Why XAMPP Fails to Connect to MySQL
So the Thing is XAMPP is a Local Server Package that bundles Apache MySQL PHP and Perl together. When you load your website WordPress or any PHP Script wp-Config.phpfile attempts to connect to the MySQL database. Otherwise if the database credentials (such as The Database Name Username or Password) do Not match or the MySQL service crashes on port 3306 The connection is Immediately Broken.
Actually Many times some 0ther software or Skype/World Wide Web Service in the background occupies the same port due to which MySQL Does not start.
Main Reasons Behind Localhost Database errors:
Incorrect Database Credentials in Config File: If You wp-config.phphave config.phpwritten the database name username (default root) or password incorrectly in the config file then an error is sure to occur.
Stopped or Crashed MySQL Service: If the MySQL module is not starting in the XAMPP control panel and unexpected shutdown is shown then the connection will not be established.
Corrupted Database Files (InnoDB Corruption): Sometimes due to system crash datathe files in XAMPP folder get corrupted due to which the database cannot be read.
