Bug #72317 [Opn->Fbk]: tempnam fails with prefix "php"

Edit report at https://bugs.php.net/bug.php?id=72317&edit=1 ID: 72317 Updated by: ab@php.net Reported by: flip101 at gmail dot com Summary: tempnam fails with prefix "php" -Status: Open +Status: Feedback Type: Bug Package: *Directory/Filesystem functions Operating System: Windows 10 64 bits PHP Version: 5.6.20 Block user comment: N Private report: N New Comment: Thanks for the report. Can't reproduce as well. Also it's unlikely an issue with exactly x64 PHP5, as the I/O layer is same. @flip101 does the same happen when using a dir different from temp? For one, could you please post the relevant part of the procmon output when running into this issue? The Process Monitor is fetcheable from sysinternals.com. Thanks.

Anyhow, note[1]: | The x64 builds of PHP 5 for Windows are experimental, I suggest you try with an x86 build of PHP 5.6.22.

I don't see any warnings or notices, exact output at bottom of comment. My exact php version is this one: php-5.6.20-Win32-VC11-x64.zip ==== Script <?php error_reporting(E_ALL); var_dump( file_exists(sys_get_temp_dir()), is_writable(sys_get_temp_dir()), sys_get_temp_dir(), tempnam(sys_get_temp_dir(), 'php'), tempnam(sys_get_temp_dir(), 'aaa') ); ==== End script ==== Console C:\dev>php test.php bool(true) bool(true) string(34) "C:\Users\plagas\AppData\Local\Temp" bool(false) string(46) "C:\Users\plagas\AppData\Local\Temp\aaaE26E.tmp" ==== End Console ------------------------------------------------------------------------ [2016-06-03 12:21:38] cmb@php.net I can't reproduce this issue, neither on Windows 10 x64 with PHP 5.6.22 VC11 x64 Non Thread Safe (2016-May-26 18:22:21), nor on 3v4l.org, see <https://3v4l.org/Wig5o>. Please make sure that you have error_reporting=-E_ALL, and double- check that there are no warnings or notices reported. ------------------------------------------------------------------------ [2016-06-02 15:35:19] flip101 at gmail dot com Description: ------------ Not sure if the "php" prefix is reserved, but if it is, it's not documented at https://secure.php.net/manual/en/function.tempnam.php Note: that i made up the expected results (on line 4), not sure how the random filename algorithm works.
