How can a beginner troubleshoot and resolve a "Headers and client library minor version mismatch" error in PHP?

To resolve a "Headers and client library minor version mismatch" error in PHP, you need to ensure that the PHP version you are using matches the version of the MySQL client library. This error typically occurs when there is a mismatch between the versions of PHP and the MySQL client library being used. To fix this issue, you can either update the PHP version to match the MySQL client library version or update the MySQL client library to match the PHP version.

// Example code snippet to specify the MySQL client library version in PHP
mysqli_report(MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "username", "password", "database", null, "/path/to/mysql.sock");
