I wonder how this method decides of is it clonable or not. There is no explanation.
(PHP 5 >= 5.4.0, PHP 7, PHP 8)
ReflectionClass::isCloneable — 返回了一个类是否可复制
返回了这个类是否可复制。
此函数没有参数。
如果这个类可以复制返回 true，否则返回 false。
示例 #1 ReflectionClass::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());
?>以上示例会输出：
bool(false) bool(true)
I wonder how this method decides of is it clonable or not. There is no explanation.similar function:
<?php
function isCloneable(object $obj): bool
{
return !method_exists($obj, '__clone') || is_callable([$obj, '__clone']);
}
?>this method checks is `__clone()` method was declared as privateThis does not work for many of core-classes, just like most other reflection methods.
