Validate constants provided with --extra-php to avoid PHP notices #148
Description
The example on the wp config create command's page has an issue. When I create a config like this:
wp config create --dbname=testing --dbuser=wp --dbpass=securepswd --extra-php <<PHP
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
PHP
It adds the debug true, not seeing that by default debug false is already set. This creates warnings on every consecutive run of wp and also adds these to the log.
When doing wp config set WP_DEBUG true --raw instead, it changes the existing false setting to true, or creates it...
Should we be checking for these constants when adding them with --extra-php?
