var_dump() and print_r() output different values

Question

I run this code:

<?php
     $test = $_SERVER['HTTP_HOST'];
     var_dump($test);
     print_r($test);
     die();

I get this output:

I run this code:

<?php
     $test = $_SERVER['HTTP_HOST'];
     print_r($test);
     var_dump($test);
     die();

I get this output:

Why can't print_r() and var_dump() agree on the value of $test in case 1?

For context on how I arrived here. I am running a laravel/homestead vm box, and I'm using Browsersync. Browsersync creates a proxy (localhost:3000) that I connect to, which points to the laravel/homestead vm (192.168.10.10). The proxy changes the value of the Host header when the request passes through it.

This is somewhat impossible I dare say. `var_dump` also doesn't typically output the file and line number. Is your `var_dump` special somehow? — deceze, Jan 19 '17 at 13:57
from what i read, since PHP 5.6.0, if an object implements the method `__debugInfo()`, this will be used to format / modify what will be displayed by `var_dump`. Maybe that can explain what is happening there? — Kaddath, Jan 19 '17 at 14:02

This is an Xdebug bug.

Solution: disable xdebug.

Output with xdebug disabled:
