If I have this on my webpage :
$f = popen("/home/username/bin/something --json arg1 arg2", "rb");
while (($line = fgets($f)) !== false) {
$event = json_decode($line);
// do something
}
fclose($f);
If the the browser closes unexpectedly, will the execution of /home/username/bin/something
stop ? I need it to be finished even if the browser tab closes.
