Random split

Splits an array into random length parts.

function RandomSplit($min, $max, $str){
    $a = array();

    while ($str != ''){
        $p = rand($min, $max);
        $p = ($p > strlen($str)) ? strlen($str) : $p;

        $buffer = substr($str, 0, $p);
        $str = substr($str, $p, strlen($str)-$p);

        $a[] = $buffer;
    }
    return $a;
}

/*
** Example:
*/

$test_string = 'This is a example to test the RandomSplit function.';

print_r(RandomSplit(1, 7, $test_string));

/*
Outputs something like this
(Array items are 1 to 7 characters long):
