bbcode font-size

[jman11]

how you retrieve the font size from bbcode for example:

[size={number}]{text}[/size]

i want to use preg_replace to turn that into <span style="font-size: {number};">{text}</span>
this will be with a whole array, where the 'pre-replaced' tag is the key in an array, and the value i want to replace it with is the value like this:

$root = array(
"/blah/" => "cool"
);

thanks :D

$find = array(key($root), current($root));
$replace = array("{number}","{text}");
$content = "[size={number}]{text}[/size]";

echo str_replace($find, $replace, $content);

[JohnCanyon]

you could also use those values as tokens.. and learn from vincevincevince's one line template engine post.

ok yeh im using that except using the grouped variable thins like "$1" and "$2", is there anyone to do math and divide one by 2? when i try like "content...".$1/2."more content" it like says unexpected number, this is in one of the arrays to do preg_replace by the way.
