Patch applied to PHP 5.5.4-pl0-gentoo Previous Comments: ------------------------------------------------------------------------ [2013-11-05 13:41:59] laruence@php.net a patch is attached to explain where the problems come from. anyway maybe a better fix is clean the stat in getcsv. ------------------------------------------------------------------------ [2013-11-05 13:40:38] laruence@php.net The following patch has been added/updated: Patch Name: bug65947.patch Revision: 1383658838 URL: https://bugs.php.net/patch-display.php?bug=65947&patch=bug65947.patch&revision=1383658838 ------------------------------------------------------------------------ [2013-11-05 10:31:29] remi dot sauvat+php at inetprocess dot com I have the same issue on Gentoo OS. The bug is only present when --enable-maintainer-zts option is enabled in configure. (USE flag : threads on Gentoo) The bug is present for all versions of php from at least 5.2 to 5.5 when local is set to UTF-8 and reading ISO-8859 csv data. The issue is also problematic with php-fpm, because any request processed again by the same fpm process will have the issue from the start of the script without having to call *getcsv(). The only way to make it work again is to kill the fpm process. Here is another code example with str_getcsv. Test code : -------------- <?php $filename = 'test.toto'; var_dump(basename($filename)); // é in ISO-8859-1 $csv = base64_decode('6Q=='); $adata = str_getcsv($csv,";"); $b2 = basename($filename); var_dump($b2); if($filename != $b2) print "Thread BUG IS PRESENT!!!!\n"; Expected results with php-fpm: ------------- # 1st request : string(8) "test.txt" string(8) "test.txt" # 2nd request : string(8) "test.txt" string(8) "test.txt" Actual results : ----------------- # 1st request : string(8) "test.txt" string(0) "" Thread BUG IS PRESENT!!!! # 2nd request : string(0) "" string(0) "" Thread BUG IS PRESENT!!!! ------------------------------------------------------------------------ [2013-10-22 14:10:52] phpbugs at dev dot bitadept dot org Description: ------------ Calls to basename and pathinfo are no more working after using fgetcsv. This is the case when the system's locale is set to utf8 an you try to parse a file using fgetcsv that is encoding in iso8859-1 and contains some german Umlaute. Setting the locale to iso8859-1 in the first place is fixing the problem, but this should not happen at all.
