The ReflectionMethod::getPrototype() function is an inbuilt function in PHP which is used to return the prototype of the specified method otherwise, an exception/error is returned if the method does not have a prototype.
Syntax:
ReflectionMethod ReflectionMethod::getPrototype( void )
Parameters: This function does not accept any parameter.
Return Value: This function returns the prototype of the specified method otherwise, an exception/error is returned if the method does not have a prototype.
Below programs illustrate the ReflectionMethod::getPrototype() function in PHP:
Program 1:
<?php // Initializing a user-defined class Department1 class Department1 {
public function Marketing_Dpt() {
return 'Department1' ;
}
} // Initializing a subclass of the above class Department1 class Department2 extends Department1{
public function Marketing_Dpt() {
return 'Department2' ;
}
} // Again Initializing a subclass of the above subclass Department2 class Department3 extends Department2{
public function Coding_Dpt() {
return 'Department3' ;
}
} // Using the ReflectionMethod() over the above // subclass Department2 $A = new ReflectionMethod( 'Department3' , 'Marketing_Dpt' );
// Calling the getPrototype() function $B = $A ->getPrototype();
// Getting the prototype var_dump( $B );
?> |
Output:
object(ReflectionMethod)#2 (2) { ["name"]=> string(13) "Marketing_Dpt" ["class"]=> string(11) "Department1" }
Program 2:
<?php // Initializing a user-defined class class Company {
protected function GeeksforGeeks( $name ) {
return 'GFG' . $name ;
}
} // Using ReflectionMethod() over the class Company $A = new ReflectionMethod( 'Company' , 'GeeksforGeeks' );
// Calling the getPrototype() function $B = $A ->getPrototype();
// Getting the prototype or an error is returned // if the method does not have a prototype. var_dump( $B );
?> |
Output: Method does not have any prototype that will give you an error.
