Question

I have a spammer that use my PHP e-mail contact form and write this in the mail message:

[url=http://qjtouvifclfk.com/]qjtouvifclfk[/url]
[link=http://gqmrjhtujkoe.com/]gqmrjhtujkoe[/link]
http://tkihpjlwszyw.com/

I want to search for anything that ha [url= and [/url] and [link= and [/link] and http:// and .com in the message and remove it.

Answer 1

preg_replace("/\[url=(.*)\](.*?)\[\/url]\/i", "", $text);
preg_replace("/\[link=(.*)\](.*?)\[\/link]\/i", "", $text);
preg_replace("/http:\/\/\/i", "", $text);
preg_replace("/\.com/i", "", $text); //this is very agresive line!
