如何序列化在属性中有闭包的对象？ [英] How to serialize object that has closures inside properties?

问题描述

如果我做 serialize（$ obj），我得到：

不允许序列化Closure

Serialization of 'Closure' is not allowed

有没有什么方法可以在序列化时忽略这些闭包？我不需要它们，当我反序列化字符串反正（这些属性的值可以为null或任何）。

Is there any way these closures can be ignored when serializing? I don't need them when I unserialize the string anyway (value of those properties can be null or whatever).

我的类看起来像这样：

Class Node{

  protected $attrs = array();

}

$ attrs 是一个关联数组，可以包含一些元素是闭包，如
$ attrs ['validator'] = function（）{...}

$attrs is an associative array that can contain some elements that are closures, like $attrs['validator'] = function(){...}

推荐答案

我写了一个函数，允许任何异常序列化。

I've written a function that allows any Exception to be serialized. This is done by flattening complex values in the backtrace.

<?php
try {
    // exception gets thrown here, i.e.
    // throw new Exception(); 
} catch (Exception $exception) {
    flattenExceptionBacktrace($exception);
    $serialized = serialize($exception);

    $unserialized = unserialize($serialized);
    print_r($unserialized->getTraceAsString());
}
