php 如何利用管道（pipe）与shell互交

如在linux里删除文件file，执行命令
rm file
后就会出现一个选项
rm: remove regular file `file'?

这时再输入不同的指令来完成不同的效果。
这种功能怎么用php脚本实现呢？并且我要获取shell返回的选项信息

据说可以用双向管道来做，proc_open但找了半天也没找到一个有用的例子，哪个牛人给我说说啊～～

Answer 1

$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", "./error-output.txt", "a") // stderr is a file to write to
);
$cwd = '/tmp';
$exta = array('bypass_shell' => true);

$process = proc_open("C:\\APMServ\\APMServ5.2.6\\www\\Lk\\lkwizard.exe", $descriptorspec, $pipes, null, null, $exta);
if (is_resource($process))
{
fclose($pipes[0]);
echo stream_get_contents($pipes[1]);
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\n";
}
