Description:
------------
There is a difference in results.
ReflectionParameter getType() function returns "int".
But builtin function "gettype" returns "integer".
Just check the test script below.

Test script:
---------------
class A {
    function f(int $a) {}
}
$r = new ReflectionClass("A");
$m = $r->getMethods();
$p = $m[0]->getParameters();
$t = $p[0]->getType();

echo $t; // "int"

echo PHP_EOL;

echo gettype(42); // "integer"

Expected result:
----------------
In both cases should return "integer"

Actual result:
--------------
ReflectionParameter returns "int" and gettype() returns "integer"

This as an inconsistency issue. Please stick to one only variant: "int" XOR "integer". Using both variants is ambiguous.

The values returned by gettype() ar#e unlikely to be ever changed
for backward compatibility reasons.  In PHP 8 the new function
get_debug_type()[1] will be available, which returns "int".

If you strongly feel that the return values of gettype() should be
changed, feel free to pursue the RFC process[2].  For the time
being, I'm suspending this ticket.

Maybe it would be easier just to change the reported type in "ReflectionParameter" instead of changing it the function "gettype()"?

oh, i see function/method typehint can be literally anything. Something like this would be hard to check and compare - "getType()" (ReflectionParameter) results with "gettype()" builtin function:

function foo(int $i, string $s, Foo $foo, Bar\Baz $barbaz) {
  ...
}

int
string
Foo
Bar\Baz

Besides that this would be a BC break the other way round, "int"
is the canonical type name, and "integer" is an alias for BC
reasons.
