The ReflectionParameter::getType() function is an inbuilt function in PHP which is used to return the type of the specified parameter.

Syntax:

ReflectionType ReflectionParameter::getType ( void )

Parameters: This function does not accept any parameters.

Return Value: This function returns the type of the specified parameter.

Below programs illustrate the ReflectionParameter::getType() function in PHP:



Program 1:




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

Output:

int

Program 2:




<?php
   
// Initializing some user-defined classes
class Department1
{
    protected function HR(float $Parameter1){}
}
class Department2
{
    final function Coding( Exception $Parameter2,
                Exception $Parameter3){}
}
class Department3
{
    function Marketing( sting $Parameter4,
           string $Parameter5, string $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 getType() function and 
// getting the type of the specified parameter
echo $A->getType();
echo "\n";
echo $B->getType();
echo "\n";
echo $C->getType();
?>
Output:
