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:
main.php
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:
main.php
123456789<?php $user = array( "name" => "John", "age" => 30, "city" => "New York" ); echo $user["name"]; // Output "John" ?>
Swipe to start coding
Fill in the blanks in the code to create an associative array $person with three key-value pairs (e.g., 'name' => 'John', 'age' => 25, 'profession' => 'Engineer'). Then, access the value by the key 'name' and print it to the screen.
