Signal library

Signal library allows to define handlers and call methods activated by system signals.

Example


use Apolinux\Signal;

require_once __DIR__ .'/../vendor/autoload.php' ;

// define custom signal by default
Signal::setHandler(SIGUSR1,function($signal){
  Signal::$last_signal=$signal ;
  Signal::setExitStatus('OK');
});

posix_kill(posix_getpid(), SIGUSR1);

$status = Signal::getExitStatus();

// must show "OK" as status
echo "signal exit status: $status".PHP_EOL ;
