why not try this:

<?php
    $str = " [100][200][300][400] ";
    $str = explode("][", trim($str, "[] "));
    print_r($str);
    exit;

This is better solution than regex if you know that the characters you want to split on are not going to change.

This code maybe can help

$str = "[100][200][300][400]";
$str = explode("][",trim($str,'\[\]'));

Results in:

Array( [0] => 100 [1] => 200 [2] => 300 [3] => 400 )

Use brackets to choose what part of the match you want to return.

preg_match_all('/\[(.*?)\]/', $string , $matches)
