I have two types of bbcode: [Attachment]1234[/Attachment] [attach=full]1234[/attach]

$message = 'this is message with attach [attach=full]1234[/attach]

I want to remove everything in the string and use:

(preg_match_all('/\[ATTACH((.*?)\](.+?)\[\/ATTACH\]/i', $message, $out, PREG_SET_ORDER))

if (preg_match_all('/\[ATTACH((.*?)\](.+?)\[\/ATTACH\]/i', $message, $out, PREG_SET_ORDER))
{   
    for ($i=0;$i<count($out);$i++)
    {
        $replace_src[] = $out[$i][0];
        $replace_str[] = $out[$i][1];
        $newMessage = str_ireplace($replace_src, $replace_str, $message);
    }
}

This code deletes [attach][/attach], but does not delete [attach=full][/attach] =full exists in the message.
