#Frequently Asked questions
The official name is "atoum".
Just send an email to lead@atoum.org to say that you want to contribute to atoum.
Moreover, you should read the CC.md file about coding convention.
The word class is reserved by PHP, so it's not possible to use this name for a class.
In this case, the atoum convention is to prefix name with word php.
There is an english and a french documentation available.
It's a work in progress and you're welcome to improve it.
Moreover, atoum's unit test is the documentation.
You find them in the directory path/to/atoum/tests/units.
Try a php -n atoum.phar in a terminal.
If it works, the problem is in your PHP configuration.
Try to remove ioncube extension, which seems not compatible with atoum.
If you use suhosin, you can also add suhosin.executor.include.whitelist="phar" to your php.ini.
Try to add detect_unicode=0 in your php.ini.
Use only require_once to include atoum.phar in your scripts.
APC is "a free, open, and robust framework for caching and optimizing PHP intermediate code" distributed under the form of a PHP extension.
When testing classes that use APC, you may get some failure messages showing that apc_fetch is unable to retrieve a value.
As all PHP extension, APC has some configuration options to enable it:
apc.enabled: whether to enable or disable APC,apc.enable_cli: whether to enable or disable APC for PHP CLI.
Setting apc.enabled to 1 in your CLI configuration does not do the trick: to avoid these failure messages, you have to set the apc.enable_cli option to 1, otherwise, the extension won't be enabled for the PHP CLI version, which is used by atoum.
These files are used by PHAR to display useful information to the user in CLI, so using markdown in it is a bad idea.
