Looks perfect.. lstat() and filetype() both work fine on the broken
symlink.. as does is_link(). I'd call it fixed. ;)
file_exists() still 'fails' on a broken symlink, but perhaps it should.
That could get a little on the philosophical side.
Thanks alot for the quick fix!

Just for the record.. here's the code.. and then its output.
--code
function link_func_test ($file)
{
if ( is_link ($file)) { print ("is_link() passed\n"); }
else { print ("is_link() failed\n"); }
if (($link_target = readlink ($file))) {
print ("readlink() passed: $link_target\n");
}
else { print ("readlink() failed\n"); }
if (($temp_filetype = filetype ($file))) {
print ("filetype() passed: $temp_filetype\n");
}
else { print ("filetype() failed\n"); }
if (($temp_lstat = lstat ($file))) {
print ("lstat() passed:\n\n"); print_r ($temp_lstat);
}
else { print ("lstat() failed\n"); }
if (file_exists ($file)) { print ("file_exists() passed:\n"); }
else { print ("file_exists() failed\n"); }
}
$file = '/tmp/test-link-func';
@ unlink ($file);
if (symlink ('/bin/false', $file)) {
link_func_test ($file);
} else { print ("Good symlink failed\n"); }
@ unlink ($file);
if (symlink ('/this/file/does/not/exist', $file)) {
link_func_test ($file);
} else { print ("Bad symlink failed\n"); }
--end
