我已经谷歌了，我无法得到答案。我讨厌 php，但是 php 的人太忙了，我需要帮助！
I want to call a perl script from an html button. But, I just want it to run in the back ground, I don't need to display anything from it... Would something like this work?
我想从 html 按钮调用 perl 脚本。但是，我只是想让它在后台运行，我不需要从中显示任何内容......这样的东西会起作用吗？
<html>
<body>
<p>
<button onclick=<?php exec('test.pl') ?>Run Perl</button>
</p>
</body>
I would prefer not to use cgi, I want to keep this as simple as possible.
我不想使用 cgi，我想让它尽可能简单。
Thanks

That will not works, you have to create an action for that:
那是行不通的，您必须为此创建一个操作：
<?php
if (isset($_POST['button']))
{
exec('test.pl');
}
?>
<html>
<body>
<form method="post">
<p>
<button name="button">Run Perl</button>
</p>
</form>
</body>

Looks like you are trying to call PHP with a JavaScript action. This will not work. You can try submitting a form and executing the PHP code when the form is submitted, like:
看起来您正在尝试使用 JavaScript 操作调用 PHP。这是行不通的。您可以尝试提交表单并在提交表单时执行 PHP 代码，例如：
<?php if (isset($_POST['button'])) { exec('test.pl'); } ?>
<form action="" method="post">
<button type="submit" name="button">Run Perl</button>
</form>

Addressing the 'run in background' part of this problem, you should be able to put an & at the end to force it to the background.
解决此问题的“后台运行”部分，您应该能够在末尾放置一个 & 以强制其进入后台。
So exec('test.pl &');
所以 exec('test.pl &');
