Understanding PHP & Its Importance For WordPress

In a nutshell, PHP is the heart of your WordPress site. So, keeping it updated is crucial for your site’s health, security, and overall performance.

PHP, or Hypertext Preprocessor, is the soulful script that brings your WordPress site to life.

It translates all the complex code into the beautiful web pages your visitors interact with.

What Is PHP & Its Role In WordPress?

Imagine you’re at a restaurant.

You order your meal (that’s you interacting with a WordPress site), the chef (PHP) whips up your dish behind the scenes, and voila, your meal is served (the final web page).

In WordPress, PHP is that chef, tirelessly working to ensure every click leads to the right outcome, every post is displayed correctly, and your entire site functions just as you intended.

The Impact Of PHP Version On WP Functionality, Security, & Compatibility

Each new PHP version brings improvements to your WordPress site.

These make it faster, more secure against cyber threats, and more compatible with the latest plugins and themes.

It’s like getting a free upgrade to first class, ensuring your site flies high without any turbulence.

Why Update PHP For WordPress Sites?

Keeping PHP updated is akin to regular health check-ups.

Just as you’d want to ensure everything functions optimally for your well-being, your WordPress site needs that same care and attention.

Updating PHP ensures your site is at its best, offering visitors a seamless experience while keeping those pesky cyber threats at bay.

Plus, it ensures your site remains compatible with the latest and greatest WordPress bells and whistles.

This allows you to utilize all the innovative features that come your way.

  • Log in to your hosting account.
  • Find the “PHP Version” or “PHP Configuration” section: Depending on your hosting provider, this could be in different locations. Common spots are under “Software,” “Advanced,” “Pages,”, or directly on the main page.
  • Look for the current PHP version displayed. (This is also usually where you can change the version if you want to upgrade or downgrade.)

Method 3: Creating A PHP Info File

Feeling a bit more adventurous?

Let’s create a magical scroll, or a PHP info file in tech terms.

  • Open a text editor (Notepad or Sublime Text works great) and paste the following magical incantation: ““.
  • Save this file as “phpinfo.php”: Be sure to name it exactly like this, as it’s the key to unlocking the information.
  • Upload this file to your website using an FTP client or the file manager in your hosting control panel. Place it in the root directory, where your WordPress files live.
  • Open a browser and go to “”: Replace “” with your actual domain, and behold, the scroll unfolds, revealing your PHP version among other treasures.

Pro tip: Don’t forget to delete the file afterward to keep your site safe from prying eyes!

Method 4: Via FTP and WP-Config File

For those who enjoy a bit of coding adventure, this method involves delving into the heart of WordPress via FTP.

  • Connect to your site using an FTP client. (You can use Filezilla for this.)
  • Navigate to the “wp-config.php” file: This is the main scroll of your WordPress site.
  • Edit the file and add the following line: “echo ‘Current PHP version: ‘ . phpversion();” at the top, right after “<?php”.
  • Save the file and visit your WordPress admin area: The PHP version is displayed at the bottom, like a secret message only for you.

Pro tip: Skip this method if you’re a beginner and unfamiliar with coding and updating files. (Or at least keep a backup of the wp-config.php file, just in case.)

What To Do If Your PHP Version Is Outdated

3. Post-Upgrade Checks: Ensure Site Functionality & Performance

After the upgrade, it’s essential to ensure your website runs smoothly:

  • Check for intruders: Review your site to ensure all pages load correctly and no features have walked the plank.
  • Monitor the ship’s speed: Use tools (such as Pingdom Tools) to check your site’s performance and speed. Upgrading PHP should make your site faster.
