PHP: replace all occurrences of “[CODE]…[/CODE]” in a string

Question

I've got a string like this:

Here is my code sample, its not too great:

[CODE]
<?php
    echo "Some testing...";
?>
[/CODE]

I hope you enjoy.

Now I want to replace ALL occurrences of [CODE] ... [/CODE] with the return value of highlight_string($content_of_CODE) . The [CODE]..[/CODE]-pair may appear multiple times in the string.

How can I solve this without using eval?

Thank you for your help!

Answer 1

假设[CODE]块没有嵌套， preg_replace_callback()是一个完美的候选者。

preg_replace_callback('/\[CODE\](.*?)\[/CODE\]/', 'highlight_string');

Answer 2

使用这个正则表达式：

(?s)\[CODE\].*?\[/CODE\]

Answer 3

content_of_CODE = reg_replace（'/ [！\\ s +！] | [\\ s * / * CODE] /'，''，$ content_of_CODE）;
