Regular expression, replace between “<” and “>”, php

Question

I'm very weak in regular expressions.

I simply need to replace < and > (and anything between) with new content.

This is what I have:

$key = preg_replace('/<.*>/', '', $key);

My little string <5> should simply be My little string .
My little string <96> should simply be My little string .

What did I do wrong?

Answer 1

The following works if you supply the string instead of $key :

preg_replace('/<.*>/', '', 'My little string <96>');

What is the value of $key ?

Answer 2

$key必须等于要替换的字符串。正则表达式没有任何问题。
