如何将 var 转储的结果捕获到字符串？

Question

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

The PHP docs say;

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).

Can someone give me an example of how that might work?

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

Use output buffering:

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