Transfer variabele outside function

[Marco J.L.]

Hello,

how can I transfer a variable from a function to the part after the
function?

thnx,

Marco J.L.
<?php

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

Function func_xxxxx() {
$var = "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';
}
?>

Not doable. PHP doesn't expose API functions through which you can
manipulate the variable space of the parent scope.

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("be fore", "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("be fore", "after", $foo);
return $bar;
}

What's the "global" statment, if not exactly this? "Parent scope" could mean
various things, but the OP posted a function call from the top-level scope -
this means he can use global to change that variable.

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

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

If the "parent scope" were another function then yes, you'd be out of luck;
you should pass a reference to the function to the inner function (you probably
should anyway even when coming from the global scope...).

How about this?

$var = 'before';
$var = after($var);
echo $var;

function after($s) {
return 'after';
}

I wasn't terribly clear in my post. What I meant was manipulating variables
in the parent scope irregardless of whether it's global or not. Basically,
what extract() and compact() are able to do.
