This example shows how to pass along CTRL+BREAK
events to a child
process. In this case the child process echoes I'm still alive
every second, until the user presses CTRL+BREAK
, what causes
only the child process to be terminated.
<?php
// forward CTRL+BREAK events to the child process
sapi_windows_set_ctrl_handler('sapi_windows_generate_ctrl_event');
// create a child process which echoes every second
$cmd = ['php', '-r', 'while (true) { echo "I\'m still alive\n"; sleep(1); }'];
$descspec = array(['pipe', 'r'], ['pipe', 'w'], ['pipe', 'w']);
$options = ['create_process_group' => true];
$proc = proc_open($cmd, $descspec, $pipes, null, null, $options);
while (true) {
echo fgets($pipes[1]);
}
?>
