Need help with reg exp

[Hamlets666]

So there is a long text.
For example:
[i]Lol [xc] pop [lo][/i]

I want to get in array txt which is between [ and ]
Like $arr[0] would be xc and $arr[1] would be lo.

I hope you understand  ;)

[code]
<?php
  $blah = "Lol [xc] pop [lo]";
  preg_match_all("/\[(.*?)\]/i", $blah, $matches);
  $arr = $matches[1];
?>
[/code]
