[SOLUTION] search multidimensional array by key and return array value's as result

search multidimensional array by key and return array value's as result

The array (it should not be important what it looks like)

Open in new window

the function:

function search_by_key($key, $array){
  the function.....
}

Open in new window

call the result:

print_r(search_by_key( "item_id", $array));

Open in new window

result:

array of all values searched by key:
Array
(
    [0] => 1435
    [1] => 1412
    [2] => 1412
    [3] => 1391
    [4] => 1411
)

Open in new window

this is just a snippet of the total result's found by key "item_id"

Does someone already have a function?

function search_by_key($key, $array){
the function.....
}

function search($array, $key, $value) { $results = array(); if (is_array($array)) { if (isset($array[$key]) && $array[$key] == $value) $results[] = $array; foreach ($array as $subarray) $results = array_merge($results, search($subarray, $key, $value)); } return $results; }

function search($array, $key) { $results = array(); if (is_array($array)) { if (isset($array[$key])) $results[] = $array[$key]; foreach ($array as $subarray) $results = array_merge($results, search($subarray, $key)); } return $results; } print_r(search($array,"item_id"));exit;

Hello,

There is built in function callde "array_key_exists" you can use it:

bool array_key_exists ( mixed $key , array $search )

For more details see this link:

i am aware of this function, but it does not search in multidimensional array's and it does not return the array values.

array_key_exists("item_id",$array);

will return false. I want the values (in a array) that have the key item_id in any dimension of the array.

Sorry for that. This is the function:

It will return the result in array. See this link:

http://stackoverflow.com/questions/1019076/how-to-search-by-key-value-in-a-multidimensional-array-in-php

almost right. I don't have the value, only the the key.

Here's the modified code to return all values (in a array) within multidimensional array by key.
