Arrays: PHP 7 Beginners Guide: Single, Multi-dimentional, Associative, and Object Arrays

by Steve Prettyman

Many programmers have a difficult time understanding arrays. PHP 7 Beginners Guide is a first of its kind book which provides an in-depth look at arrays. After a quick overview of the basic PHP 7, each chapter is devoted to a concentration on single, multi-dimensional, associative, and object arrays. In addition, 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.

•Why do we need arrays? When do we need to use arrays?
•Are arrays efficient? Can arrays reduce coding time?
•When do you use multi-dimensional and associative arrays?
•What is an Object Array?

In addition to answering these questions, the code examples demonstrate common 'real world' scenarios. These examples

•Retrieval and storage of array data from an html form
•Retrieval and storage of array data from a text file
•Retrieval and storage of array data from a MySQL database

Complete demonstrations of inserting, appending, updating, and deleting array data are provided. Validation methods insure that the data provided by a user is 'good' before the data is entered into an array. PHP 7 try/catch modules are used to capture exceptions and errors that may be caused by invalid data.
