#31570 [NEW]: PHP unable to resolve relative paths in __destruct() upon unloading page

From: twadzilla at gmail dot com Operating system: Redhat 9 PHP version: 5CVS-2005-01-16 (dev) PHP Bug Type: Zend Engine 2 problem Bug description: PHP unable to resolve relative paths in __destruct() upon unloading page Description: ------------ PHP generates a warning inside a class destructor when you try to read a file, because apparently it cannot resolve relative paths by the time when the destructor is called for referenced objects. When the open_basedir config is commented out, only the "include" directive resolves the relative path; the other file-reading methods fail. When open_basedir is in effect, it causes all the methods to fail, including the "include" directive. The following issue is demonstrated at: http://test.kneetoe.com/foo.php http://test.kneetoe.com/foo.php.txt (alternatively with more checks): http://test.kneetoe.com/foo2.php http://test.kneetoe.com/foo2.php.txt I recommend that class destructors get executed before the ability to resolve relative paths gets unloaded. http://test.kneetoe.com/phpinfo.php Reproduce code: --------------- [httpd.conf]: php_admin_value open_basedir /home/test/www [/home/test/www/bar.html]: Bar! [/home/test/www/foo.php]: class Foo { function __destruct() { $relative = 'bar.html'; $absolute = "/home/test/www/$abs"; echo "Absolute 'include': "; include $absolute; echo "Relative 'include': "; include $relative; echo "Absolute 'readfile': "; readfile($absolute); echo "Relative 'readfile': "; readfile($relative); } } print "<h2>Non-referenced (immediate destruction):</h2>"; new Foo; print "<h2>Referenced (delayed destruction):</h2>"; $a = new Foo; Expected result: ---------------- Non-referenced (immediate destruction): Absolute 'include': Bar! Relative 'include': Bar! Absolute 'readfile': Bar! Relative 'readfile': Bar! Referenced (delayed destruction): Absolute 'include': Bar! Relative 'include': Bar! Absolute 'readfile': Bar!
