使用Preg_Replace删除文本

Question

I have some text like the following example:

Some Text Here
[code]Some link[/code]
Text
[code]Link[/code]
Other Text
[code]Another Link[/code]
Other Text1

I want to remove all the text above, under, and between the two code. Here's an example of the output I want:

[code]Some Link[/code]
[code]Link[/code]
[code]Another Link[/code]

I use preg_replace for removing text above the first Code, in this way:

$message = preg_replace('/(.*?)\[code/si','[code',$message, 1);

Can you help me to remove the other text, using preg_replace?

Answer 1

Assuming you can never have [code] abc [code] def [/code] ghi [/code], try this:

do {
    $message = preg_replace("((?:\[code\].*?\[/code\])*).*?(?=\[code\]))is","$1",$message,-1,$c);
} while($c);
