I noticed that, differently from Unix ln command, the second parameter can´t be a directory name, i.e., if you want to create a link with the same filename of the target file (obviously on different directories), you must specify the filename on the link parameter.

Example:
Unix ln command:
ln /dir1/file /dir2/   // ok, creates /dir2/file link

PHP link function:
link ("/dir1/file", "/dir2/");   // wrong, gives a "File exists" warning
link ("/dir1/file", "/dir2/file");   // ok, creates /dir2/file link

For a backup utility I needed link-like functionality on a windows system. As it isn't availible on windows, i tried to do it myself with the help of some tools. All you need is junction.exe from sysinternals in your %PATH%.

<?php
if(!function_exists('link')){ // Assume a windows system
   
function link($target$link){
        if(
is_dir($target)){
           
// junctions link to directories in windows
           
exec("junction $link $target"$lines$val);
            return 
== $val;
        }elseif(
is_file($target)){
           
// Hardlinks link to files in windows
           
exec("fsutil hardlink create $link $target"$lines$val);
            return 
== $val;
        }
       
        return 
false;
    }
}
?>

to clarify:

in unix/linux:
hardlinks (by this function) cannot go across different filesystems.
softlinks can point anywhere.

in linux, hardlinking to directory is not permited.
