7 system.api.php hook_archiver_info()

Declare archivers to the system.

An archiver is a class that is able to package and unpackage one or more files into a single possibly compressed file. Common examples of such files are zip files and tar.gz files. All archiver classes must implement ArchiverInterface.

Each entry should be keyed on a unique value, and specify three additional keys:

  • class: The name of the PHP class for this archiver.
  • extensions: An array of file extensions that this archiver supports.
  • weight: This optional key specifies the weight of this archiver. When mapping file extensions to archivers, the first archiver by weight found that supports the requested extension will be used.
