Are there any specific configurations or settings in PHP.ini that need to be adjusted for successful MySQL connections in PHP?

To successfully connect to MySQL in PHP, you may need to adjust the `mysqli.default_host`, `mysqli.default_user`, `mysqli.default_pw`, and `mysqli.default_port` settings in the PHP configuration file (php.ini). These settings specify the default host, user, password, and port for MySQL connections in PHP.

; Set default MySQL host
mysqli.default_host = "localhost"

; Set default MySQL user
mysqli.default_user = "root"

; Set default MySQL password
mysqli.default_pw = "password"

; Set default MySQL port
mysqli.default_port = 3306
