Description: ------------ With several objects based upon File_CSV there will be problems in loops with read() and write() calls when they have different configuration (5 vs. 42 fields). Test script: --------------- $csvFile = new File_CSV(); $outFile = new File_CSV(); $csvfileformat = $csvFile->discoverFormat($csvfilename); $csvoutformat = array('fields' => 5, 'sep' => ';', 'quote' => '"'); while ($csv_line = $csvFile->read($csvfilename, $csvfileformat)) { $outarray[] = $csv_line[0]; $outarray[] = $csv_line[1]; $outarray[] = $csv_line[23]; $outarray[] = $csv_line[33]; $outarray[] = $csv_line[43]; $outFile->write($outfilename, $outarray, $csvoutformat); } Bugfix description below. Expected result: ---------------- The first line in the output file will contain 5 fields with the correct value. The second line (after the first call of write() with the other configuration) will only contain the first and second value since read() only reads 5 fields instead of 42. I could fix this problem by changing the file CSV.php like this: 1. Adding "var $config;" after "class File_CSV {" 2. In function "getPointer" I removed "static $config". 3. In "getPointer" I replaced "$config" by "$this->config". (near lines 138 and 148)
