How Could I Go About Splitting This String Properly?

[Magestickown]

Hello! I made a function to split an IRC message into its: prefix, command, arguments and trailing data.

It works, mostly, except if I add a string that I'm exploding into the trailing data, it will attempt to explode that, instead of the first instance.

Like this:

 

 public function parse_message($str) {
$array = explode(' ', $str);
$username = substr($array[0], 1);
$username = explode('!', $username);
$username = isset($username[0]) ? $username[0] : '';
$command = isset($array[1]) ? $array[1] : '';
$args = '';
$count = count($array);
for($i = 2; $i < $count; $i++)
$args .= $array[$i] . ' ';
$args = explode(' :', $args);
$trailing = isset($args[1]) ? $args[1] : '';
$args = isset($args[0]) ? $args[0] : '';
//:orpheus!1844a5bd@23n.np3.hq2haj.IP PRIVMSG #balls :wah
return array('username' => $username, 'command' => $command, 'args' => $args, 'trail' => $trailing);
}
//:orpheus!1844a5bd@23n.np3.hq2haj.IP PRIVMSG #balls :!eval $this->chat("QUIT :Goodbye.");
//"QUIT :Goodbye" makes it only split up to there.

It should get everything after #balls :, which it does, but if I add an extra " :", it will only get the first index of the array.

 

Also, if someone could maybe find a better way to do this, that'd be great

There is a better way to do this, and it's called Regular Expressions. You can learn everything you need to know about this on regular-expressions.info.

Haha yeah... I understand regex, but only the basics.

Either way, I got it working great now Thanks anyway.

               $args .= $arguments[$i] . ' ';
           $trailing_data = stripos($str, ' :');
           $trailing_data = trim(substr($str, $trailing_data + 2));
           return array('username' => $username, 'command' => $command, 'trail' => $trailing_data, 'args' => $args);
       }
