PHP 5 Upgrade

We’re going to be upgrading all the Mr.Host web servers to the newest version of PHP5 (5.2.6) from the current version (4.4.8) we’re running, in the next few weeks.

For those of you using PHP for your web applications, we’ve setup a temporary test URL, running PHP 5.2.6, for all your sites on port 81 (the default web port is 80)- so for example, you can access your site on both:

http://www.mrhost.ca/ (port 80 – PHP4)


http://www.mrhost.ca:81/ (port 81 – PHP5)

Replacing www.mrhost.ca with your website URL.

Most websites should not see any difference between the two versions of PHP, but we are encouraging you to completely test your site under this new test URL; all of the issues related to this upgrade are available here:


For those of you not using PHP on your website, you have absolutely nothing to do for this upgrade.

Not sure if you’re affected? Let us know, and we can figure it out for you.

We’ll be aiming to make the final switch for Nov 9th, barring any major issues.

If you have any questions, please don’t hesitate to e-mail us.
