For those that want to kill everything matching a certain pattern (ala killall in for linux), try something like this. Note that this is a good idea to do something like this for cross platform compatilibity, instead of executing killall, because killall for other UNIXes does just that, kills EVERYTHING. :)
function killall($match) {
if($match=='') return 'no pattern specified';
$match = escapeshellarg($match);
exec("ps x|grep $match|grep -v grep|awk '{print $1}'", $output, $ret);
if($ret) return 'you need ps, grep, and awk installed for this to work';
while(list(,$t) = each($output)) {
if(preg_match('/^([0-9]+)/', $t, $r)) {
system('kill '. $r[1], $k);
if(!$k) $killed = 1;
}
}
if($killed) {
return '';
} else {
return "$match: no process killed";
}
}
