#36476 [NEW]: fwrite count by 2 with img src=""

From: mdulay at millersville dot edu Operating system: Solaris 10/ HPUX 11 PHP version: 5.1.2 PHP Bug Type: Filesystem function related Bug description: fwrite count by 2 with img src="" Description: ------------ The issue occurs on both PHP4 and PHP5 and on 2 different OS, HPUX 11 and Solaris 10. I have a simple counter that reads a file adds 1 and rewrites the file. After a good bit of frustration I found that there was a missing img src="" in the HTML. It didn't matter where the PHP was whether it preceeded the HTML or was inline, the counter still added 2 each time it was called upon. Of course I have fixed the HTML, however the tie between a missing image and the PHP has me perplexed. The code I have attached has been simplified the situation however the initial code was using includes and the missing image was not easily detected. Reproduce code: --------------- <? $counterfile="count.txt"; $conn=fopen($counterfile,'r'); $count=trim(fgets($conn)); echo ":".$count.":"; ++$count; fclose($conn); $conn=fopen($counterfile,'w'); fwrite($conn,$count); fclose($conn); echo ":".$count.":"; ?> <html> <body> <img src="" > </body> </html> Expected result: ---------------- A missing image with a counter that increments by 1. Actual result: -------------- Counter that has incremented by 2 and a missing image. -- Edit bug report at http://bugs.php.net/?id=36476&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=36476&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=36476&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=36476&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=36476&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=36476&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=36476&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=36476&r=needscript Try newer version: http://bugs.php.net/fix.php?id=36476&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=36476&r=support Expected behavior: http://bugs.php.net/fix.php?id=36476&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=36476&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=36476&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=36476&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=36476&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=36476&r=dst IIS Stability: http://bugs.php.net/fix.php?id=36476&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=36476&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=36476&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=36476&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=36476&r=mysqlcfg
