note 105110 added to function.fputcsv

Unexpected (to me) behaviour: the enclosure characters inside the strings are doubled *unless* they're preceded by a backslash. If the enclosure is preceded by a backslash it's considered to be already escaped. <?php $data = array( 'Doubled: -> " <-', 'NOT doubled: -> \" <-', ); $buffer = fopen('php://temp', 'r+'); fputcsv($buffer, $data); rewind($buffer); $csv = fgets($buffer); fclose($buffer); echo $csv; // "Doubled: -> "" <-","NOT doubled: -> \" <-" ?> As a result, the CSV file generated by my application was not correctly opened by OpenOffice.org. The offending row and all the subsequent rows were missing from the spreadsheet.
