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 = \" . $_

Nope -- they are mapped by key value pairs. You can iterate the they KV pair into an indexed array though:

foreach($_GET as $key => $value) {
    $getArray[] = $value;
} 

You can now access the values by index within $getArray.
