MySQLi database layer


MySQL_* functions is deprecated and this plugin creates a layer to use MySQLi instead. So you don’t get notices when using PHP 5.5

Be sure to read the installation instructions, as this is not a traditional plugin, and on activation you do need to install our database driver by using the settings screen or move manually db.php into your content directory.


  1. Verify that you have MySQLi
  2. Go to the settings page of this plugin and install our driver or just copy db.php to your WordPress content directory (wp-content/ by default)
  3. Done!

It saved my day, I was having a hard time running locally an obsolete website with PHP56 and WordPress 3.5.1… placing db.php from this plugin in my wp-content folder worked! Now I don’t get anymore the error “Your PHP installation appears to be missing…”. Thanks!

I was restoring an old WordPress site (v3.7.1) that I haven’t touched in over 3 years that on my WAMP server. Even though this plugin hasn’t been updated for just as long, it was helpful in fixing the depreciation notices that I was getting for mysqli, thank you.
