Codice PHP:
<?php
$string1="Simulator    422962/453000        391049/453000        453000/453000            6474/737100";
$string2="    216254/1148";
if (preg_match("/.*\d*.\d*.*\d*.\d*.*\d*.\d*.(\d*).(\d*).*/",$string1,$matches)) {
    $a1=$matches[1];
    $a2=$matches[2];
}

if (preg_match("/.*(\d*).(\d*).*/",$string2,$matches)) {
    $b1=$matches[1]-$matches[2];
}
?>
non funziona..
