  • [RESOLVED] Your PHP installation appears to be missing the MySQL which is required for WordPress

Hi There-

I have PHP 5.1.6 and MySQL 4.1 on IIS6 (Windows 2003). Yesterday we had a drive crash, so I'm working to reinstall all our apps.

Our entire Website runs in PHP, and it's working fine. I've recovered our database files and can access the data via command line on the server. So far, so good.

The issue, though, is that when I try to access my blog:

http://www.articulate.com/blog/

...I get this error:

Your PHP installation appears to be missing the MySQL which is required for WordPress

I've searched far and wide and have tried everything I can find:

  • extension=php_mysql.dll is uncommented and does exist in my C:\Windows\php.ini file

When I check my phpinfo() file, however, I see no references to MySQL, so I'm guessing that's the core of the issue here.

Any suggestions?

Thanks in advance!

    Resolved this!

    I copied libmySQL.dll from C:\Program Files\MySQL\MySQL Server 4.1\bin to C:\PHP and overwrote the version there.

      I got the same problem but it might be different now because it is now 2019 but maybe the solution I presented below might help in case you encounter the same issue. PHP version 5.6 and below is no longer supported in PHP community so it was advised to upgrade to version 7.2 and up. In case of wordpress, old version are using mysql extension but PHP 7.2 version are no longer supported it, mysqli extention was now been used by PHP version 7.2. So older version of wordpress will encounter this problem if PHP versio is upgraded to 7.2.

      So this is what happened. When I upgraded my website from PHP version 5.6 to 7.2, I encountered this problem “Your PHP installation appears to be missing the MySQL extension which is required by WordPress”. It turns out that mysql extension is no longer supported in php version 7.2. It is now using mysqli extention. I am using old version of wordpress which still using mysql extension that is why the problem existed. So what I did is upgraded the wordpress to the core. This solve the problem.

      Here's the steps I followed when upgrading wordpress manually.
      1. First I created a full backup of my website. This is very important in case of mistake.
      2. I download the newest WordPress ZIP file from wordpress.org.
      3. I unzipped the file into a local directory of my computer.
      4. I went to my website root directory and deleted your ‘wp-includes’ and ‘wp-admin’ directories. I used sFTP connection using Filezilla software.
      5. I uploaded the new wp-includes and wp-admin directories from the new version of WordPress I unzipped to my website root directory and replaced the directories I just deleted.
      6. I did not delete the wp-content directory or any of the files in that directory. I just copied over the files from the wp-content directory in the new version of WordPress to my existing wp-content directory. All existing files with the same name have been overwritten.
      7. I copied all files from the root (‘/’) directory of the new version of WordPress that I unzipped into my website root directory (or the root directory of your WordPress installation). Existing files has been overwritten and new files has been copied across. wp-config.php file was not be affected because WordPress has never distributed with a wp-config.php file.
      8. I compare wp-config-sample.php which was\s distributed with WordPress but did not find anything to change so I just used the old one.
      9. I cleared my browser cache to ensure I can see all changes.
      10. I checked the site and there is no error now. Thanks God the upgrade was completed.

      Yes, that extension was removed in version 7.0.0 after being deprecated in 5.5.0. That was in 2015, so isn't the same problem as the one from 2007 that you replied to.

      All in all, it's another good reason to keep your systems up to date (it's not just for security purposes) — the more rarely you update, the more painful it is when you do get around to doing it.
