Moreover, examples of every PHP 7 array function (over 75) are demonstrated. The appendix provides a two-dimensional array case study on the logical design of a checkers game. PHP Arrays answers the following questions: Why do we need arrays? When do we need to use arrays? Are arrays efficient? Can arrays reduce coding time?
