ID: 64989 Updated by: larue...@php.net Reported by: vosa at binaryparadise dot com Summary: more accurate return value for readdir() -Status: Open +Status: Not a bug Type: Bug Package: Filesystem function related Operating System: linux PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php return null on argument passing failed is expected and right behavior if you enable E_WARNING report, you will find a warning is threw, like: "PHP Warning: readdir() expects parameter 1 to be resource, string given" Previous Comments: ------------------------------------------------------------------------ [2013-06-07 15:14:23] vosa at binaryparadise dot com Sorry for bad example in original message. Correct one: while(FALSE !== readdir('definitely_not_handler')); ------------------------------------------------------------------------ [2013-06-07 15:08:40] vosa at binaryparadise dot com Description: ------------ --- >From manual page: >http://www.php.net/function.readdir#refsect1-function.readdir-examples --- >From documentation: "Returns the entry name on success or FALSE on failure." >Function returns NULL instead of FALSE in case of bad dir_handler. I think it >should be mentioned in documentation at least. If dir_handler is not exactly resource, then i.e.: "while(FALSE === readdir('definitely_not_handler'));" can end very badly. Test script: --------------- var_dump(readdir('definitely_not_handler')); Expected result: ---------------- FALSE Actual result: -------------- NULL ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64989&edit=1
