Php腳本同步

Question

我需要在後臺啓動一些php腳本（無需等待），然後等到所有進程終止，類似於屏障的東西（如果您熟悉多線程）。

例子：

//...code... 

run_script('myscript1.php');//it's like an exec but doesen't wait for the script to finish 
run_script('myscript2.php');//it's like an exec but doesen't wait for the script to finish 
run_script('myscript3.php');//it's like an exec but doesen't wait for the script to finish 

do_something(); 

wait_until_all_proc_are_finished();//it will wait until all script are executed 
do_something_else(); 
//.... 

我創建了一個腳本，應該做的伎倆;我在控制檯測試它和它的作品不錯，但它doesen't在PHP頁面的工作，我不明白爲什麼！

class TSync{ 
    private $threads=array(); 
    function tcreate($p){ 
      $tname=tempnam(null,'THS_');//create a temp name    

      $p=addslashes($p);//just to be sure 

      $name=addslashes($tname); 

      $ex= 'php -r "$fp=fopen(\''.$name.'\',\'r+\');flock($fp,LOCK_EX);include(\''.$p.'\');fclose($fp);"'; 

      run_on_background($ex);//execute it on background  

      $this->threads[count($this->threads)]=$tname; 

      return count($this->threads)-1;//returns the thread "id" 

    } 
    function twait($id){ 
     $f=$this->threads[$id];//recover the name 
     /***even this doesen't work*** 
     $fp=fopen($f,'r'); 
     flock($fp,LOCK_EX); 
     fclose($fp); 
     */ 
     echo date("H:i:s"),"#Locking on $f<br/>"; 

     $ex= 'php -r "$fp=fopen(\''.$f.'\',\'r\');flock($fp,LOCK_EX);fclose($fp);"'; 

     exec($ex); 
     unlink($f); 

    } 


} 

$t=new TSync();//create the class 

$f=$t->tcreate(dirname(__FILE__).'/testth.php');//this is a test script that waits 10s 
$t->twait($f);//now you should wait the script,commenting this line should result on the script not waiting 

在控制檯上推出有效的代碼示例（在Windows上進行測試）

start /b php.exe -r "$fp=fopen('C:\\Windows\\Temp\\THS6D7.tmp','w');flock($fp,LOCK_EX);include('C:/.../testth.php');fclose($fp);" 

如果我的代碼多次推出第二腳本將等待第一所以它應該工作。

您應該能夠通過使用Gearman
