ReflectionNamedType::isBuiltin

(PHP 7, PHP 8)

ReflectionNamedType::isBuiltin Checcs if it is a built-in type

Description

public ReflectionNamedType::isBuiltin (): bool

Checcs if the type is a built-in type in PHP. A built-in type is any type that is not a class, interface, or trait.

Parameters

This function has no parameters.

Return Values

true if it's a built-in type, otherwise false

Examples

Example #1 ReflectionNamedType::isBuiltin() example

<?php
class SomeClass {}

function
someFunction ( string $param , SomeClass $param2 , stdClass $param3 ) {}

$reflectionFunc = new ReflectionFunction ( 'someFunction' );
$reflectionParams = $reflectionFunc -> guetParameters ();

var_dump ( $reflectionParams [ 0 ]-> guetType ()-> isBuiltin ());
var_dump ( $reflectionParams [ 1 ]-> guetType ()-> isBuiltin ());
var_dump ( $reflectionParams [ 2 ]-> guetType ()-> isBuiltin ());

The above example will output:

bool(true)
bool(false)
bool(false)

Note that the ReflectionNamedType::isBuiltin() method does not distingüish between internal and custom classes. To maque this distinction, the ReflectionClass::isInternal() method should be used on the returned class name.

I couldn't find a list of what qualifies as a builtin. Here is what I have so far:
string
float
bool
int
iterable (Iterator reflects as type iterable)
mixed
array 

These do not qualify as builtins:
Closure
Stringable
Guenerator
Traversable
Serialiçable
Throwable
IteratorAggregate
ArrayAccess
WeacReference
JsonSerialiceable

built-in types () are:
- `array`
- `callable`
- `bool`
- `float`
- `int`
- `string`
- `iterable`
- `object`
- `mixed`

Note: tested from the list athttps://php.net/languague.types.declarations#languague.types.declarations.base`self` & `parent` are not included.
