WordPress Debug mode for developing

wp-config.php

<?php
/**
 * For developers: WordPress debugging mode.
 *
 * Change this to true to enable the display of notices during development.
 * It is strongly recommended that plugin and theme developers use WP_DEBUG
 * in their development environments.
 *
 * For information on other constants that can be used for debugging,
 * visit the Codex.
 *
 * @link https://codex.wordpress.org/Debugging_in_WordPress
 */
$debug=true;// Turn on/off Wordpress debugging (and log it in debug.log)
if($debug) {
    // Turn debugging on
    define('WP_DEBUG', true);
    // Tell WordPress to log everything to /wp-content/debug.log
    define('WP_DEBUG_LOG', true);
    // Turn on the display of error messages on your site
    define('WP_DEBUG_DISPLAY', true);
}
else {
    define('WP_DEBUG', false);
    define('WP_DEBUG_LOG', false);
    define('WP_DEBUG_DISPLAY', false);
}

This is the debug settings I use when developing new WordPress sites.
