<?php

$var="before function";
func_xxxxx();
echo $var;

function func_xxxxx() {
global $var;
$var = "after function";
}

?>

or

<?php

$var="before function";
$var = func_xxxxx();
echo $var;

function func_xxxxx() {
return "after function";
}

?>

have you read any documentation whatsoever?
http://www.php.net/manual/en/language.functions.php

and don't crosspost!

Use the global statement.

<?php
$var = 'before function';
func_xxxxx();
echo $var;

function func_xxxxx() {
global $var;
$var = 'after function';
}
?>

I believe you can do this if you pass the variable by reference:

$var = "before function";
myFunc($var);
echo $var;

function myFunc(\$foo)  {
$foo = str_replace("before", "after", $foo);
}


But a more elegant way is to return the variable back to the program:

$var = "before function";
$var = myFunc($var);
echo $var;

function myFunc($foo)  {
// Do some manipulation on $foo and set it to $bar
$bar = str_replace("before", "after", $foo);
return $bar;
}
