Re: is_executable() ???

is_executable() does not check whether a file's contents will do something useful (or dangerous, depending on one's viewpoint) when you execute the file. It just checks if the file has been set as "executable" with http://php.net/chmod ANY file with ANY extension, or NO extension at all, can be an executable on Un*x systems. Your uploaded files should be chmod-ed to NOT be executable, in addition to trying to catch any invalid data contents.
