PHP proc_open 不起作用 - 给我“数组中缺少句柄限定符" [英] PHP proc_open won't work - gives me "Missing handle qualifier in array"

问题描述

警告:proc_open():C:\...\updatedots.php 第 102 行的数组中缺少句柄限定符

Warning: proc_open(): Missing handle qualifier in array in C:\...\updatedots.php on line 102

我试图打开记事本，然后在 2 秒后关闭它.这是我的代码:

I'm trying to open notepad the close it after 2 seconds. This is my code:

$descriptorspec = array(
    0 => array("pipe" => "r"),
    1 => array("pipe" => "w"),
    2 => array("file" => "logs/errors.txt")
);

// Create child and start process
$child = array("process" => null, "pipes" => array());
$child["process"] = proc_open("notepad.exe > nul 2>&1", $descriptorspec, $child["pipes"]);

知道这个错误是什么意思以及导致它的原因吗?

Any idea what this error means and what causes it?

推荐答案

It is not 0 =>array("pipe" => "r") 但 0 =>数组(管道"，r") ^^

It is not 0 => array("pipe" => "r") but 0 => array("pipe", "r") ^^

此外，在提供文件名时，您需要指定要使用的模式.这适用于我的机器:

Additionally, when giving a filename you need to specify the mode to use. This works on my machine:

$descriptorspec = array(
    0 => array("pipe", "r"),
    1 => array("pipe", "w"),
    2 => array("file", "logs/errors.txt", "a") ); 
// Create child and start process 
$child = array("process" => null, "pipes" => null); 
$child["process"] = proc_open("notepad.exe > nul 2>&1", $descriptorspec, $child["pipes"]);
