PHP Tut 2 - Minus-Zero - 06-29-2010
Ok its Minus again with php tut 2! Today will be learning all about variable!
Lets begin!
Code:
<html>
<head></head>
<body>
Hmm...Whats your favorite Site and what is your favorite thing about it?
<br />
<?php
//define your variables(remember this is a comment)!!!
$site = 'Exploitnation.org';
$aka = 'ExN';
$rsn = 'Community';
echo "Well its URL is $site . But people just call it $aka ! My favorite thing is the $rsn ...... "
?>
</body>
</html>Now to explain!
$site = 'Exploitnation.org';
$site
This is basically what you write to call for the variable... or whatever you would say! So its what i wrote
in echo so that it would print Exploitnation.org
'Exploitnation.org';
This is what will print or be used when you call for the variable.... So basically it what the processor
converts the $site into!
Well nothing more to explain on that! Now lets move onto other ways to write variables!
Code:
<?php
$num1 = '100';
$answer = $num1 + 10;
echo " Hey what is 100+10? It is $answer ";
?>Ok well here you can see i used a variable to define another variable! Omg im not jesus calm down thats just PHP at work...
All you have to do is define a variable, then you can use that define variable to define another!
Lets move onto this... it l assigns three variables the same value simultaneously! Now i know you think im jesus!
Code:
<?php
$side1 = $side2 = $side3 = 100;
echo " Hey what are the lengths of this triangle? Umm are they $side1 $side2 and $side3 ? ";
?>As you can see it defined $side1 $side2 and $side3 as 100!!!!!
Which means you can have variables all equal the same thing!
Ok well thats all for now! Hope it helped

I have had people say it is easy, you're the first to say it's hard.
Although, I apologize for you having trouble.
