# ReflectionParameter::getType

(PHP 7)

ReflectionParameter::getType — Gets a parameter's type

### Description

public ReflectionParameter::getType ( ) : ReflectionType

Gets the associated type of a parameter.

### Parameters

This function has no parameters.

### Return Values

Returns a ReflectionType object if a parameter type is specified, `NULL` otherwise.

### Examples

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);
?>`

The above example will output:

    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);
?>`

Output of the above example in PHP 7.0:

    int
    NULL
