Hey sorry that i keep posting so many questions but i just have one more how would you create a BB code to like show a youtube video like this

[video]You tube video link[/video]

 

any help would be appriciated thanks in advance

Pretty simple function as long as you match the $find indices with the $replace it should work a treat. I'll look implementing a caching feature in the future.

<?php
function textToBB($string)
{
// Warning: YOU MUST htmlspecialchar this raw user input.
$string    =    htmlspecialchars($string,ENT_QUOTES,'utf-8');

// Format nicely
$string    =    nl2br($string);

// Patterns
$find    =    array(
	'/\[video\](.*?)\[\/video\]/is',
	'/:\)/'
);

// Replace with
$replace    =    array(
	'<object width="480" height="385"><param name="movie" value="http://www.youtube.com/v/$1&hl=en_US&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/$1&hl=en_US&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="480" height="385"></embed></object>',
	'<img src="images/happy.gif" alt="happy" />'
);

// Join them up
$string    =    preg_replace($find, $replace, $string);  

// return parsed code
return $string;
}


$string    =    'lots of text, etc etc look at my Youtube video: 

[video]BIduOvEoVeQ[/video]';

echo textToBB($string);
