$GLOBALS['my']['dca']['my_field3'] = 'value 3';

Namespace and key name patterns

Compromise the $GLOBALS array directly is no good idea at all. You can use a custom namespace, which define a path inside of the $GLOBALS array. Each namespace part is separated by /, e.g. my/dca which will be decoded to $GLOBALS['my']['dca'].

Also you may want to filter properties by their name, this is useful if the provider share a namespace with another php globals config file provider. The pattern allow you to filter accepted property names. For example my_* will only accept and store properties that starts with my_. Wildcards are allowed through fnmatch.

Save mode

The data provider has two generation modes.

In diff mode it will read the state before including the config file. This state is supposed as the "default" state. When generating the php file, only values that differ from the "default" view will be included.

In all mode all properties will be stored, regardless of the previous state.

As developer you must respect, that the diff mode only work, if you not include the php file by yourself. The php file will be automatically loaded through require in the loading process. In all mode the php will also be loaded, by through require_once.
