关于xajax的问题
xajax的注册函数如下

PHP code

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:

PHP code

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

具体的proc_mgr如下

PHP code

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

[解决办法]
表示没有用过！
[解决办法]
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
[解决办法]
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
