replace preg_replace bbcode to html

Question

help, im trying to convert bbcode to html code , and i keep getting this error

the bbcode is [url=link][attach]1[/attach][/url]

SCREAM: Error suppression ignored for( ! ) Warning: preg_replace(): Unknown modifier '/'

        $content = $getThread['message'];
        $bbUrl = '/\[url=(http|https|ftp)://{1}([a-zA-Z0-9/%@?:#&+._=-]*)\](.*?)\[/url\]/gixsm';
        $htmlUrl = '<a href="{$1}://{$2}" target="_blank">{$3}</a>';
        $atable = $thread->get_atable($tid);
        $content = preg_replace($bbUrl, $htmlUrl, $content);

after the url done, will convert the [attach]1[/attach] again by using

$bbAttachment = 'etc...';
$htmlAttachment = 'etc...';
$content = preg_replace($bbAttachment, $htmlAttachment , $content);

Is this the correct way to do?

Appreciate for helping.

You need to escape foreslashes / with backslashes when using a foreslash as the pattern delimiter so they read \/. — Cobra_Fast

You have an error in your Regex. You need proper escaping for '/' character.

change this

 $bbUrl = '/\[url=(http|https|ftp)://{1}([a-zA-Z0-9/%@?:#&+._=-]*)\](.*?)\[/url\]/gixsm';

to this

 $bbUrl = '/\[url=(http|https|ftp):\/\/([a-zA-Z0-9\/%@?:#&+._=-]+)\](.+?)\[\/url\]/gixsm';

You should also change * to + because I assume you don't want to parse urls that may be empty.

Better, i think, would be to pick a different delimiter. Past a certain point it's just easier.
