| wp_populate_basic_auth_from_authorization_header() X-Ref |
| Populates the Basic Auth server details from the Authorization header. Some servers running in CGI or FastCGI mode don't pass the Authorization header on to WordPress. If it's been rewritten to the `HTTP_AUTHORIZATION` header, fill in the proper $_SERVER variables instead. since: 5.6.0 |
| wp_check_php_mysql_versions() X-Ref |
| Check for the required PHP version, and the MySQL extension or a database drop-in. Dies if requirements are not met. since: 3.0.0 |
| wp_get_environment_type() X-Ref |
| Retrieves the current environment type. The type can be set via the `WP_ENVIRONMENT_TYPE` global system variable, or a constant of the same name. Possible values are 'local', 'development', 'staging', and 'production'. If not set, the type defaults to 'production'. return: string The current environment type. since: 5.5.0 since: 5.5.1 Added the 'local' type. since: 5.5.1 Removed the ability to alter the list of types. |
| wp_favicon_request() X-Ref |
| Don't load all of WordPress when handling a favicon.ico request. Instead, send the headers for a zero-length favicon and bail. since: 3.0.0 |
| wp_maintenance() X-Ref |
| Die with a maintenance message when conditions are met. The default message can be replaced by using a drop-in (maintenance.php in the wp-content directory). since: 3.0.0 |
| wp_is_maintenance_mode() X-Ref |
| Check if maintenance mode is enabled. Checks for a file in the WordPress root directory named ".maintenance". This file will contain the variable $upgrading, set to the time the file was created. If the file was created less than 10 minutes ago, WordPress is in maintenance mode. return: bool True if maintenance mode is enabled, false otherwise. since: 5.5.0 |
| timer_float() X-Ref |
| Get the time elapsed so far during this PHP script. Uses REQUEST_TIME_FLOAT that appeared in PHP 5.4.0. return: float Seconds since the PHP script started. since: 5.8.0 |
| timer_start() X-Ref |
| Start the WordPress micro-timer. return: bool Always returns true. since: 0.71 |
| timer_stop( $display = 0, $precision = 3 ) X-Ref |

Accepts 0|false for return, param: int $precision The number of digits from the right of the decimal to display. return: string The "second.microsecond" finished time calculation. The number is formatted since: 0.71 |
| wp_debug_mode() X-Ref |
| Set PHP error reporting based on WordPress debug settings. Uses three constants: `WP_DEBUG`, `WP_DEBUG_DISPLAY`, and `WP_DEBUG_LOG`. All three can be defined in wp-config.php. By default, `WP_DEBUG` and `WP_DEBUG_LOG` are set to false, and `WP_DEBUG_DISPLAY` is set to true. When `WP_DEBUG` is true, all PHP notices are reported. WordPress will also display internal notices: when a deprecated WordPress function, function argument, or file is used. Deprecated code may be removed from a later version. It is strongly recommended that plugin and theme developers use `WP_DEBUG` in their development environments. `WP_DEBUG_DISPLAY` and `WP_DEBUG_LOG` perform no function unless `WP_DEBUG` is true. When `WP_DEBUG_DISPLAY` is true, WordPress will force errors to be displayed. `WP_DEBUG_DISPLAY` defaults to true. Defining it as null prevents WordPress from changing the global configuration setting. Defining `WP_DEBUG_DISPLAY` as false will force errors to be hidden. When `WP_DEBUG_LOG` is true, errors will be logged to `wp-content/debug.log`. When `WP_DEBUG_LOG` is a valid path, errors will be logged to the specified file. Errors are never displayed for XML-RPC, REST, `ms-files.php`, and Ajax requests. since: 3.0.0 since: 5.1.0 `WP_DEBUG_LOG` can be a file path. |
| wp_set_lang_dir() X-Ref |
| Set the location of the language directory. To set directory manually, define the `WP_LANG_DIR` constant in wp-config.php. If the language directory exists within `WP_CONTENT_DIR`, it is used. Otherwise the language directory is assumed to live in `WPINC`. since: 3.0.0 |

| Load the database class file and instantiate the `$wpdb` global. since: 2.5.0 |
