命令行模式下,根据传参,调用不同控制器。控制器中根据配置定时执行指定方法
Application.php
<?phpclass Application{public static function main(){header("content-type:text/html;charset=utf-8");self::register();self::commandLine();self::pathInfo();}//自动加载public static function loadClass($class){$class=str_replace("\", "/", $class);$dir=str_replace("\", "/", __DIR__);$class=$dir."/".$class.".php";require_once $class;}//命令行下public static function commandLine(){if(php_sapi_name()=="cli"){$_SERVER["PATH_INFO"]="";foreach ($_SERVER["argv"] as $k=>$v) {if($k==0) continue;$_SERVER["PATH_INFO"].="/".$v;}}}//pathinfo处理public static function pathInfo(){if(isset($_SERVER["PATH_INFO"])){$pathinfo=array_filter(explode("/", $_SERVER["PATH_INFO"]));for($i=1;$i<=count($pathinfo);$i++){$key=isset($pathinfo[$i]) ? $pathinfo[$i] : "";$value=isset($pathinfo[$i+1]) ? $pathinfo[$i+1] :"";switch ($i) {case 1:$_GET["m"]=ucfirst($key);break;case 2:$_GET["c"]=ucfirst($key);break;case 3:$_GET["a"]=$key;break;default:if($i>3){if($i%2==0){$_GET[$key]=$value;}}break;}}}$_GET["m"]=!empty($_GET["m"]) ? ucfirst($_GET["m"]) : "Index";$_GET["c"]=!empty($_GET["c"]) ? ucfirst($_GET["c"]) : "Index";$_GET["a"]=!empty($_GET["a"]) ? $_GET["a"] : "index";$class="\Controller\{$_GET["m"]}\{$_GET["c"]}";$controller=new $class;$controller->$_GET["a"]();}//致命错误回调public static function shutdownCallback(){$e=error_get_last();if(!$e) return;self::errorHandler($e["type"],"<font color="red">Fatal Error</font> ".$e["message"],$e["file"],$e["line"]);}//错误处理protected static function myErrorHandler($errno,$errstr,$errfile,$errline){list($micseconds,$seconds)=explode(" ",microtime());$micseconds=round($micseconds*1000);$micseconds=strlen($micseconds)==1 ? "0".$micseconds : $micseconds;if(php_sapi_name()=="cli"){$break="
";}else{$break="<br/>";}$mes="[".date("Y-m-d H:i:s",$seconds).":{$micseconds}] ".$errfile." ".$errline." line ".$errstr.$break;echo $mes;}//注册public static function register(){error_reporting(0);set_error_handler(function($errno,$errstr,$errfile,$errline){self::myErrorHandler($errno,$errstr,$errfile,$errline);});register_shutdown_function(function(){self::shutdownCallback();});spl_autoload_register("self::loadClass");}}Application::main();
ControllerClientCron.php
<?phpnamespace ControllerClient;class Cron{private $second=0;private $tasks=array(array("duration"=>5,"method"=>"doSomething"),array("duration"=>2,"method"=>"doSomething2"),);public function index(){while (true) {sleep(1);$this->second++;foreach($this->tasks as $task){if($this->second%$task["duration"]==0){$this->$task["method"]();}}}}public function doSomething(){echo "[".date("Y-m-d H:i:s",time())."] doSomething1 ok!
";}public function doSomething2(){echo "[".date("Y-m-d H:i:s",time())."] doSomething2 ok!
";}}
效果:
方法doSomething每隔2秒执行一次
方法doSomething2每隔5秒执行一次
现在执行其他方法是同步的,可以再优化成开新线程执行这些方法,就不会阻塞主线程的定时了
