[PHP-BUG] Bug #65492 [NEW]: Seeking beyond EOF leads to inconsistent results for key() and current()
From: foo at example dot com Operating system: any PHP version: Irrelevant Package: SPL related Bug Type: Bug Bug description:Seeking beyond EOF leads to inconsistent results for key() and current() Description: When seek()'ing beyond the end of file in an SplFileObject, SplFileObject::key() will return the number of the last line in the file but SplFileObject::current() will return false. This is inconsistent. Either SplFileObject::current() returns the content of the last line then, too. Or SplFileObject::key() should return false as well. As an alternative, SplFileObject::seek() could raise an OutOfBoundsException when trying to seek beyond EOF. Test script: --- $txt = <<< TXT foo bar baz TXT; $file = new SplTempFileObject(-1); $file->fwrite($txt); $file->seek(100); var_dump( $file->key(), $file->fgetcsv()); Expected result: int(2) baz or false false or OutOfBoundsException Actual result: -- int(2) NULL -- Edit bug report at https://bugs.php.net/bug.php?id=65492&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=65492&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=65492&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=65492&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=65492&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=65492&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=65492&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=65492&r=needscript Try newer version: https://bugs.php.net/fix.php?id=65492&r=oldversion Not developer issue:https://bugs.php.net/fix.php?id=65492&r=support Expected behavior: https://bugs.php.net/fix.php?id=65492&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=65492&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=65492&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=65492&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=65492&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=65492&r=dst IIS Stability: https://bugs.php.net/fix.php?id=65492&r=isapi Install GNU Sed:https://bugs.php.net/fix.php?id=65492&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=65492&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=65492&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=65492&r=mysqlcfg
Bug #65492 [Opn]: Seeking beyond EOF leads to inconsistent results for key() and current()
Edit report at https://bugs.php.net/bug.php?id=65492&edit=1 ID: 65492 User updated by: foo at example dot com Reported by: foo at example dot com Summary:Seeking beyond EOF leads to inconsistent results for key() and current() Status: Open Type: Bug Package:SPL related Operating System: any PHP Version:Irrelevant Block user comment: N Private report: N New Comment: Sorry, the last line in the Test Script should read var_dump( $file->key(), $file->current() ); The problem does exist for fgetcsv() though, too. It will return NULL instead of the data at the last line.
