Can items in PHP associative arrays not be accessed numerically (i.e. by index)?

Question

I\'m trying to understand why, on my page with a query string, the code:

echo \"Item count = \" . count($_GET);
echo \"First item = \" . $_

You can do it this way:

$keys = array_keys($_GET);

echo "First item = " . $_GET[$keys[0]];
