is_executable

(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.

`to test whether the directory /home/david is executable (regardless of whether it is readable or writeable), issue the command: $my_isWriteable = @file_exists("/home/david/.") the @ gets rid of the warning when this command fails when the directory is not executable.`
