[SOLVED] Need example on bb code replacing

[Lautarox]

I'm not really very familiarized with preg_replace and preg_match, I want to know how to use preg_replace to replace like and keep the information between, thanks.

A simple example of converting [ b ], [ i ], [ url=http://www.somesite.com ] to their respective html tags, using preg_replace():

 

<?php
function code_to_html($bbcode){
     $bbcode = htmlentities($bbcode); //convert all html tags to entities to prevent security problems (XSS)
     $searchFor = array('/\[b\](.*?)\[\/b\]/is', '/\[i\](.*?)\[\/i\]/is', '/\[url\=(.*?)\](.*?)\[\/url\]/is'); //the array to search for [ b ], [ i ] and [ url= ] codes
     $replaceWith = array('<b>$1</b>', '<i>$1</i>', '<a href="$1">$2</a>'); //the array to replace bbcodes with html tags
     $html = preg_replace($searchFor, $replaceWith, $bbcode);
     return $html;
}
//then you can call the function
$string = "[b]phpfreaks[/b] has a [i]very[/i] nice [url=http://www.phpfreaks.com/forums]forum[/url]";
echo code_to_html($string);
?>

 

That should give you the idea of using preg_replace() to replace bbcodes to html. The same idea involves any type of code you want to have, just add it in the $searchFor array.
