pcntl_signal_dispatch — Calls signal handlers for pending signals
The pcntl_signal_dispatch() function calls the signal handlers installed by pcntl_signal() for each pending signal.
Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.
Beispiel #1 pcntl_signal_dispatch() example
<?php
echo "Installing signal handler...\n";
pcntl_signal(SIGHUP, function($signo) {
echo "signal handler called\n";
});
echo "Generating signal SIGHUP to self...\n";
posix_kill(posix_getpid(), SIGHUP);
echo "Dispatching...\n";
pcntl_signal_dispatch();
echo "Done\n";
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
Installing signal handler... Generating signal SIGHUP to self... Dispatching... signal handler called Done
If you are running PHP as CLI and as a "daemon" (i.e. in a loop), this function must be called in each loop to check if new signals are waiting dispatching.
