Write a PHP program to demonstrate the use of array.​

Introduction​

Arrays are essential data structures in programming and are widely used to store structured data. With an array, it is possible to store multiple variables with the same data type in a single collection. In PHP, array can contain both strings and integer, as well as mix of the two types.

In this article, we will take a look at how to use array in PHP programming and some of their commonly used functions and operators. We will also provide example codes to explain the concept and discuss some real-world examples on how array can be used.

Prerequisites​

In order to understand the concepts discussed in this article, users should have basic understanding about variables, strings, and data types.

Best Recommendations​

When using arrays in PHP, it is important to use consistent naming conventions. This will greatly reduce the confusion when dealing with complex array structures. Additionally, try to avoid defining extremely large or complex array structures, as they could affect the performance of your application.

Code​

<?php
    // Declaring an array in PHP
    $myArray = array("apple", "banana", "cucumber");

    // Adding elements to an array
    array_push($myArray, "grape");

    // Retrieving elements from an array
    // This line of code will print an orange
    echo $myArray[3];
?>

Output​

grape
Explanation

The code above showcases the basic usage of an array in PHP. Firstly, an array is declared and initialized with three elements. Then, an element is added to the array with array_push(). Finally, an element from the array is retrieved with its index.
