Example #1 ReflectionParameter::getType() Usage as of PHP 7.1.0

As of PHP 7.1.0, ReflectionType::__toString() is deprecated, and ReflectionParameter::getType() may return an instance of ReflectionNamedType. To get the name of the parameter type, ReflectionNamedType() is available in this case.

<?php
function someFunction(int $param$param2) {}

$reflectionFunc = new ReflectionFunction('someFunction');
$reflectionParams $reflectionFunc->getParameters();
$reflectionType1 $reflectionParams[0]->getType();
$reflectionType2 $reflectionParams[1]->getType();

assert($reflectionType1 instanceof ReflectionNamedType);
echo 
$reflectionType1->getName(), PHP_EOL;
var_dump($reflectionType2);
?>

Exemplul de mai sus va afișa:

int
NULL

Example #2 ReflectionParameter::getType() Usage before PHP 7.1.0

<?php
function someFunction(int $param$param2) {}

$reflectionFunc = new ReflectionFunction('someFunction');
$reflectionParams $reflectionFunc->getParameters();
$reflectionType1 $reflectionParams[0]->getType();
$reflectionType2 $reflectionParams[1]->getType();

echo 
$reflectionType1PHP_EOL;
var_dump($reflectionType2);
?>

Exemplul de mai sus va afișa în PHP 7.0:

int

As of 7.1, if a parameter type is found then this method returns an instance of ReflectionNamedType (https://www.php.net/manual/en/class.reflectionnamedtype.php), a subclass of ReflectionType.
