im having a problem with my bbcode, im adding a [ php ] [ /php ] tags in it along with highlight_string. it highlights fine, but i have on my forums htmlspecialchars so when it puts the info in the db it changes < to < etc, and when u view the info in the broser it switches back. but with the highlight_string, it doesnt change < back to <

here is my function for the highlight:

function highlight_php($matches) { 

	$php = "<strong>PHP Code:</strong><div style=\"margin:0px 10px; padding:5px; border:1px dotted #FFFFFF; width:90%\">"; 
	$php .= highlight_string($matches[0], true); 
	$php .= '</div>'; 
$php = str_replace("<", '<', $php);
	$php = str_replace("<br />", '', $php); 
	$php = preg_replace("@(\[php\]|\[/php\])@si", "", $php); 
	return $php; 
	
}

i tried to str_replace the < back to < but it wouldnt work.

also i have this in my bbcode function:

$post = preg_replace_callback("@\[php\](.*?)\[\/php\]@is", 'highlight_php', $post);

any help would be great.

thanks,
venomsnake

edit: i think its the htmlspecialchars, i tried $php .= highlight_string(htmlspecialchars('<?php ?>'), true); and it did the same thing

try using htmlspecialchars_decode right after you pull it out of the databse and before you use it for anything

What do you mean you try changing < into <, it's like saying i'm trying to change an apple into itself.

$php = str_replace("<", '<', $php);

That's pointless, you're chaging "<" into itself right there. You can also simplify the removal of the php BBcode tags by doing the following:

$php = preg_replace('@\[(/|)php\]@si', '', $php);

Now, if you're having problems getting &lt; to change to <, that would be a problem. As it stands right now, i'm completely lost on what the problem is.

lol rc69.

Just a side note, for anyone else who is trying venomsnake's soloution, you should note it's a PHP5 specific function.

You can however improvise and recreate the function yourself. Details are on php.net comments.
