Associative Arrays

Associative arrays in PHP are arrays that provide a mapping between keys and values. They are used to store data in the form of key-value pairs, where each key is unique and associated with a specific value.

Creation Syntax


Associative arrays are created using the key operator => to establish the relationship between the key and the value. For example:

php

main

copy
12345
$user = [ "name" => "John", "age" => 30, "city" => "New York" ];

As a result, this code creates an associative array $user with three keys: "name", "age", and "city", and their corresponding values: "John", 30, and "New York". You can access these values using their respective keys:

php

main

copy
123456789
<?php $user = array( "name" => "John", "age" => 30, "city" => "New York" ); echo $user["name"]; // Output "John" ?>
Oppgave
