If you want to forcefully use the global PHP.ini settings for cPanel clients, there are a few steps you can follow. First, you'll need to log in to your WHM account as the root user. From there, you can navigate to the "Service Configuration" section and click on "PHP Configuration Editor."
Once you're in the PHP Configuration Editor, you can select the PHP version that you want to modify and click on the "Advanced Mode" button. This will allow you to see a list of PHP settings that can be modified.
Next, you'll need to locate the specific setting that you want to enforce globally. Once you've found it, you can select the "Editor" option to modify its value. In the editor window, you can set the value of the setting to the desired value and click on the "Save" button to save your changes.
After you've saved your changes, you'll need to navigate back to the "Basic Mode" and click on the "Apply" button to apply the changes to all cPanel accounts. It's important to note that some cPanel users may have already modified their PHP settings, which can override the global settings that you've just enforced.
Enforcing global PHP.ini settings for cPanel clients requires a few steps, but it can be done relatively easily through the PHP Configuration Editor in WHM. By following these steps, you can ensure that all cPanel accounts on your server are using the same PHP settings, which can help to avoid potential conflicts or issues.
