WordPress PHP Versions: Best PHP for WordPress in 2023

Learn about supported PHP versions.

New versions of PHP are released regularly. In addition to other functional and performance improvements, these updates usually include bug fixes and security improvements. Each version of PHP is usable for three years from the time of release. The support period for each PHP version includes two main support phases:

Two years of active support: Support includes fixing bugs and security issues during this period.
One year of security support: Support only includes fixing critical security issues during this period.

After three years of the support period, the version reaches its end of life (EOL) and is no longer supported. Using an unsupported version of PHP is not recommended at all; it may expose security vulnerabilities and software bugs.
Current WordPress PHP versions

The official PHP website maintains a unique page for checking the status of supported versions. Therefore, the current PHP versions that can be safely used for WordPress are:

When an older PHP programming language is deprecated, it is removed from the list, and a new version with full support is usually added.

PHP requirements in WordPress

WordPress generally has specific server requirements, including PHP requirements, hosting details, and other software dependencies.

Technically, each version of WordPress is compatible with specific versions of PHP. However, although the software may work with older versions of PHP that have reached end-of-life, the platform recommends using only supported versions of PHP.

Note: The compatible PHP version is the version that WordPress needs to work correctly, regardless of whether it is still supported or not.

Here is a list of compatible PHP versions for each WordPress version, keeping in mind that we only consider WP versions that can work with currently supported PHP versions:

Minimum PHP version of WordPress

Each version of WordPress requires a specific minimum version of PHP. However, WordPress recommends using at least a supported version of PHP, regardless of your WordPress installation.

The minimum WordPress PHP version is PHP 8.0.

Minimum WordPress PHP version (unsupported): PHP 5.6.20+ (this version is no longer supported and may expose your site to severe vulnerabilities and bugs)

We advise you not to use it if the minimum PHP version is not supported, even if it is compatible with your website’s version of WordPress.

For this reason, here we also mention the minimum PHP requirements for each WordPress installation version. However, you should know that we only cover WordPress compatible with supported PHP versions.

What is the recommended PHP version for WordPress?

To install and use WordPress, you need specific versions of PHP. The recommended WordPress PHP version depends on the WordPress version you are using. The recommended version for WordPress PHP is the latest supported version compatible with your website’s version of WordPress.

What is the latest version of PHP for WordPress?

PHP is constantly working to update its framework and fix bugs and security issues. WordPress plans to support new PHP versions as they are released. The latest PHP version currently supported by WordPress is PHP 8.2 and is supported by WP 6.1.

However, WordPress compatibility with PHP 8. x is still in beta support. However, most of the WordPress functions will work, but sometimes you may face some minor problems.

Some plugins and skins are not yet compatible with PHP 8. x. Therefore, checking the compatibility of your plugins and skisecs is recommended before updating to new PHP versions.

Here, you will see your website’s PHP version and other server details.

 

What’s the point of keeping your PHP version up to date?

One of the most important things you should do as a site administrator is to keep your PHP version up to date. But why should we do this, and what advantages can this work have?

Maintain and increase security.

The first important reason to update PHP is security. Updating your PHP system will be more secure and protected from hacking attacks and future damage. Versions before PHP 7.4 no longer receive security updates and are, therefore, vulnerable to attacks.

Like other major systems, PHP is constantly being updated and developed, and each new version that is released has a wide range of changes implemented to increase security and solve problems, which is why we recommend always be aware of PHP updates and updating them regularly.

Improving Performance

With the release of new versions of PHP, the performance of this language has improved significantly. PHP is a critical and colossal programming language that should constantly be updated to always take precedence over your other platform optimizations and updates. With PHP 7 installed, your system can execute requests twice as fast per second, almost half as quickly as previous versions. According to benchmark tests, PHP 7.3 runs nearly three times more requests per second than PHP 5.6 and is 9% faster than PHP 7.2 on average. Also, according to the chart provided by Christian Vigh, PHP 5.2 is about 400% slower than PHP 7.

Providing the latest features to developers

Each update brings many changes and provides users with different features. For example, version 7 is very different from previous versions, making programming faster, better,, and safer. Also, extensions and plugins are more compatible with newer versions of PHP and are written to more recent versions of PHP.

Changes that happen in new versions of PHP include:

Support

Here we talk about two types of support for the PHP language. Security support only includes updates that are released to fix reported security issues. But the primary support includes updating the PHP version and adding new features. Each license for the PHP language has a specific duration and can be used as long as the update is active. So if you are using PHP language, try to use a version that receives new updates.

Standardization of plugins

When you change the PHP version of your site, the plugins will be unified and better editable. Also, connecting to newer plugins is easily possible.
Providing the possibility of using new capabilities and features

Changing the PHP version of the site allows you to use better and unique features of this programming language.

increasing speed

Changing the PHP version of the site increases the speed of different platforms. For example, in the Drupal content management system, by changing the site’s PHP version to version 7 or higher, the site’s speed increases by 75%, and this positive effect in the framework also reaches 95% for processing speed in one second.

 

According to the mentioned benefits, changing the PHP version of the site is done for necessary and sufficient reasons. But you should pay attention to the fact that how these changes are made is essential.

How to change the PHP version of the site

Depending on your platforms, there are different ways to update the PHP version. PHP is an open-source language that you can run and use on different systems. Next, we will check how to update PHP on other platforms:

If you don’t know if this feature is active in your direct admin or not, you can find out by running the following code:

/usr/local/DirectAdmin/DirectAdmin config | grep php_version_selector

 

 

If you use this code and find that php_version_selector is disabled, you can use the following code to enable it:

 

/usr/local/DirectAdmin/DirectAdmin set php_version_selector ۱ restart

 

Use a different PHP version for the subdomain.

You can install a specific version of PHP for a subdomain. To do this, there are two methods in front of you: one through the graphic panel and the other through the command line.

To set the PHP version through the DirectAdmin graphical panel, you must apply settings in the DirectAdmin.conf file and have at least two versions of PHP installed on the system. Follow the steps below to do this:

  1. Log in to DirectAdmin.
  2. Select Sub-Domains Setup.
  3. Select Document Root Override.
  4. For each subdomain, select the desired version. To set the PHP version via computer, you can follow these steps: Enter the corresponding directory:
/usr/local/DirectAdmin/data/users/USERNAME/domains/DOMAIN.COM.subdomains.docroot.override

 

In CustomBuild options.conf depending on your settings, use:

php1_select=1-5

 

We give an example for a better explanation; If you change the php1_select setting to 2, the php2_release and php2_mode settings for the corresponding subdomain will be used. In the file below, each subdomain is on a separate line.

domain.com.subdomains.docroot.override

If your subdomain is sub.domain.com, you can do the following:

sub=php1_select=۲

Each different domain path, a different PHP version

This is possible if you want to use different PHP versions for each path and domain. Of course, you should check whether your mod_php has this possibility. For this, you need to enter the custom build.conf file in DirectAdmin and follow the steps below:

mod_php

mod_php settings usually are in default mode. You can use the following two methods to change this section:

Open the htaccess file in the public_html folder and add the commands php_admin_flag / php_admin_value.
Enter the main admin level, open Custom Httpd Config, and add php_admin_flag / php_admin_value commands.

php-fpm

php-fpm allows you to choose multiple php versions for different domains and paths. Using PHP-fpm, users can manually determine the PHP version through their panel. Because php-fpm is located on their independent server.

fastcgi

One of the other methods that can make this feature possible for you is the fastcgi method. To do this, just create an .ini file manually at /usr/local/directadmin/data/users/username/php/domain.com.ini for fastcgi to read.

Using the plugin to manage and update the PHP version in Direct Admin from within the panel

There is a small program for managing and updating the PHP version in DirectAdmin that you can use from within your DirectAdmin.
