OK, a simple one to start this thing off. If you’re writing PHP and you need to debug something and print some output to your error logs, here’s a nice custom debugging function that’s easier than the default error_log function. Certainly makes my life a lot easier.

if(!function_exists('_error_log')){
  function _error_log( $stuff ) {
    if( WP_DEBUG === true ){
      if( is_array( $stuff ) || is_object( $stuff ) ){
        error_log( print_r( $stuff, true ) );
      } else {
        error_log( $stuff );
      }
    }
  }
}

Oh, and don’t forget to add the following to your wp-config.php file to turn on debugging, and remember to make sure your server has write access to wp-content/debug.log.

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
@ini_set('display_errors',0);
