ereg_replace to preg_replace

Hi there, I have a very old TL installation 2.6.7 which has in controller.php

Code:

---

$strGdVersion = ereg_replace('[[:alpha:][:space:]()]+', '', $arrGdinfo['GD Version']);

---

Just a few days back my Hoster has upgraded PHP version to 5.3, and this causes a problem resulting in black jpg/jpeg pictures.

Without thinking much I've changed the above from a newer contao to (As i knew ereg function is depricated in php 5.3)

Code:

---

$strGdVersion = preg_replace('/[^0-9\.]+/', '', $arrGdinfo['GD Version']);

---

and it works. But I am not sure if this might lead to other problems. Is it ok with what I have done? Thanks

Hi,

Contao uses preg_replace() from 2.9.5 at least.
