Returns nothing. (BBC Parsing) (Easy but please help)

[Hiccups]

Heres the code Im using. I do not understand why it doesn't return anything. What I mean is it doesn't echo varo's value. The page is blank.

<?php
$varo="mdddono";
function bbcode_format($varo) {
$search = array(
'/[b](.?)[\/b]/is',

'/[i](.?)[\/i]/is',

'/[u](.?)[\/u]/is',
'/[img](.?)[\/img]/is',
'/[url](.?)[\/url]/is',
'/[url\=(.?)](.*?)[\/url]/is'
);

$replace = array(
	'<strong>$1</strong>',
	'<em>$1</em>',
	'<u>$1</u>',
	'<img src="$1" />',
	'<a href="$1">$1</a>',
	'<a href="$1">$2</a>'
	);

$var = preg_replace ($search, $replace, $varo);


return $varo;
    echo $varo;

}
?>

return() ends the function so echo is never called, you generally don't want to echo inside a function.

You never used the function either. This works fine.

<?php

$varo="mdddono";

bbcode_format($varo);

function bbcode_format($var) {
    $search = array(
        '/\[b\](.*?)\[\/b\]/is',
        '/\[i\](.*?)\[\/i\]/is',
        '/\[u\](.*?)\[\/u\]/is',
        '/\[img\](.*?)\[\/img\]/is',
        '/\[url\](.*?)\[\/url\]/is',
        '/\[url\=(.*?)\](.*?)\[\/url\]/is'
        );

$replace = array(
    '<strong>$1</strong>',
    '<em>$1</em>',
    '<u>$1</u>',
    '<img src="$1" />',
    '<a href="$1">$1</a>',
    '<a href="$1">$2</a>'
    );

$var = preg_replace ($search, $replace, $var);

echo $var;
return $var;

}

?>
