#28273 [Opn->Bgs]: feof() doesn't return TRUE when invalid file handle is passed to it

ID: 28273 Updated by: abies@php.net Reported By: mikeboulet at newfangled dot com -Status: Open +Status: Bogus Bug Type: Filesystem function related Operating System: Redhat 7.2 or Redhat AS 2.1 PHP Version: 4.3.4 New Comment: Sorry, but your problem does not imply a bug in PHP itself.

Thank you for your interest in PHP. feof() does exactly what it's supposed to. Previous Comments: ------------------------------------------------------------------------ [2004-05-04 15:58:52] mikeboulet at newfangled dot com Description: ------------ When a fopen() is done on a file that has permissions that are set to not allow the current process user to read it or the file doesn't exist it returns false. This is expected. The problem is when feof() is fed the invalid handle it doesn't return TRUE() thus creating an infinite loop in the following code example. Reproduce code: --------------- <?php $fp = fopen( 't.txt', 'r' ); while( !feof( $fp ) ) { print fgets( $fp ); } fclose( $fp ); ?> Expected result: ---------------- feof() would return TRUE to cancel the loop and the script would end. There would of course be warnings because of the invalid file handle, but that is expected. There should be better error handling on the developers part and catch the invalid file handle, but I would expect the file functions to handle this situation accordingly. Actual result: -------------- Inifinite loop ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=28273&edit=1
