Below programs illustrate the ReflectionMethod::getClosure() function in PHP:
Program_1:
PHP
<?php// Initializing a user-defined classclass Company { protected function neveropen($name) { return 'GFG' . $name; }}// Using ReflectionMethod() over the class Company$A = new ReflectionMethod('Company', 'neveropen');// Calling the getClosure() function$B = $A->getClosure(new Company());// Getting a dynamically created closure// for the method otherwise, return NULL// in case of an error.var_dump($B);?> |
Output:
object(Closure)#3 (2) {
["this"]=>
object(Company)#2 (0) {
}
["parameter"]=>
array(1) {
["$name"]=>
string(10) "<required>"
}
}
Program_2:
PHP
<?php // Initializing some user-defined classesclass Department1 { protected function HR($name) { return 'hr' . $name; }}class Department2 { protected function Coding($name) { return 'coding' . $name; }}class Department3 { protected function Marketing($name) { return 'marketing' . $name; }} // Using ReflectionMethod() over the above classes$A = new ReflectionMethod('Department1', 'HR');$B = new ReflectionMethod('Department2', 'Coding');$C = new ReflectionMethod('Department3', 'Marketing'); // Calling the getClosure() function and // Getting a dynamically created closure// for the method otherwise, return NULL// in case of an error.var_dump($A->getClosure(new Department1()));var_dump($B->getClosure(new Department2()));var_dump($C->getClosure(new Department3()));?> |
Output:
object(Closure)#5 (2) {
["this"]=>
object(Department1)#4 (0) {
}
["parameter"]=>
array(1) {
["$name"]=>
string(10) "<required>"
}
}
object(Closure)#4 (2) {
["this"]=>
object(Department2)#5 (0) {
}
["parameter"]=>
array(1) {
["$name"]=>
string(10) "<required>"
}
}
object(Closure)#5 (2) {
["this"]=>
