These functions allow you to interact with and manipulate
arrays in various ways. Arrays are essential for storing,
managing, and operating on sets of variables.
Simple and multi-dimensional arrays are supported, and may be
either user created or created by another function.
There are specific database handling functions for populating
arrays from database queries, and several functions return arrays.
Please see the Arrays
section of the manual for a detailed explanation of how arrays are
implemented and used in PHP.
See also Array operators
for other ways how to manipulate the arrays.
