PHP/REGEX:在括号内获取一个字符串 [英] PHP/REGEX: Get a string within parentheses

问题描述

这是一个非常简单的问题，但是我在任何地方都找不到解决方案.

This is a really simple problem, but I couldn't find a solution anywhere.

我尝试使用preg_match或preg_match_all从括号内获取字符串，但不带括号.

I'm try to use preg_match or preg_match_all to obtain a string from within parentheses, but without the parentheses.

到目前为止，我的表情看起来像这样:

So far, my expression looks like this:

\([A-Za-z0-9 ]+\)

并返回以下结果:

3(空心高光)928-129(<-原始字符串)

3(hollow highlight) 928-129 (<- original string)

(空心突出显示)(<-结果)

(hollow highlight) (<- result)

我想要的是括号内的字符串，但没有括号.看起来像这样:

What i want is the string within parentheses, but without the parentheses. It would look like this:

空心高亮

之后我可能会用str_replace之类的东西来代替括号，但这对我来说似乎不是一个很优雅的解决方案.

I could probably replace the parentheses afterwards with str_replace or something, but that doesn't seem to be a very elegant solution to me.

我必须添加什么，因此结果中不包括括号?

What do I have to add, so the parentheses aren't included in the result?

感谢您的帮助，你们很棒！ :)

Thanks for your help, you guys are great! :)

推荐答案

除了转义的括号外，您还需要添加捕获括号.

You just need to add capturing parenthesis, in addition to your escaped parenthesis.

<?php
    $in = "hello (world), my name (is andrew) and my number is [phone]";
    preg_match_all('/\(([A-Za-z0-9 ]+?)\)/', $in, $out);
    print_r($out[1]);
?>

这将输出:

Array ( [0] => world [1] => is andrew [2] => 845 )
