#42175 [Opn]: feof() fails to detect the end of file

ID: 42175 User updated by: nikhil dot gupta at in dot ibm dot com Reported By: nikhil dot gupta at in dot ibm dot com Status: Open Bug Type: Filesystem function related Operating System: Linux, Win32-xp PHP Version: 5CVS-2007-08-02 (snap) New Comment: I observed that when I use fgetcsv() to read a file to end, and then check for EOF, feof() returns true. Hence I suspect the problem is with fseek() that although it succceeds in taking the file pointer to EOF but fails to set the EOF flag. Previous Comments: ------------------------------------------------------------------------ [2007-08-02 10:23:45] nikhil dot gupta at in dot ibm dot com Description: ------------ feof() is not able to detect the end of file even when the file pointer is set to EOF using fseek() or any other ways. If we use the sample code similar to that given in the help docs for feof() on php.net: <?php $fh = fopen("file.tmp", "w"); fclose($fh); $fh = fopen("file.tmp", "r"); while(!feof()){ } fclose($fh); unlink("file.tmp"); ?> The code runs to endless loop as feof donot detect the EOF. Reproduce code: --------------- <?php $fh = fopen("file.tmp", "w"); fwrite($fh, "aaa"); fclose($fh); $fh = fopen("file.tmp", "r"); var_dump( ftell($fh) ); var_dump( fseek($fh, 0, SEEK_END) ); var_dump( ftell($fh) ); var_dump( feof($fh) ); fclose($fh); unlink("file.tmp"); ?> Expected result: ---------------- int(0) int(0) int(3) bool(true) Actual result: -------------- int(0) int(0) int(3) bool(false) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=42175&edit=1
