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

我试图打开记事本并在 2 秒后将其关闭。这是我的代码：

$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"]);

知道这个错误意味着什么以及导致它的原因吗？

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

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"]);

Any idea what this error means and what causes it?

它不是 0 =>; array("pipe" => "r") 但0 => array("pipe", "r") ^^

此外，在给出文件名时，您需要指定要使用的模式。这适用于我的机器：

$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"]);

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

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"]);
