Backslash in PHP -- what does it mean?
php
Solution
It's because they're using PHP namespaces. Namespaces are new as of PHP 5.3.
Problem
I just saw the use of a backslash in a reference to a PHP object and was curious about it (I have never seen this before). What does it mean? ``` $mail = new SendGrid\Mail(); ``` If you're curious, here's SendGrid's documentation.
