Use a custom-config.php which can be excluded from Git

custom-config.php

<?php

if ( file_exists( dirname( __FILE__ ) . '/custom-config.php' ) ) {
	
	//this handy dandy file can be excluded from your Git or SVN repo!
	//so each developer can use his/her own config :-)
	include( dirname( __FILE__ ) . '/custom-config.php' );
} else {
	
	//production config goes here, example:
	define( 'DB_NAME', 'projectname_prod' );
	define( 'DB_USER', 'projectname_prod_user' );
	define( 'DB_PASSWORD', '12345' );
	define( 'DB_HOST', 'localhost' );
}
