(before write and after) I didn't store it in a variable. it should be read the new filesize, so I thought it is a bug that still use the old one. ------------------------------------------------------------------------ [2016-08-23 10:53:31] cmb@php.net 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 The bug is rather in your script. You're reading the file size, and writing this (increased by one) back to the file. Then you expect the file size to have increased. ------------------------------------------------------------------------ [2016-08-23 10:36:53] frank123m at gmail dot com Description: ------------ function hit_count() { $filename = 'count.txt'; $handle = fopen($filename, 'r'); $current = fread($handle, filesize($filename)); fclose($handle); $current_inc = $current + 1; $handle = fopen($filename, 'w'); fwrite($handle, $current_inc); fclose($handle); $handle = fopen($filename, 'r'); $current = fread($handle, filesize($filename)); fclose($handle); echo $current; } Test script: --------------- count.txt: example: 99->100 echo $current will show 10 instead of 100. filesize($filename) remain the same after fwrite. its the bug. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72930&edit=1
