(PHP 3, PHP 4 >= 4.0.0)

is_executable -- Tells whether the filename is executable

Description

bool is_executable (string filename)

Returns TRUE if the filename exists and is executable.

The results of this function are cached. See clearstatcache() for more details.

This function will not work on remote files; the file to be examined must be accessible via the server's filesystem.

See also is_file() and is_link().

[Editor's Note: This is the expected behavior (at least on most Unix-like systems). If a directory is not executable, then you cannot get details on the files in the directory - this includes the permissions. --zak@php.net] This does not work on directories! look at this example: if(is_file("foo/bar")) print "found it"; if "bar" exists, but directory "foo" is not executable, you will NOT get "found it" as result.
