以下示例程序旨在说明PHP中的ReflectionMethod::invoke()函数:
程序_1:
<?php
// Initializing a user-defined class
class Company {
public function GFG($name) {
return 'GeeksforGeeks' . $name;
}
}
// Using ReflectionMethod() over the class Company
$A = new ReflectionMethod('Company', 'GFG');
// Calling the invoke() function
$B = $A->invoke(new Company(),
' is a Computer Science Portal.');
// Getting the result of the invoked method.
echo $B;
?>
输出:
GeeksforGeeks is a Computer Science Portal.
程序_2:
<?php
// Initializing some user-defined classes
class Department1 {
public function hr($name) {
return 'HR' . $name;
}
}
class Department2 {
public function coding($name) {
return 'Coding' . $name;
}
}
class Department3 {
public function marketing($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 invoke() function and
// getting the result of the invoked method.
echo $A->invoke(new Department1(), ' is a Department.');
echo "\n";
echo $B->invoke(new Department2(), ' is also a Department.');
echo "\n";
echo $C->invoke(new Department3(), ' too.');
?>
输出:
