ReflectionMethod::invoke()函數是PHP中的內置函數,用於調用指定的反射方法並返回方法的結果。
用法:
public mixed ReflectionMethod::invoke ( $object, $parameter )
參數:此函數接受兩個參數,如下所示:
- object:這是初始化的類對象。
- parameter:這是要傳遞給該方法的零個或多個參數。
返回值:該函數返回被調用方法的結果。
以下示例程序旨在說明PHP中的ReflectionMethod::invoke()函數:
程序_1:
<?php
// Initializing a user-defined class
class Company {
public function GFG($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 $B;
?>
輸出:
GeeksforGeeks is a Computer Science Portal.
程序_2:
<?php
// Initializing some user-defined classes
class Department1 {
public function hr($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.');
?>
輸出:
HR is a Department. Coding is also a Department. Marketing too.
