Hello,
There is built in function callde "array_key_exists" you can use it:
For more details see this link:
There is built in function callde "array_key_exists" you can use it:
bool array_key_exists ( mixed $key , array $search )
For more details see this link:
http://php.net/manual/en/function.array-key-exists.php
i am aware of this function, but it does not search in multidimensional array's and it does not return the array values.
array_key_exists("item_id"
will return false. I want the values (in a array) that have the key item_id in any dimension of the array.
array_key_exists("item_id"
will return false. I want the values (in a array) that have the key item_id in any dimension of the array.
Sorry for that. This is the function:
It will return the result in array. See this link:
function search($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;
}
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.

}
return $results;
}
print_r(search($array,"item_id"));exit;
