如何将var_dump的结果捕获到字符串? [英] How can I capture the result of var_dump to a string?

问题描述

我想捕获 var_dump 字符串.

I'd like to capture the output of var_dump to a string.

PHP文档说；

与将结果直接输出到浏览器的任何内容一样， output-control函数可用于捕获此函数的输出，并将其保存在字符串中(例如).

As with anything that outputs its result directly to the browser, the output-control functions can be used to capture the output of this function, and save it in a string (for example).

这可能是一个如何工作的例子?

What would be an example of how that might work?

print_r()的可能性不大，因为它不会给我所需的信息.

print_r() isn't a valid possibility, because it's not going to give me the information that I need.

推荐答案

使用输出缓冲:

<?php
ob_start();
var_dump($someVar);
$result = ob_get_clean();
?>
