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;
}
