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 $reflectionType1, PHP_EOL;
var_dump($reflectionType2);
?>
Exemplul de mai sus va afișa în PHP 7.0:
int NULL
