How can PHP errors in WordPress themes be effectively debugged and resolved?

To effectively debug and resolve PHP errors in WordPress themes, you can enable debugging in WordPress by adding the following code to your wp-config.php file: define( 'WP_DEBUG', true ); define( 'WP_DEBUG_LOG', true ); define( 'WP_DEBUG_DISPLAY', false ); This will log all PHP errors to a debug.log file in the wp-content directory, making it easier to identify and fix any issues in your theme.
