|
|
*
|
|
* Add 3rd (empty) argument in apply_filters() to prevent PHP from throwing an error:
|
|
* “Fatal error: Uncaught ArgumentCountError: Too few arguments to function apply_filters()”
|
|
*
|
|
* Yet get_locale() is defined w/o parameters in wp-includes/l10n.php:30, and
|
|
* apply_filters() is defined as apply_filters( $tag, $value ) in wp-includes/plugin.php:181.
|
|
* @link https://developer.wordpress.org/reference/functions/apply_filters/
|
|
*
|
|
* But apply_filters() is defined with a 3rd parameter (and w/o the first one) in
|
|
* wp-includes/class-wp-hook.php:264, as public function apply_filters( $value, $args ).
|
|
*
|
|
* Taking it all together, probably the full function definition would be:
|
|
* public function apply_filters( $tag, $value, $args ).
|
|
* In the case of get_locale(), $args is empty.
|
|
*
|
|
* The bug was lurking in WP. PHP 7.1 promoted the warning to an error.
