PHP Documentation

<?php
/**
	 * Short-circuits deleting metadata of a specific type by meta ID.
	 *
	 * The dynamic portion of the hook name, `$meta_type`, refers to the meta object type
	 * (post, comment, term, user, or any other type with an associated meta table).
	 * Returning a non-null value will effectively short-circuit the function.
	 *
	 * Possible hook names include:
	 *
	 *  - `delete_post_metadata_by_mid`
	 *  - `delete_comment_metadata_by_mid`
	 *  - `delete_term_metadata_by_mid`
	 *  - `delete_user_metadata_by_mid`
	 *
	 * @since 5.0.0
	 *
	 * @param null|bool $delete  Whether to allow metadata deletion of the given type.
	 * @param int       $meta_id Meta ID.
