Variables through funtions and inludes..

[nielskg]

Hi,

How can I set variables in functions and includes throughout a large index.php, and have that variable available at the very end of that index.php?

Thanx,

I gues you mean globals?

globals are evil, never create globals inside functions, always let the function return a value, and make that value a global after you got it from the function.

A forum, a FAQ, what else do you need?

actually...

I have a index.php in which 2 other php files are included. in the 1st one is a function, in which a variable is created but not sent back by the function (and this may not happen too). but I need this variable in the 2nd included php file...

how it this done?

I would follow vincent advice about transmitting var as argument, not as globals; that way for instance :

index.php :

<?
// beginning of index.php

include ('php1.php');
include ('php2.php');
...
$myvar = function_php1 ();
// (BTW, it works even if $myvar is null)
...
$result = function_php2 ($myvar);
// Now do what I want with $result
...

// end of index.php
?>
