require（）给我一个错误，因为Firefox正在跳过目录

Question

This code works in every browser except Firefox and I can't seem to find out why. I have tried to require all the way back to the root dir, but it still throws me the error:

"Fatal error: require(): Failed opening required 'PHPMailer/src/PHPMailer.php' (include_path='.:/opt/cpanel/ea-php70/root/usr/share/pear')"

require 'PHPMailer/src/PHPMailer.php';
require 'PHPMailer/src/SMTP.php';
require 'PHPMailer/src/Exception.php';

Answer 1

Your browser has no influence over how paths work on your server.

Most simply, you do not have the correct path in your require statement.

However, I would recommend using composer and its autoload script to bring PHPMailer into your project.
