Gee Wiz finding the vocab to express the question can be pretty tricky, but hopefully you can tell me what's wrong with referencing a variable in a function in order to change it.
Example:
<?php
$a = 5;
$something = 5;
function changeIt($it){
global $a;
$it = $it * $a;
};
changeIt($something);
echo $something;
?>
This returns 5, so the global variable $something hasn't been redefined.
You need to pass $it
by reference, and also call changeIt
:
<?php
function changeIt(&$it){
global $a;
$it = $it * $a;
}
$a = 5;
$something = 5;
changeIt($something);
?>
