mysqli.default_port

INI

MySQLi: mysqli.default_port — Default port number for mysqli_connect(). If unset, mysqli_connect() will use the $MYSQL_TCP_PORT or the mysql-tcp entry in /etc/services or the compile-time value defined MYSQL_PORT (in that order). Win32 will only look at MYSQL_PORT.

Default value 3306
Development value 3306
Production value 3306

Modifiability: INI_ALL - The mysqli.default_port INI directive can be configured anywhere, including php.ini files, ini_set calls, Apache .htaccess files, per-directory .ini files, etc.
