[RESOLVED] xD Arrays and searching for keys

[Kudose]

Could someone please fill me in on why

$_locations = array(
            0 => array('city' => 'Hell', 'prov' => 'Michigan', 'country' => 'USA'),
            1 => array('city' => 'Kansas City', 'prov' => 'Kansas', 'country' => 'USA'), 
            2 => array('city' => 'Chicago', 'prov' => 'Illinois', 'country' => 'USA')
          );
$key = 0;
if(in_array($key, $_locations)) echo 1; else echo 2;
echo '<br />';
if(array_key_exists($key, $_locations)) echo 1; else echo 2;

in_array fails?

I would think that 0 is "in the $_locations array" since it is slot 1.

[man]in_array/man fails because there is no value in the $_locations array equal to 0.

That's why there is an [man]in_array[/man] function and an [man]array_key_exists[/man] function 🙂

There is my answer ... no value, not key, equal to 0.

Thanks.
