PHP - Issues

No such file or directory

From Warning: mysqli_connect(): (HY000/2002): No such file or directory:

Message:  No such file or directory
#0 /home/patrick/dev/project/my/mydatabase.php(9): mysqli->__construct()

No such file or directory is actually a failed to connect to database error!

PHPUnit - global variable is null

Error Call to a member function safe_query() on null:

global $database;

To solve the issue, I added the following to site_config.php:

global $database;


site_config.php should not be added to the GIT repository.

This StackOverflow article may help, global variables are null when using PHPUnit
