Previous Comments: ------------------------------------------------------------------------ [2004-11-27 14:20:40] sat at lomejordeinternet dot net http://www.php.net/manual/en/features.safe-mode.php#ini.open-basedir "Limit the files that can be opened by PHP to the specified directory-tree, including the file itself. This directive is NOT affected by whether Safe Mode is turned On or Off. When a script tries to open a file with, for example, fopen() or gzopen(), the location of the file is checked. When the file is outside the specified directory-tree, PHP will refuse to open it. All symbolic links are resolved, so it's not possible to avoid this restriction with a symlink.
