在PHP中将对象转换为字符串 [英] Convert an Object to a String in PHP

问题描述

我想在PHP中将对象转换为字符串.具体来说，我尝试获取mysql查询响应，并尝试将其转换为可以写入文件并稍后使用的内容.

当然，当您尝试将对象写入文件时，PHP会大喊:可捕获的致命错误:无法在..... 中将类DB_result的对象转换为字符串.

或者，如果还有其他方法可以将mysql查询的结果写入文件，则也可以.我正在玩一个自制缓存项目:)

解决方案

也许序列化?它将获取一个对象/数组，并将其转换为字符串(随后可以将其反序列化)

I want to convert an Object into a String in PHP. Specifically, I'm trying to take a mysql query response, and I'm trying to convert it into something I can write to a file and use later.

Of course, when you try to write an Object to a file, PHP appropriately yells: Catchable fatal error: Object of class DB_result could not be converted to string in .....

Alternatively, if there is some other way of writing the result of a mysql query to a file, that works too. I'm playing around with a home-brewed caching project :)

解决方案

Maybe serializing? It will take an object/array and convert it to a string (which can then be un-serialized back later)
