Bbcode parsing problem

[lpa]

I use this function for BBcode parsing:

function bbcode ($message) {
$search = array(
'@\[(?i)b\](.*?)\[/(?i)b\]@si',
'@\[(?i)i\](.*?)\[/(?i)i\]@si',
'@\[(?i)u\](.*?)\[/(?i)u\]@si',
'@\[color=rgb(.*?)\](.*?)\[\/color\]@si',
'@\[quote=](.*?)\[\/quote\]@si',
'@\[li](.*?)\[\/li\]@si',
'@\[ul](.*?)\[\/ul\]@si',
);

$replace = array(
'<b>\\1</b>',
'<i>\\1</i>',
'<u>\\1</u>',
'<span style=\"color:rgb\\1\">\\2</span>',
'<span class=\"quote">\\1</span>',
'<li>\\1</li>',
'<ul>\\1</ul>',
);
return preg_replace($search , $replace, $message);
}

In most cases it works ok, but not always.

For example:

[color=rgb(102, 0, 102)]H[color=rgb(204, 0, 0)]e[/color]llo[/color]

The result is:

<span style="color:rgb(102, 0, 102)">H[color=rgb(204, 0, 0)]e</span>llo[/color]

As you can see, only the first [color=...][/color] has been converted to html. The second stays as it is. Any ideas?

Nested things like that are a pain in the butt with regular expressions. You might be able to solve it with recursive patterns, but frankly that stuff always makes my head swim. 😉 You might find it simpler in the long run to either use the BBCode extension, or the PEAR::HTML_BBCodeParser package.
