Associative Array in PHP

In this tutorial we will learn about Associative Array in PHP. The associative arrays are very similar to numeric arrays in term of functionality but they are different in terms of their index. Associative array will have their index as string, so that you can establish a strong association between key and values.

Associative arrays are arrays that use named keys that you assign to them.

NOTE − don’t keep associative array inside double quote while printing otherwise it would not return any value.

Create Associative Array

There are two ways to create an associative array:

$age = array(“Peter”=>”35”, “Ben”=>”37”);

or:

$age[‘Peter’] = “35”;

$age[‘Ben’] = “37”;

so these are two ways to create indexes array , so code for first method is here.

<?php

$age = array(“Peter”=>”35”, “Ben”=>”37”, “Joe”=>”43”);

echo “Peter is ” . $age[‘Peter’] . ” years old.”;

?>

Output: Peter is 35 years old.
