4. -> reference a class method or property (OOP) floppy thinks the live show aut to be like this this is real helpfull 5. => Set argument default or assign array element index 6. @ suppress function errors 7. Tertiary Conditional Expression knowing what these are at this point is really all you need to know, knowing when to use these things we will deal with as they come up some of these you might not even need to use or want to could you explain the tertiary conditional expression not familuar with that term tw, i changed the onjoin message to be in private so it wouldn't be in the logs :) What is the & used for TD, is it in MySql? not it is used to pass information into a function, sharkysr er no, that was ok basically you can pass a condition to a function ahh K td tertiary conditional expression is really just a shortcut, floppy *** msbrownie has quit IRC (QUIT: User exited) could you exp[lain nesting variables with the double $$ the logs for these classes are accessable by clicking from scriptschool.com if anyone should miss these is that used to store a variable with in a variable ? here is a use for the ternary operator if($mynumber > 1) { $myname = 'TDavid'; } else { $myname='TimeWalker'; } that same expression can be shortened using the ternary operator $myname='TimeWalker' . ($mynumber > 1 ? "myname" : "myname"); ah got ya stick with if/else it's a lot simpler hehe can we ask any ? about php unless you have a need to shorten up your code considerably you use tricks like that *** ZoiNk has quit IRC (QUIT: User exited) $myname='TimeWalker' . ($mynumber > 1 ? "mynumber" : "mynumber"); // this is correct line when are we going to get into enviromental variables such as Doucment_root ect Course #8 covers header and environmental variables ah ok :) yes you can ask questions, but if you stay with what we covered so far it will be more beneficial i think * TimeWalker thinks we should have a course a day did i miss a question from anybody? When are we going to cover exploding a variable, if you don't mind me asking we can cover that right now, since I showed you with the date() thing how to avoid multiple function calls did you see that code? $string = date("l,|jS|F, Y.");$date_array = explode("|", $string);print("$date_array[0] the $date_array[1] day of $date_array[2]"); Yea, I saw it there, just hadn't had the time to study exactly how it works yet So you can use anything there, or just the pipe? basically we are putting a delimiter inside a string to separate the contents, then we are exploding the contents of that string by using that same delimiter you can use anything, but i would stay away from common things like commas, periods, dashes, etc can you explain a concat operator So if we just use the pipe, we will be safe. even exploding by newlines can be tricky no, not necessarily, some sponsors have scripts where they are using pipes in the sponsor codes the pipe is SUPPOSED to be a delimiter we can use without having that happen, but some programmers are sloppy Would you use the same technique when writing to a file, using the| to delimit records/fields, so you can explode them when you read it back? a concatenation operator, explain it how, floppy? it concatenates lol adds two strings together ok yes, sharkysr, i would use pipes in most cases, there are exceptions but then again there are exceptions to all of programming to avoid confusion i try to show you guys the norm and not the abnorm and gals too, btw :) good idea TD...hahaha now as for the arrays, does everyone understand what they are and what they do? it seems from the code posted that most of you do :) Did you ever get to critique the advanced lessons TD? arrays are just big storage tanks ... variables are like small singular ones like maybe a gas pump or something TD ? how far would you go or how many tables would you make for msql before it gets complicates nope i haven't stopped by the advanced lessons yet msql or MYsql? hehe i don't do much msql, to be honest, mysql is better :) Mysql well floppy that is somewhat of an open-ended question that i'd ask you to reask me in week 14 after we've covered mySQL a bit. That is similar to the question the guy asked at the tech board how many hits can i do a day with a ... {insert hardware here} so many variables involved there really is no simple answer * floppy just wondering cannot help playing with diffrent aspects of it quirosity gets me ya know ;) i've seen 100 table mysql setups that were confusing and 10,000 table ones that weren't Good answer TD, probably depends on how they are layed out. let's say you have 1000 members and each member has 3 tables of their own that are essentially identical ... now you have 3000 tables but really they all are the same basic type of information rather than one huge gargantuan table with everybody's info lumped into it as you can probably guess with mySQL or any database the smaller the pool of information you work with, the better off you usually are be easire to add tables that way or values ect but working with 10,000 small tables is much less efficient than working with 100 larger ones and retriev info What you would have is a single table with member name and number in it that would tie to individual tables for each member so again, it is a tricky question and not easily answered ok ;) thanks TD well yes, the ideal database never repeats information and is interconnected relationally I love those big words... IE. http:// <--- we all know that starts with a url so why even store in a file or database at all use the script to append that to the information you can't do http://www. though because some sites are just ips but you'd be suprised how many databases store 'http://' in it ... over and over and over again *** Conepuppy has joined #netsurprise Hmm Hi cone 10,000 'http://' add up when you really only need to append on the fly pup!! :) plus anything you append from the script will be quicker than retrieving using I/O *** TimeWalker sets mode: +v Conepuppy why is that? disk access is what slows everything down is their a max on number of characters for a table like say name (first_name varchar(20) or can it be (50) if we had no disk access to worry about, imagine how fast things would be If you have to retrieve a record anyway, is the size going to make a difference? yes, there are limits hey TD! absolutely, sharkysr let me give you an example i was recently working on a database of 10,000 records ... the password field was set to 75 characters you ever seen a 75 digit password? or the need for one? no point made ;)) so basically there was 65 characters x 10,000 records ouch I can see your point in that case, but when you are talking about an additional 7 bytes on a record, will you see the difference? got ya ;) guys like pup will see the CPU flutter if a lot of hits happen on a setup like that hehe haha it isn't the 7 bytes, sharkysr ... you got to remember that web is based on traffic ... you start multiplying 7 bytes by 100k hits a day now it starts adding up That is true. Something I need to keep reminding myself about. you can always make things bigger, but it is more difficult to make things smaller there is a great function known as "ALTER" you can alter any character field to be bigger but if you alter it to be smaller you start truncating fields and can run into trouble sometimes That is within the MySQL, right? let's say you had a field with a built in delimiter 'size-name' <-- now if you change the field to 4 digits you just ruined the delimiter and your script would not function right the delimiter being the dash in this case arent you better off to use varing character for larger fields and char for know foelds such a age or sex m/f *** Conepuppy is now known as coneOnphone * floppy well thats all the ? I have hehe head spinning now lol char() uses less memory than VARCHAR() because it is a fixed field no matter what. So if you know the size of the field like say a password field use that. It may also be a little faster in the way the index moves around right thank you alright, who's ready for the quiz hehe noit yet head spinning lol lol, floppy is it multiple choice?? lol thats good ok fire away question 1. a variable can contain multiple items separated by commas? True or Fals fales question 1. a variable can contain multiple items separated by commas? True or False false :) false a variable only contains one item floppy? an array can contain multiples phone brb move on ill catch up nice way to avoid the Q floppy....haha nod sharky well you miss i count that as wrong :) you got a 50/50 chance here hehe quiz delay explain they are all true fals btw :) damn whats up with the 'e' incidentally hehe and they are trick questions too :) floppy ... going once ok back #! false wolfe you got a guess? #2? $variable = 'item1,item2,item3,item4'; the answer is TRUE, a variable CAN contain multiple items separated by a comma for what purpose? *** coneOnphone has quit IRC (QUIT: User exited) ok let move on * TimeWalker screams you can explode the contents into an array what was the question ??? one sec phone again brb he's right that cause you can read a comma delimited file into one variable split or explode it into an array I shoulda fucking known that since I'm doing it You are only suppose to ask questions about things you've already taught us TD i have taught you that :) it's on the boards as an example, yes? hehe Or wasn't I paying attention the date thing, plus we reviewed it today :) ok damm it was multiple items separated by a pipe :) ok, next question ... * TimeWalker slaps timewalker around WAKE UP yea, ok, you are right... Question 2. Arrays can hold strings variables and arrays. TRUE or FALSE true true true multi-dimensional array how many ? are their 10 you are all correct :) batting 500 not bad :) :) We'll be batting 667 in a minute lol td's advanced programming question :) Question 3. print and echo can both accept formatted strings? TRUE or FALSE true true no I think only print false *** LaughingEyes has joined #netsurprise actually the answer is TRUE. A string that is ALREADY formatted can be output using print() or echo() that was a wording trick.. no fair ok next :) have to go pick up kids soon Sounds like a trick question to me lol@TW echo can't accept formatting.. print can sounds like td has done this quizz before *** LaughingEyes has quit IRC (QUIT: User exited) We knew what we were talking about didn't we TW? $string = sprintf("%2.f", $string); echo($string); // try it :) yea SS he did a word play
