    It is used in case of associative array,in these type of array each ID key is associated with a value.

    For eg if you want to store price of cars in an array then it will be good idea to store it in this way

    $car=array("Maruti"=>200000,"BMW"=>"100000");
    foreach ($a as $key => $v) {
    echo $car[$key];
    }
