More Information More Information

  • This function allows plugin and theme authors to more easily differentiate how they handle specific functionality between production and development sites in a standardized way.
  • When development is returned by wp_get_environment_type(), WP_DEBUG will be set to true if it is not defined in the wp-config.php file of the site.
  • All hosts that support setting up staging environments are requested to set this feature to staging on those staging environments. Similarly, all developers with development environments to set this value to development appropriately.

Example Usage:

switch ( wp_get_environment_type() ) {
    case 'local':
    case 'development':
    case 'staging':
    case 'production':
