Question

I have an array with this structure:

Array
(
    [mysite] => Array
        (
            [0] => Array
                (
                    [0] => uniqueid
                    [1] => brand
                    [2] => horsepower
                    [3] => topspeed
                )

            [1] => Array
                (
                    [0] => uniqueid
                    [1] => brand
                    [2] => horsepower
                    [3] => topspeed
                )

            [2] => Array
                (
                    [0] => uniqueid
                    [1] => brand
                    [2] => horsepower
                    [3] => topspeed
                )
        )
)

Every car has an “uniqueid” followed by brand, horsepower, etc.

If I want to get the information for a random car, I do it like this:

$rkey = array_rand($sites['mysite'], 1); // get a random key
$car_info = $myarray['mysite'][$rkey];

Do you have any ideas on how to get information by using a certain “uniqueid”

$car_info = "get the information of a car with a certain uniqueid";

Ty!

try,

Pass unique id inside the for loop you will get the desird result
It may help you,

$array = array(

  0   => Array
            (
                0 => 'uniqueid0',
                1 => 'brand',
                2 => 'horsepower',
                3 => 'topspeed',
            ),
  1   => Array
            (
                0 => 'uniqueid1',
                1 => 'brand',
                2 => 'horsepower',
                3 => 'topspeed',
            ),
  2  => Array
            (
                0 => 'uniqueid2',
                1 => 'brand',
                2 => 'horsepower',
                3 => 'topspeed',
            ),
  3  => Array
            (
                0 => 'uniqueid3',
                1 => 'brand',
                2 => 'horsepower',
                3 => 'topspeed',
            ),
);


  foreach($array as $arr){
    if($arr[0] == 'uniqueid2'){
      $result = $arr;
      break;
    }
  }

print_r($result );

output:

Array ( [0] => uniqueid2 [1] => brand [2] => horsepower [3] => topspeed )
