Description:
------------
At present, FFI::arrayType() requires that the dimensions be specified as an array of integers. For convenience, it would be nice to have it accept an integer when creating an array with a single dimension. The semantics would be identical to the logic shown below:

class FFI
{
    static function arrayType($type, $dims)
    {
        if (\is_int($dims)) {
            $dims = [$dims];
        }

        // ...
    }
}



Test script:
---------------
$int = \FFI::type('int');

var_dump(\FFI::arrayType($int, [10]));
var_dump(\FFI::arrayType($int, 10));


Expected result:
----------------
object(FFI\CType:int32_t[10])#2 (0) {
}
object(FFI\CType:int32_t[10])#3 (0) {
}

Actual result:
--------------
object(FFI\CType:int32_t[10])#2 (0) {
}
FFI::arrayType() expects parameter 2 to be array, int given in ...
