Casting an Array with Numeric Keys as an Object

I was wondering about (object) type casting.

It's possible to do a lot of useful things, like converting an associative array to an object, and some not so useful and a bit funny (IMHO) things, like converting a scalar value to object.

But how can I access the result of casting of an indexed array?

// Converting to object an indexed array
$obj = (object) array( 'apple', 'fruit' );

How about accessing a specific value? 

print $obj[0];      // Fatal error & doesn't have and any sense
print $obj->scalar[0];  // Any sense
print $obj->0;      // Syntax error
print $obj->${'0'};     // Fatal error: empty property.   
print_r( get_object_vars( $obj ) ); // Returns Array()

print_r( $obj );    /* Returns
                    stdClass Object
                     (
                            [0] => apple
                            [1] => fruit
                     )
                    */

The following works because stdClass implements dynamically Countable and ArrayAccess:

foreach( $obj as $k => $v ) {
    print $k . ' => ' . $v . PHP_EOL;
}
php casting
