How can I convert ereg expressions to preg in PHP?

How do i convert this code to php 5.3:

if (eregi("VERIFIED",$this->ipn_response)) { }

---

if (preg_match("/VERIFIED/i",$this->ipn_response)) { }

If you are looking for a fixed text like VERIFIED you shouldn't use regular expressions because they use unnecessary overhead.

if(stripos('VERIFIED', $this->ipn_response) !== false) { }

That should also do the job. Note that stripos() returns the position of the string you are looking for, so it could return zero to indicate a match. It returns boolean false if the string you are looking for is not present.
