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

Example:

```
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', '1.1.1.1'),
    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
------------------

[](#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),
));
```
