Backup/restore environment variables: globals, static vars, configs
Open Issues: 0
Backup/restore environment variables: globals and static vars. This is very useful for initializing environment for a test. Keep the current state of the environment from interfering with other tests.
You can add "Parameters" to the environment, each "applying" and "restoring" a specific super global or static property of a class, you can even keep a precice state of the filesystem.
GlobalParam- used for setting / restoring '_POST', '_GET', '_FILES', '_SERVER', '_COOKIE' and '_SESSION'
ServerParam- used specifically for '_SERVER' super global so you can set / restore only some of its contents, e.g. REMOTE_HOST', 'CLIENT_IP ...
StaticParam- used for setting / restoring static properties of classes, it can handle protected and private ones too.
FileParam- used for setting / restoring files and their contents. Ensures a certain file and its content are present, and restore previous state
DirectoryParam- used for setting / restoring a whole dir with all of its contents. Ensures a certain dir and its content are present, and restore previous state
use CL\EnvBackup\Env; use CL\EnvBackup\GlobalParam; use CL\EnvBackup\ServerParam; use CL\EnvBackup\StaticParam; $env = new Env(array( new GlobalParam('_POST', array('new post name' => 'val')), new ServerParam('REMOTE_ADDR', '18.104.22.168'), new StaticParam('MyClass', 'private_var', 10) new FileParam('/path/to/file', 'file content') new DirectoryParam('/path/to/dir', array( 'file1.txt' => 'file contents', 'inner_dir' => array( 'inner_file1.csv' => 'a, b', 'inner_file2.txt' => 'test', ) )) )); $env->apply(); // Do some stuff that changes / uses these variables // ... $env->restore();
ServerParam in CLI
In CLI environment, $_SERVER variables are very different than if the script is run by apache or cgi. If you want to use env-backup in such an environment, you can pass ServerParam::CLI like this:
$env = new Env(array( new ServerParam('HOME', '/test/home', ServerParam::CLI), new ServerParam('argc', 4, ServerParam::CLI), ));
