PHP Associative Arrays


PHP Associative Arrays

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

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:

Example

Display all array items, keys and values:

$car = array("brand"=>"Ford", "model"=>"Mustang", "year"=>1964);

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