How to work with Array Functions in PHP

This tutorial will teach you how to define and work with arrays and array functions in PHP

In the given tutorial you will learn how to define and work with arrays and php array functions. Arrays a generally a container which can hold multiple values, unlike a variable where we assign a single value to a single variable. In arrays we can define the limit of index.

Step 1: Structure of an array functions
For array functions php, let's first learn about an array.An array is a data structure that can store one or more values in a single attribute. If a person wants to save multiple values, he will have to make multiple variables to save those multiple values. This is a time consuming and memory wasting approach. A better approach would be to make a single variable and save all the multiple values in this single variable. An array can store multiple values.

Step 2: Kinds of arrays
In PHP, there are types of arrays:
• Numeric Arrays
• Associative Arrays
• Multidimensional Arrays

Step 3: Giving values to a numeric array
In php array functions, Numeric Arrays have numeric indexes and thus can be accessed numericaly in a sequence easily.

Step 4: Giving values to an associative array
Associative arrays have a unique ID associated with them through which they can be accessed.

Step 5: Giving value to a multidimentional array
A multidimensional array is a type of array which contains more than one arrays. These array functions in php can be narrative arrays or associative arrays.
