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
