Resolving the Unable to Uninstall PHP 7.3 on CentOS 7 Issue: A Step-by-Step Guide

If you're a server administrator or managing a web server, you may encounter issues with PHP, particularly when trying to uninstall older versions before upgrading. This guide focuses on a common problem: being unable to uninstall PHP 7.3 on CentOS 7, despite trying various command-line approaches.

Understanding the Problem

Many users experience frustration when they try to remove PHP via the command line, yet the removal doesn't seem to take effect. In this particular case, the user wasn't able to uninstall PHP 7.3 from their CentOS 7 web server, even after the yum remove php* command was executed. Here’s a summary of the user's attempts:

Checked installed PHP versions using yum list installed | grep php and confirmed that multiple PHP 7.3 packages were installed.

Tried to remove PHP using yum -y remove php*, which returned messages indicating no packages were marked for removal.

Typical Symptoms:

The installation check shows that PHP 7.3 is still present.

The command executed does not return the expected results.

The Solution

After diagnosing the issue, we can conclude that the asterisk (*) is being interpreted by the shell in a way that prevents the removal of PHP packages. The correct approach is to quote the wildcard in the command to prevent the shell from interpreting it before passing it to yum. Here’s how to effectively solve the problem:

Steps to Uninstall PHP 7.3 on CentOS 7

Open the Terminal: Access the command line on your CentOS 7 server. You usually need root or sudo privileges for package management tasks.

By quoting it, you ensure that the command passes the wildcard directly to yum, allowing it to interpret it correctly and remove matching packages.

Verify Removal:
After running the removal command, check again to ensure that PHP has been successfully uninstalled by running:

You should see a message indicating that PHP is not installed.

Reinstall or Upgrade PHP (if needed):

Conclusion

Uninstalling PHP from a CentOS 7 server may seem daunting, especially when the standard commands don't yield expected results.

By following the steps outlined above, you can effectively manage your PHP installations and tackle similar issues confidently in the future.
