<h4>Associative_Arrays</h4>
<pre>
<?php
$car = array("brand" => "Ford", "model" => "Mustang", "year" => 1964);
var_dump($car);
?>
</pre>

PHP 4 Loop Through an Associative Array

To loop through and print all the values of an associative array, you could use a foreach loop, like this:

<h4>Loop_Through_an_Associative_Array</h4>
<?php
$car = array("brand"=>"Ford", "model"=>"Mustang", "year"=>1964);

foreach ($car as $x => $y) {
  echo "$x: $y <br>";
}
?>
