关于xajax的问题

[qqwx_1986]

xajax的注册函数如下

function deal($form,$type)
{
	$objResponse=new xajaxResponse();
	$objResponse->alert( "formData: " . print_r( $form, true ) );
        //其他代码
        return $objResponse;
}

如果我在其他代码出不加入任何代码，很正常，会弹出alert框
但是如果我在其他代码处加上一些特定的代码:

	$proc = new proc_mgr();
	if( !$proc->init() )
	{
		$objResponse->assign( "testdiv", "innerHTML", "init failed!");
		return $objResponse;
	}
	$proc->cmd("start 0");

具体的proc_mgr如下

class proc_mgr
{
	private $process;
	private $descriptorspec;
	private $pipes;
	private $quit;
	private $sp;
	public function __construct()
	{
		$this->sp = CMD_BR;
		$this->quit = CMD_QUIT.CMD_BR;
		$this->descriptorspec = array(
		   0 => array("pipe", "r"),  // stdin is a pipe that the child will read from
		   1 => array("pipe", "w"),  // stdout is a pipe that the child will write to
		   2 => array("file", PCC_DIR."/webpcc-err-log.txt","a") // stderr is a file to write to
		);
		//stream_set_blocking ( $this->descriptorspec, true);
	}
	public function __destruct()
	{	
		release();
	}
	public function init()
	{
		$this->process = proc_open(PCC_EXE, $this->descriptorspec,$this->pipes,PCC_DIR);
		if( !is_resource($this->process) )
		{
			return false;
		}
		return true;
	}
	public function release()
	{
		return proc_close($this->process);;
	}
	public function quitproc()
	{
		fwrite($this->pipes[0], $this->quit);
		fclose($this->pipes[0]);
		while ( !feof($this->pipes[1]) ) 
		{
			$result .= stream_get_contents($this->pipes[1]);
		}
		fclose($this->pipes[1]);
		return $result; 
	}
	public function cmd($strcmd)
	{
		$cmds = $strcmd.$this->sp.$this->quit;
		fwrite($this->pipes[0], $cmds);
		fclose($this->pipes[0]);
		$result = "";
		while ( !feof($this->pipes[1]) ) 
		{	
			//$result = $this->fgets($this->pipes[1], 4096);
			$result .= stream_get_contents($this->pipes[1]);
			//echo $result;
		}
		fclose($this->pipes[1]);
		return $result;
	}
		
	public function cmds($listcmd)
	{
		$count = count($listcmd);
		for( $i=0; $i<$count; ++$i )
		{
			$cmd .= $listcmd[$i];
			$cmd .= $this->sp;
		}
		$cmd .= $this->quit;
		return $this->cmd($cmd);
	}
}

也就是只要加入了proc_mgr相关代码后，xajaxResponse的所有方法（alert assign）都失效了，求高手解答，万分感谢

表示没有用过！

[acabin]

if( !$proc->init() )
这里没通过，就是$proc->init() == false


public function init()
{
$this->process = proc_open(PCC_EXE, $this->descriptorspec,$this->pipes,PCC_DIR);
if( !is_resource($this->process) )
{
return false;
}
return true;
}

检查这里的proc_open是不是有问题

顶一下，有高手给看看么

[xuzuning]

第一段代码中 return $objResponse; 总是被执行的
而第二段代码中 return $objResponse; 被放在条件分支里

现在用 xajax 的不多了，没有环境也说不出什么
