PHP Associative Arrays Tutorial

PHP associative arrays allow you to access the values in the array through the use of named string ID keys for each stored value.

There are 2 different ways of creating arrays.

Example 1:

<?php
$salaries = array("Angel"=>2000, "Billy"=>3000, "Charles"=>4000);

echo "Angle makes - $" . $salaries["Angel"] . " a month.<br />";
echo "Billy makes - $" . $salaries["Billy"] . " a month.<br />";
echo "Charles makes - $" . $salaries["Charles"] . " a month.";
?>

The code above outputs:

Angle makes - $2000 a month.
Billy makes - $3000 a month.
Charles makes - $4000 a month.

Example 2:

<?php
$salaries['Angel'] = "2000";
$salaries['Billy'] = "3000";
$salaries['Charles'] = "4000";

echo "Angle makes - $" . $salaries["Angel"] . " a month.<br />";
echo "Billy makes - $" . $salaries["Billy"] . " a month.<br />";
echo "Charles makes - $" . $salaries["Charles"] . " a month.";
?>

The code above outputs:

Angle makes - $2000 a month.
Billy makes - $3000 a month.
Charles makes - $4000 a month.
