wpdb::__set() WordPress Method

The wpdb::__set() method sets a property of the wpdb class and returns the old value. This is useful for setting a property to a new value and then doing something with the old value, such as setting it back to the original value after doing something else.

wpdb::__set( string $name, mixed $value ) #

	public function __set( $name, $value ) {
		$protected_members = array(
			'col_meta',
			'table_charset',
			'check_current_query',
		);
		if ( in_array( $name, $protected_members, true ) ) {
			return;
		}
		$this->$name = $value;
	}
