php中的proc_open+fwrite应用问题
我想在php用proc_open调用一个c++写的exe程序，由于里面有要求输入参数所以我用fwrite写入终端，php代码如下

fwrite($pipes[0], "q");
fclose($pipes[0]);
while (!feof($pipes[1]))
{
$result = fgets($pipes[1], 1024);
echo "r:$result<br>";
}
fclose($pipes[1]);
// It is important that you close any pipes before calling
// proc_close in order to avoid a deadlock
$return_value = proc_close ($process);
echo "command returned $return_value<br>";
}
?>
