Ok, here is the detailed problem: If tempnam() will be called with an empty string, expand_filepath() (called from php_check_specific_open_basedir()) will expand this string to cwd. The cwd is most probably in open_basedir, so php_check_specific_open_basedir succeeds. tempnam() will then call php_open_temporary_file() which includes an fallback to php_get_temporary_directory(). In most apache setups, php is not able to write to the cwd (cause of safe_mode), so php_open_temporary_file() will fallback. This is not the case when using client, so php -d open_basedir=`pwd` -r 'var_dump(tempnam(false, "temp"));' works. Previous Comments: ------------------------------------------------------------------------ [2006-09-26 16:03:30] [EMAIL PROTECTED] Make sure your phpinfo() display the expected value of open_basedir. Turn on display_errors etc. It doesn't depend on the server API in any way. ------------------------------------------------------------------------ [2006-09-26 15:58:57] manuel at mausz dot at Please try using mod_php. Using the client also don't work for me. Oh and just to be sure: - tried with safe_mode on + off - open_basedir does _not_ include /tmp ;) ------------------------------------------------------------------------ [2006-09-26 15:30:39] [EMAIL PROTECTED] Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip Cannot reproduce: # ./sapi/cli/php -r 'var_dump(tempnam(false, "temp"));' Warning: tempnam(): open_basedir restriction in effect.
