The ReflectionParameter::getClass() function is an inbuilt function in PHP which is used to return the class type hinted for the parameter.

Syntax:

ReflectionClass ReflectionParameter::getClass ( void )

Parameters: This function does not accept any parameter.

Return Value: This function returns the class type hinted for the parameter.

Below programs illustrate the ReflectionParameter::getClass() function in PHP:
Program 1:




<?php
  
// Initializing a user-defined class Company1
class Company1
{
    public function GFG( Exception $Parameter){}
}
  
// Initializing a subclass Company2
class Company2 extends Company1
{
}
  
// Using the ReflectionParameter over the above class
$A = new ReflectionParameter(['Company2', 'GFG'], 0); 
  
// Calling the getClass() function
$B = $A->getClass();
  
// Getting the class type hinted for the parameter.
var_dump($B);
?>


Output:

object(ReflectionClass)#2 (1) {
  ["name"]=>
  string(9) "Exception"
}

Program 2:




<?php
  
// Initializing some user-defined classes
class Department1
{
    public function HR($Parameter1){}
}
class Department2
{
    public function Coding( Exception $Parameter2, Exception $Parameter3){}
}
class Department3
{
    public function Marketing($Parameter4, $Parameter5, $Parameter6){}
}
  
// Using the ReflectionParameter over the above classes
$A = new ReflectionParameter(['Department1', 'HR'], 0);
$B = new ReflectionParameter(['Department2', 'Coding'], 1);
$C = new ReflectionParameter(['Department3', 'Marketing'], 2);
  
// Calling the getClass() function and
// getting the class type hinted for the parameter.
var_dump($A->getClass());
var_dump($B->getClass());
var_dump($C->getClass());
?>


Output:

NULL
object(ReflectionClass)#4 (1) {
  ["name"]=>
  string(9) "Exception"
}
NULL
