using array_search for multi dimensional array

Question

using array_search in a 1 dimensional array is simple

$array = array("apple", "banana", "cherry"); $searchValue = "cherry"; $key = array_search($searchValue, $array);  echo $key; 

but how about an multi dimensional array?

    #RaceRecord      [CarID] [ColorID] [Position] [0]    1        1         3 [1]    2        1         1 [2]    3        2         4 [3]    4        2         2 [4]    5        3         5 

for example i want to get the index of the car whose position is 1. How do i do this?

Answer 1

In php 5.5.5 & later versions, you can try this

$array_subjected_to_search =array( array(         'name' => 'flash',         'type' => 'hero'     ),  array(         'name' => 'zoom',         'type' => 'villian'     ),  array(         'name' => 'snart',         'type' => 'antihero'     ) ); $key = array_search('snart', array_column($array_subjected_to_search, 'name')); var_dump($array_subjected_to_search[$key]); 

Output:

array(2) { ["name"]=> string(5) "snart" ["type"]=> string(8) "antihero" }

Answer 2

function find_car_with_position($cars, $position) {     foreach($cars as $index => $car) {         if($car['Position'] == $position) return $index;     }     return FALSE; }
