How to make an array in php

Learn how to create an array in PHP with an example: create, access, add and remove elements from an array.

Creating an Array in PHP

An array is a data structure in PHP which allows you to store multiple values in a single variable. This makes it easier to work with data since you can access, add, remove and manipulate the values in a single place.

In order to create an array, you need to use the array() function which takes a list of values. The values can be of any type, including strings, numbers, objects, or even other arrays. The syntax for creating an array is as follows:

$arr = array(value1, value2, value3, ...);

For example, if you wanted to create an array of numbers from 0 to 9, you could use the following code:

$numbers = array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9);

You can also create an associative array, which is an array where each element is associated with a key. The syntax for creating an associative array is as follows:

$arr = array("key1" => value1, "key2" => value2, "key3" => value3, ...);

For example, if you wanted to create an associative array of student names and their respective grades, you could use the following code:

$grades = array("John" => "A", "Jane" => "B", "Bob" => "C", "Sally" => "D");

You can also add elements to an existing array using the array_push() function. The syntax for adding an element to an array is as follows:

array_push($arr, value);

For example, if you wanted to add a new student to the array we created above, you could use the following code:

array_push($grades, "Nick" => "A");

You can also remove elements from an array using the array_pop() function. The syntax for removing an element from an array is as follows:

array_pop($arr);

For example, if you wanted to remove the student "Bob" from the array we created above, you could use the following code:

array_pop($grades, "Bob");

These are just a few of the ways you can create, add, and remove elements from an array in PHP. For more information, you can refer to the official documentation here.
