Message:

Code Modernization: Use the null coalescing assignment operator for default value assignments.

Replaces verbose "assign a default only if not already set" patterns with the null coalescing assignment operator (??=):

// Before
$args['title'] = $args['title'] ?? '';

// After
$args['title'] ??= '';

Both forms are functionally identical; ??= is shorter and clearer.

Why this is safe

  • ??= requires PHP 7.4, which is already the minimum.
  • The operator is already used elsewhere in core (e.g. wp-includes/l10n.php, wp-includes/view-config.php), so this only makes existing usage consistent.
  • No behavior change.

Follow-up to r63443, r63501.

Props Soean, mukesh27.
See #65823.
