WordPress Developer Hint

With WordPress 3.0 debugging will be easier, whereas one constants gets eliminated and an already existing constant will do their work.

For developers the following 3 constants are important and should exist in every wp-config.php of a development system. Please use it with precaution on a live system!

Add define('WP_DEBUG', true); to wp-config.php to enable
the reporting of notices during development.

Add define('WP_DEBUG_DISPLAY', false); to wp-config.php to
disable the display of errors.

Add define('WP_DEBUG_LOG', true); to wp-config.php to log
eerrors to debug.log in the wp-content directory.
Sets PHP error handling and handles WordPress debug mode.

Recommendation for wp-config.php

/** Debugging WP */
define('WP_DEBUG', true); //enable the reporting of notices during development - E_ALL
define('WP_DEBUG_DISPLAY', true); //use the globally configured setting for display_errors and not force errors to be displayed
define('WP_DEBUG_LOG', true); //error logging to wp-content/debug.log
define('SCRIPT_DEBUG', true); //loads the development (non-minified) versions of all scripts and CSS and disables compression and concatenation,
//define('E_DEPRECATED', true); //E_ALL & ~E_DEPRECATED & ~E_STRICT

A small syntax with huge impact. I recommend this to everyone who is developing with WordPress, especially with Xdebug a fantastic help.
