Question

I have a multi-dimension array like:

$fields = 
    Array (
        [1] => Array
            (
                [field_special_features5_value] => Special Function 5
            )

        [2] => Array
            (
                [field_special_features6_value] => Special Function 6
            )

        [3] => Array
            (
                [field_opticalzoom_value] => Optical Zoom
            )
    )

I want to get the value by key, I tried the code below but not work

$tmp = array_search('field_special_features5_value' , $fields);
echo $tmp;

How can I get the value Special Function 5 of the key field_special_features5_value?

Thanks

print $fields[1]['field_special_features5_value'];

or if you don’t know at which index your array is, something like this:

function GetKey($key, $search)
{
    foreach ($search as $array)
    {
        if (array_key_exists($key, $array))
        {
            return $array[$key];
        }
    }

    return false;
}

$tmp = GetKey('field_special_features5_value' , $fields);
echo $tmp;
