$string = "[18,23,24,8]";
preg_match_all('/(\d+)/', $string, $m);
var_dump($m);

This will return to you array of matches.

Array ( 
[0] => Array ( [0] => 18 [1] => 23 [2] => 24 [3] => 8 ) 
[1] => Array ( [0] => 18 [1] => 23 [2] => 24 [3] => 8 ) 
)

In you case those will be identical, you can use any$m[0], or$m[1] - doesn't matter.
