For capitals, you will need to add an extra variable:
PHP Code:
$lower = strtolower($input);
And then set $lower as the input, so your new code would be:
PHP Code:
function bbcode($input){
//lower the string to non-capitals
$lower = strtolower($input);
$pattern[0] = "/\[b\](.*)\[\/b\]/";
$pattern[1] = "/\[url\=(.*)\](.*)\[\/url\]/";
$replace[0] = "<strong>$1</strong>";
$replace[1] = "<a href=\"$1\">$2</a>";
// your new subject is the string all lower case
$bbcoded = preg_replace($pattern, $replace, $lower);
echo $bbcoded;
}
codeBB("[b]hello![/b] [url=http://www.php.net/]PHP[/url]");
However, this will mean that you will have no capitals at all in your string. One moment while I work this out please. Of course you could just put in new rules for uppercase but I am fairly sure there is something to cut time.
Code:
[ b]bold[/b] not bold [ b]bold again[/b]
I would have to say that the best way to tackle this is create a seperate match for [ b] and [/b], for example:
PHP Code:
$pattern[0] = "/\[b\]/";
$pattern[1] = "/\[\/b\]/";
$replace[0] = "<strong>";
$replace[1] = "</strong>";
preg_replace($pattern, $replace, $input);
