使用方式

composer require mrtwenty/timer

<?phprequire__DIR__ .'/vendor/autoload.php';usetimer\Daemon;$timer = Daemon::runAll();//测试执行 timer类functionmicrotime_float(){list($usec,$sec) =explode("",microtime());returnbcadd($usec,$sec,3);}$timer->add(0.5,function () {if (Daemon::getOS() ===OS_TYPE_WIN) {echomicrotime_float() ."\n";    }else {file_put_contents("/tmp/test.txt",microtime_float() ."\n",FILE_APPEND);    }});$timer->add(1,function () {if (Daemon::getOS() ===OS_TYPE_WIN) {echomicrotime_float() ."once\n";    }else {file_put_contents("/tmp/test.txt",microtime_float() ."once\n",FILE_APPEND);    }},false);$timer->loop();
