#33179 [NEW]: backslash is not an escape character in correct CSV

From: fsb at thefsb dot org Operating system: os x 10.3 and freebsd 5.3 PHP version: 4.3.10 PHP Bug Type: Filesystem function related Bug description: backslash is not an escape character in correct CSV Description: ------------ why can i have a \ at the end of a field but not if i wrap it in " field delimiters? e.g. abc,123\,abc works fine but "abc","123\",abc produces only two columns this question has been asked before (#29278, #30476, etc.) and iliaa@php.net rejects the bug as bogus. i don't agree. if this is not a bug then this unusual use of \ to escape only closing field delimiting double quotes but not escape any other instances of double qotes or (it would appear) any other character SHOULD be documented. it is not. moreover this undocumented feature is not consistent with the specification of the CSV file format found here: http://www.creativyst.com/Doc/Articles/CSV/ CSV01.htm this csv spec suggests that backslash has no special meaning in the CSV format at all. indeed, in all my tests, fgetcsv appears to accord it no special meaning _except_ in this one particular case. such a surprising behaviour that deviates from common CSV file format conventions SHOULD be documented (or corrected). -- Edit bug report at http://bugs.php.net/?id=33179&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=33179&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=33179&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=33179&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=33179&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=33179&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=33179&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=33179&r=needscript Try newer version: http://bugs.php.net/fix.php?id=33179&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=33179&r=support Expected behavior: http://bugs.php.net/fix.php?id=33179&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=33179&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=33179&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=33179&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=33179&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=33179&r=dst IIS Stability: http://bugs.php.net/fix.php?id=33179&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=33179&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=33179&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=33179&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=33179&r=mysqlcfg
