On November 30, 2017 the PHP development team released the PHP 7.2 version, this release added news features, here some of them:

• New object type: Previously the object statement was used to convert one data type to another one e.g. an array to an sdtClass object and/or vice versa, PHP 7.2 introduces the object data type which can be used to specify the type of parameter and/or for the type of a function return.
• Extension loading by name: Now it is not necessary to specify the file extension (.so for Unix, .dll for Windows) when loading an extension allowing greater portability in the php configuration file (php.ini).
• Abstract method overriding: Now an abstract class that inherits from another abstract class can change/overwrite an abstract method of its parent class.
