Description Author

This class can determine the type of files analyzing its contents.

It provides an interface compatible with PHP finfo extension under systems that do not have that PHP extension available.

It takes the path of a file and uses the file command to analyze its contents when possible. Otherwise the class reads the file contents to guess the file type and character encoding.

finfo is an useful PHP extension that makes it possible to determine the type of data contained in files by examining its contents.

Unfortunately the finfo extension is not available in all PHP setups. This class provides a work around by emulating the functionality of the finfo extensionin pure PHP code.
