To unleash the full potential of your WordPress site, it’s often necessary to increase WordPress PHP values. This article will examine the complex aspects of optimizing PHP settings on Ubuntu to make sure that your WordPress website functions quickly and effectively. As a flexible and user-friendly platform, WordPress is unrivaled in the dynamic world of website development. However, as your website grows, you may encounter limitations imposed by default PHP settings.

Requirements for Increasing WordPress PHP Values

Let’s make sure you have everything you need for this journey before exploring the world of PHP optimization. To successfully increase PHP values in WordPress on Ubuntu, you will need:

  1. Ubuntu Server: Ensure you have a server running Ubuntu. This guide is specifically tailored for Ubuntu users, so having the right environment is crucial.
  2. Access to Your Server: Whether you’re using a local server or a remote one, make sure you have the necessary access privileges to modify PHP settings.
  3. WordPress Installed: Your WordPress website should already be up and running on your Ubuntu server. If not, follow our official WordPress installation guide.
  4. SSH Access: Familiarize yourself with Secure Shell (SSH) access to your server. SSH allows you to connect to your server securely and execute commands remotely.
  5. Text Editor: You’ll need a text editor like Nano or Vim to make changes to configuration files.

Before making any changes, it’s important to create a backup of your most recent WordPress installation. To do this, use the UpdraftPlus plugin and follow our instructions on how to successfully create a backup.

Now that you’ve taken care of the necessary steps, let’s get started on increasing the PHP values on your WordPress site.

Understanding WordPress PHP Values and Why They Matter

PHP is the scripting language that powers WordPress. PHP values determine how PHP behaves on your server. Some values control script execution times, memory allocation, and file upload sizes. By increasing these numbers, you can support larger files, manage trickier tasks, and improve the performance of your WordPress website.

Step 1: Locate Your PHP Configuration File

The first step is to locate your PHP configuration file. In Ubuntu, PHP uses separate configuration files for the web server (Apache or Nginx) and the command-line interface (CLI). We’ll focus on the web server configuration.

The most common PHP configuration file for Apache is located at:


For Nginx, it would be:


Replace {PHP_VERSION} with the version of PHP you’re using. You can check your PHP version using the php -v command.

Step 2: Backup Your PHP Configuration File

It’s important to make a backup of your PHP configuration file before making any changes. This makes sure that if something goes wrong, you can go back to the previous settings. The cp command can be used to make a backup:

sudo cp /etc/php/{PHP_VERSION}/apache2/php.ini /etc/php/{PHP_VERSION}/apache2/php.ini.bak

Step 3: Edit PHP Configuration File

Now, open the PHP configuration file using your preferred text editor. For example, to open it with Nano, use:

sudo nano /etc/php/{PHP_VERSION}/apache2/php.ini

Inside the configuration file, you’ll find various PHP directives. We’ll focus on the following commonly adjusted values:

Memory Limit

The memory that PHP can use is managed by this directive. For managing complicated WordPress themes and plugins, increasing WordPress PHP values it is frequently necessary.

Search for memory_limit and adjust it to your desired value. For example:

Upload Max Filesize

This option establishes the largest file size that can be uploaded to your WordPress website. Consider increasing the WordPress PHP values limit if you frequently upload large media files.

Search for upload_max_filesize and set it accordingly:

Post Max Size

This value should be greater than or equal to upload_max_filesize. It controls the maximum size of data that can be POSTed to your WordPress site. Adjust this WordPress PHP values like this:

Max Execution Time

This option manages the maximum runtime for a PHP script. Consider increasing this WordPress PHP values if you have resource-intensive tasks, like importing sizable databases:

Max Input Time

Similar to max_execution_time, max_input_time controls the maximum time PHP waits for input data. Increase it if necessary:

Step 4: Save and Restart Your Web Server

Once you’ve made your desired changes for the WordPress PHP values, save the PHP configuration file and exit the text editor(CTRL+X+Y).

For Apache, restart the web server to apply the new PHP settings:

sudo systemctl restart apache2

For Nginx with PHP-FPM, restart both Nginx and PHP-FPM:

sudo systemctl restart nginx
sudo systemctl restart php{PHP_VERSION}-fpm

Step 5: Verify the Changes

To ensure your WordPress PHP values have taken effect, you can create a PHP info file and access it through your web browser. Here’s how:

Create a file named phpinfo.php in your web server’s document root (typically /var/www/html/):

sudo nano /var/www/html/phpinfo.php

Add the following content:


Save the file and access it in your browser using your server’s IP address or domain followed by /phpinfo.php (e.g., http://your_domain_or_IP/phpinfo.php). You should see a page displaying your PHP configuration settings. Verify that the changes you made are reflected there.


You’ve successfully optimized PHP values for your WordPress website on Ubuntu. Understanding and modifying these WordPress PHP values will help you make sure that your website is capable of handling more demanding operations and resource management. Remember that while increasing PHP values can improve your site’s performance, it should be done judiciously, considering your server’s available resources. Frequent monitoring and occasional adjustments will help you maintain an optimal WordPress experience.

Your WordPress website is now prepared to handle the demands of an expanding online presence thanks to these PHP optimizations.
