quick php question

Hey,

I'm teaching myself PHP, & I have a simple question.

When PHP coders code a page like index.php?var=1234, what is the name of the function to do that?

I don't know what the funtion name is, so I can't look it up in the manual. :-P

Thanks.

index.php is the filename
var is a variable you pass to the script and
1234 is the value of that variable.

in the php code you can do anything with this variable

<?php
if ($var){
echo $var;
}
?>

will show
1234.

 

Thank you!!!

 

That code depends on register globals being on, which the default has been off for some time...

you should use something like

$var = $_GET['var'];

in new code

 

yea if your starting new its best to write code for register globals being off.

 

There is also $_REQUEST[] which includes COOKIEs, POST, and GET.
But doing ?var=1234 this is called a GET request.
