PHP Associative Arrays
PHP Associative Arrays
Associative arrays are arrays that use named keys that you assign to them.
Example
$car = array("brand"=>"Ford", "model"=>"Mustang", "year"=>1964);
var_dump($car);
Access Associative Arrays
To access an array item you can refer to the key name.
Example
Display the model of the car:
$car = array("brand"=>"Ford", "model"=>"Mustang", "year"=>1964);
echo $car["model"];
Change Value
To change the value of an array item, use the key name:
Example
Change the year item:
$car = array("brand"=>"Ford", "model"=>"Mustang", "year"=>1964);
$car["year"] = 2024;
var_dump($car);
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>";
}
