Upgrading Your Version of PHP for Fun and Profit

By Leave a Comment

  • What does it mean to upgrade your version of PHP? (start using a newer, better version of PHP to run your site)
  • Why should you do it? (your site will load faster and be more secure)
  • How often should you? (check the releases, but generally…maybe twice a year)
  • Will it hurt? (not if you are doing other stuff right – keeping your themes, plugins and version of WordPress up to date)

Here is what the WordPress community has to say about upgrading your version of php (hint: they’re all for it).  Basically, PHP (which stands for Php Hypertext Preprocessor – pretty cute, that) is the language that runs a WordPress site.  Periodically a new version is developed and released, usually running things faster, better while using fewer resources.  Doing more with less.  The big change was the release of PHP 7.0 in 2015, but as of Nov 2018 we are already up to 7.3

WPEngine has a helpful post about it as well, talking about what PHP is and why you need to keep current.

Overall, PHP 7 is faster, more secure, and significantly more resource efficient than older versions. To give you an example, a site running PHP 7 can handle twice as many visitors as PHP 5 can, using the same amount of memory.

It’s generally agreed that you should aim to be on the latest secure release, not the most recent bleeding edge one.  (though most people are lagging behind updating PHP 7.0 – only less than 1 in 5 sites as of 2018)  And it’s further agreed that you should probably not experience any problems from upgrading to a higher version of PHP.

Probably.

WPMUDEV explains it well:

If you use plugins, themes or scripts on your site that rely on outdated PHP code and you upgrade to a newer version of PHP, the changes from the upgrade would cause old code on your site to be incompatible and break.

It’s not a bad idea to check if your site will be okay with a newer version of PHP by using a plugin like Compatibility Checker.  If you’re always updating WordPress and using reputable, premium, well-supported plugins and themes, you should be all ready to move forward.  However, if your plugin or theme is not being updated frequently, it may not play nicely with a newer version of PHP.  To be honest, you may already be aware of which theme or plugin might cause a problem if something crashed your site after a WordPress version update.  (Remember, if you can’t access the dashboard, you can sftp in or use the cpanel to easily rename and disable your plugins and themes one by one till your site comes back up and you identify the culprit).

A reputable webhost will have the latest couple of versions of PHP available to you to select from via the cpanel.  Remember, you may not be able to upgrade if you’re on a managed WordPress plan (at least from GoDaddy).  And you should always have a backup of your site (files and database) in case things go sideways and you need to restore.

 

 

 

 

Good Habit – Keep Your Hosting and Domain and Backups Separate

By Leave a Comment

You know how the royal family has to travel separately, in order to mitigate risk to the line of succession?  Of course you do, it was the entire plot of King Ralph.  Keeping your domain and hosting separate helps to manage the risk that your site can be hacked.

Think about it – if someone hacks your site, at least they can’t take your domain as well (this is assuming they figured out the account user name and password with the host/registrar).  If they get your domain, that’s a little trickier, but at least your still have your site on the host.  And if your host’s backup of your files fails, at least you have a copy of your site in your DropBox, your Google Drive (and for the extra paranoid, a hard copy of your site on a usb stick, which was a brilliant idea I got from an InMotion support dude.  Not all heroes wear capes, guys)

You’ll also tend to feel kind of stuck if you want to transfer away from that host – and a lot of times those sweet first year hosting plans get pretty pricey the second year.  It doesn’t cost any more to register somewhere other than your web host, and you can just pick one domain registrar and then shop around for a plan to host your sites.  It’s a good habit to spread the risk around and make things harder for hackers.

Also consider two factor authentication and installing wordpress in a subdirectory.  These are simple steps but hackers go for low hanging fruit, so harden up your site, yo.
