wp-config.php setup for development and production environments.

If you are developing locally with the domain local.testing.dev where ‘local’ would determine the use of the local connections. You can change local to any string that exists in your development environment’s domain name that does not exist in the production environment.

if(strpos($_SERVER['HTTP_HOST'], 'local') === false){
	define('DB_NAME', 'database_name');
	define('DB_USER', 'user_name');
	define('DB_PASSWORD', 'password');
	define('WP_DEBUG', false);
	
	/** WP Memory Limit */
	define('WP_MEMORY_LIMIT', '1024M');
	
	/** Limit number of post revisions */
	define( 'WP_POST_REVISIONS', 5);

	/** Turn Off PHP Error Reporting */
	error_reporting(0);
	@ini_set(‘display_errors’, 0);
}

if(strpos($_SERVER['HTTP_HOST'], 'local') >= 0){
	define('DB_NAME', 'database_name');
	define('DB_USER', 'user_name');
	define('DB_PASSWORD', 'password');
	define('WP_DEBUG', true);
}
define('FS_METHOD', 'direct'); // For plugin updates etc.

if(strpos($_SERVER['HTTP_HOST'], 'local') === false){

define('DB_NAME', 'database_name');

define('DB_USER', 'user_name');

define('DB_PASSWORD', 'password');

define('WP_DEBUG', false);

/** WP Memory Limit */

define('WP_MEMORY_LIMIT', '1024M');

/** Limit number of post revisions */

define( 'WP_POST_REVISIONS', 5);

/** Turn Off PHP Error Reporting */

error_reporting(0);

@ini_set(‘display_errors’, 0);

}

if(strpos($_SERVER['HTTP_HOST'], 'local') >= 0){

define('DB_NAME', 'database_name');

define('DB_USER', 'user_name');

define('DB_PASSWORD', 'password');

define('WP_DEBUG', true);

}

define('FS_METHOD', 'direct'); // For plugin updates etc.

To use the same config file for different environments I have been using this a lot these days:

if(strpos($_SERVER['HTTP_HOST'], 'local') === false){
	define('DB_NAME', 'database_name');
	define('DB_USER', 'username');
	define('DB_PASSWORD', 'password');
	define('WP_DEBUG', false);
	
	/** WP Memory Limit */
	define('WP_MEMORY_LIMIT', '1024M');
	
	/** Limit number of post revisions */
	define( 'WP_POST_REVISIONS', 5);

	/** Turn Off PHP Error Reporting */
	error_reporting(0);
	@ini_set(‘display_errors’, 0);
}

if(strpos($_SERVER['HTTP_HOST'], 'local') >= 0){
	define('DB_NAME', 'database_name');
	define('DB_USER', 'user_name');
	define('DB_PASSWORD', 'password');
	define('WP_DEBUG', true);
}

if(strpos($_SERVER['HTTP_HOST'], 'local') === false){

define('DB_NAME', 'database_name');

define('DB_USER', 'username');

define('DB_PASSWORD', 'password');

define('WP_DEBUG', false);

/** WP Memory Limit */

define('WP_MEMORY_LIMIT', '1024M');

/** Limit number of post revisions */

define( 'WP_POST_REVISIONS', 5);

/** Turn Off PHP Error Reporting */

error_reporting(0);

@ini_set(‘display_errors’, 0);

}

if(strpos($_SERVER['HTTP_HOST'], 'local') >= 0){

define('DB_NAME', 'database_name');

define('DB_USER', 'user_name');

define('DB_PASSWORD', 'password');

define('WP_DEBUG', true);

}

Putting development connection settings in the ‘local’ and live settings in the not ‘local’.

Debug wp-config.php Settings

Useful debug settings for the wp-config.php file:

define(‘WP_DEBUG’, true); – Turn on warnings and notices.

define(‘WP_DEBUG_LOG’, true); – Log those warnings and notices to wp-content/debug.log

define(‘WP_DEBUG_DISPLAY’, false); – Don’t display them just log them to debug.log. (Publicly accessible if location is not changed)

ini_set( 'log_errors', 1 );
ini_set( 'error_log', WP_CONTENT_DIR . '/debug.log' );

1 2	ini_set( 'log_errors', 1 ); ini_set( 'error_log', WP_CONTENT_DIR . '/debug.log' );

Write to debug.log file.

With define(‘WP_DEBUG_LOG’, true); set in wp-config.php you can write to the debug log from your script with:

write_log( string );

if (!function_exists('write_log')) {
    function write_log ( $log )  {
        if ( true === WP_DEBUG ) {
            if ( is_array( $log ) || is_object( $log ) ) {
                error_log( print_r( $log, true ) );
            } else {
                error_log( $log );
            }
        }
    }
}

if (!function_exists('write_log')) {

function write_log ( $log ) {

if ( true === WP_DEBUG ) {

if ( is_array( $log ) || is_object( $log ) ) {

error_log( print_r( $log, true ) );

} else {

error_log( $log );

}
