从字符串末尾删除< br [英] remove <br>'s from the end of a string

问题描述

正如标题所述，我有一个像这样的字符串:

as the title says i have a string like this:

$string = "Hello World<br>hello world<br><br>";

现在我想摆脱此字符串末尾的<br>，因此它看起来像这样:

now i want to get rid of the <br>s at the end of this string so it looks like this:

$string = "Hello World<br>hello world";

我尝试过:

preg_replace('/^(<br>)*/', "", $string);

但是这没有用. 也许有人知道正确的正则表达式.

but this did not work. maybe someone knows the right regex.

推荐答案

您很接近，您在正则表达式的开头使用了^，表示匹配字符串的开头".您需要在结尾加上$，表示匹配字符串的结尾".

You're close, you used ^ at the start of the regexp, which means "match the start of the string." You want $ at the end, which means, "Match the end of the string."

preg_replace('/(<br>)+$/', '', $string);
