ReflectionClass::isCloneable()

(PHP 5 >= 5.4.0, PHP 7)

返回了一个类是否可复制

说明

publicReflectionClass::isCloneable(void): bool

返回了这个类是否可复制。

参数

此函数没有参数。

返回值

如果这个类可以复制返回TRUE，否则返回FALSE。

范例

Example #1ReflectionClass::isCloneable()的基本用法

<?php
class NotCloneable {
    public $var1;
    
    private function __clone() {
    }
}
class Cloneable {
    public $var1;
}
$notCloneable = new ReflectionClass('NotCloneable');
$cloneable = new ReflectionClass('Cloneable');
var_dump($notCloneable->isCloneable());
var_dump($cloneable->isCloneable());
?>

以上例程会输出：

bool(false)
bool(true)

I wonder how this method decides of is it clonable or not. There is no explanation.

This does not work for many of core-classes, just like most other reflection methods.
