ReflectionMethod::getPrototype()函数是PHP中的内置函数,用于返回指定方法的原型,否则,如果该方法没有原型,则返回异常/错误。
用法:
ReflectionMethod ReflectionMethod::getPrototype( void )
参数:该函数不接受任何参数。
返回值:该函数返回指定方法的原型,否则,如果该方法没有原型,则返回异常/错误。
以下示例程序旨在说明PHP中的ReflectionMethod::getPrototype()函数:
程序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);
?>
输出:
object(ReflectionMethod)#2 (2) { ["name"]=> string(13) "Marketing_Dpt" ["class"]=> string(11) "Department1" }
程序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);
?>
输出:方法没有任何原型,它将给您一个错误。
PHP Fatal error:Uncaught ReflectionException:Method Company:: GeeksforGeeks does not have a prototype in /home/9d8367b263ee4d7ec6941876b0eae792.php:15 Stack trace: #0 /home/9d8367b263ee4d7ec6941876b0eae792.php(15): ReflectionMethod->getPrototype() #1 {main} thrown in /home/9d8367b263ee4d7ec6941876b0eae792.php on line 15
