Many website platforms require the backbone development of PHP. Like other forms of programming, this is one of those platforms that is in constant development. As a result, you need to know how to update or otherwise change your version of PHP.
Keeping software up-to-date is just one of many ways to keep your site protected. It also ensures you’re benefiting from the latest technology and practices when developing a website. Which PHP version you use will dictate this level of security as well as compatibility with other online apps.
Using the PHP Version Function
From cPanel, scroll down to the “Software” section and click “Select PHP Version.”
Use the drop down selector to choose which version to use.
Click the “Set as current” button to commit to the change.
You’ll also notice you can enable and disable various aspects of PHP using the check boxes available. However, I suggest keeping these set as default unless you are 100 percent sure you know what you’re doing. Disabling or enabling the wrong function may inadvertently cripple your website.
Why would you use older versions of PHP instead of a new one?
One of the most common issues when switching PHP versions is compatibility. Some platforms require certain aspects of an older PHP version to operate because new changes may not be compatible. This gives developers time to make adjustments before upgrading to a new version of PHP.
The last thing you want is an automatic update to PHP and it stops your website from working correctly.
Should you always keep PHP updated to the newest version?
Most developers probably don’t need to worry about compatibility issues. For example, running a basic blog may not be directly affected by requiring older versions of the software. However, you should take the time and test your site to make sure the newest version won’t break it.
Promoting Safety and Security
Even though old versions of software are often compatible with the functionality of your site, it doesn’t mean it’s a good practice to keep the obsolete version running. In fact, old stable versions of software can have exploits you don’t know about. Eventually, old versions are no longer supported by fixes and upgrades. From PHP to new versions of WordPress, it’s safer to keep everything as current as possible.
