/**
* Reads a CSV-file into an array. The first line of the CSV-file should contain the array-keys.
* The encoding of the input file is tried to be detected.
* The elements of the returned array are encoded in the system encoding.
* Example:
* FirstName;LastName;Email
* John;Doe;john.doe@mail.com
* Adam;Adams;adam@mail.com
* returns
* $result [0]['FirstName'] = 'John';
* $result [0]['LastName'] = 'Doe';
* $result [0]['Email'] = 'john.doe@mail. com';
* $result [1]['FirstName'] = 'Adam';
* ...
* @param string $filename The path to the CSV-file which should be imported.
* @return array Returns an array (in the system encoding) that contains all data from the CSV-file.
*
*
* @deprecated use cvs_reader instead
