Search Multidimensional Array in PHP

Question

How can I search the following multidimensional array for the string \'uk\'?

array(43)
{
  [0]=> array(1) { [\"country\"]=> string(9) \"Australia\" }
          


        

Answer 1

1) Why are you encapsulating all your simple strings in a new array?

1a) If there actually is a reason:

function my_search($needle, $haystack)
{
    foreach($haystack as $k => $v)
    {
        if ($v["country"] == $needle)
            return $k;
    }
    return FALSE;
}

$key = my_search("uk", $yourArray);
if($key !== FALSE)
{
    ...
} else {
    echo "Not Found.";
}

This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function.

1b) if there isn't:

2) Fix your array using simple strings as values, not array(1)'s of strings

3) If it's fixed, you can simply use array_search()

Edit: Changed arguments to resemble array_search more.
