/**
* Sets PHP error handling.
* Sets PHP error handling and handles WordPress debug mode.
*
* Add <code>define('WP_DEBUG', true);</code> to wp-config.php to enable
* the reporting of notices during development.
* Uses three constants: WP_DEBUG, WP_DEBUG_DISPLAY, and WP_DEBUG_LOG. All three can be
* defined in wp-config.php. Example: <code> define( 'WP_DEBUG', true ); </code>
*
* Add <code>define('WP_DEBUG_DISPLAY', false);</code> to wp-config.php to
* disable the display of errors.
* WP_DEBUG_DISPLAY and WP_DEBUG_LOG perform no function unless WP_DEBUG is true.
* WP_DEBUG defaults defaults to false.
*
* Add <code>define('WP_DEBUG_LOG', true);</code> to wp-config.php to log
* eerrors to debug.log in the wp-content directory.
* When WP_DEBUG is true, all PHP notices are reported. WordPress will also display
* notices, including one 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 authors use WP_DEBUG for their
* development environments.
*
* When WP_DEBUG_DISPLAY is true, WordPress will force errors to be displayed.
* WP_DEBUG_DISPLAY defaults to true. Defining it as false prevents WordPress from
* changing the global configuration setting. (Defining WP_DEBUG_DISPLAY as false
* will never force errors to be hidden.)
*
* When WP_DEBUG_LOG is true, errors will be logged to wp-content/debug.log.
* WP_DEBUG_LOG defaults to false.
