替换两个标签之间的内容

Question

我想使用php替换(和)之间的所有内容。

我的字符串：

$string = "This is a (string)";

所需的输出是：

$string = "This is a";

我的代码不起作用：

$string = "This is a (string)";
$search = "/[^(](.*)[^)]/";
$string = preg_replace($search, "", $string);
echo $string;  // output is ")"

Answer 1

$result = preg_replace('/\(.+?\)/sm', 'Put your text here', $string);

试试此代码

或者将save（）添加到替换

$page = preg_replace('/\(.+?\)/sm', '(Put your text here)', $page);

Answer 2

这应该适合你：

<?php

    $string = "This is a (string)";
    echo preg_replace("/\([^)]+\)/","",$string);

?>

输出：

This is a

Answer 3

改变一下：

$search = "/ *\(.*?\)/";
