ID: 41321 Updated by: tony2001@php.net Reported By: marduc at start dot no -Status: Open +Status: Feedback Bug Type: GetImageSize related Operating System: OS X PHP Version: 5.2.2 New Comment: Please try using this CVS snapshot: http://snaps.php.net/php5.2-latest.tar.gz For Windows: http://snaps.php.net/win32/php5.2-win32-latest.zip Previous Comments: ------------------------------------------------------------------------ [2007-05-07 20:56:05] marduc at start dot no Description: ------------ Checking the mime-types of files using getimagesize() produces a warning (Warning: getimagesize() [function.getimagesize]: Read error!) if the file contains less than 12 characters. That is, a file of any extension containing the sequence abcdefghijk gives a warning. Trying to read a file containing the sequence abcdefghijkl gives no warning. This is done on PHP5.2.1. Also tested this on PHP5.1.6, and it seems less than 11 characters gives a warning. Is php trying to read more bytes than available? Reproduce code: --------------- <? /* the directory asdf/ is a directory which apache is the owner of */ exec("touch asdf/asdf"); fwrite(fopen("asdf/asdf", "w"), "abcdefghijk"); $im = getimagesize("asdf/asdf"); ?> Expected result: ---------------- no output, no warning Actual result: -------------- Warning: getimagesize() [function.getimagesize]: Read error! in /Users/torgeir/Sites/test.php on line 4 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41321&edit=1
