PHPExcel IOFactory_reader command

Apr 19, 2012 at 3:15 AM

Hi there,

I want to read csv file with php excel but I have found that in IOFactory.php in $reader there is nothing for case 'csv' and its written that    

// We must not try to use CSV reader since it loads
                    // all files including Excel files etc.


I dont have any problem in reading the csv file but why there is such a command in this class?
