After editing a user note in online manual, I was/am redirected to admin-notes.php and the following is one of the errors that exists :


Warning: stat failed for function.function.print.php.php (errno=2 - No such file or directory) in /local/Web/sites/phpweb/include/layout.inc on line 346


Of course, despite these Warnings, the edit succeeds.  I didn't realize is_file creates such Warnings, maybe this should be a bug report for is_file?  Or, turn down your error_reporting level :-)

error_reporting(E_ALL);

if (is_file('idontexist.php'))     // creates warning
if (file_exists('idontexist.php')) // no warning
