resource eio_link ( string $path, string $new_path [, int $pri = EIO_PRI_DEFAULT [, callable $callback = NULL [, mixed $data = NULL ]]] )
eio_link() creates a hardlink new_path for a file specified by path.
Parameters:
path
Source file path.
new_path
Target file path.
pri
The request priority: EIO_PRI_DEFAULT, EIO_PRI_MIN, EIO_PRI_MAX, or NULL. If NULL passed, pri internally is set to EIO_PRI_DEFAULT.
callback
callback function is called when the request is done. It should match the following prototype:
void callback(mixed $data, int $result[, resource $req]);
data
Arbitrary variable passed to callback.
Returns:

eio_link() example
<?php
$filename = dirname(__FILE__)."/symlink.dat";
touch($filename);
$link = dirname(__FILE__)."/symlink.link";
$hardlink = dirname(__FILE__)."/hardlink.link";
function my_hardlink_cb($data, $result) {
global $link, $filename;
var_dump(file_exists($data) && !is_link($data));
@unlink($data);
eio_symlink($filename, $link, EIO_PRI_DEFAULT, "my_symlink_cb", $link);
}
function my_symlink_cb($data, $result) {
global $link, $filename;
var_dump(file_exists($data) && is_link($data));
if (!eio_readlink($data, EIO_PRI_DEFAULT, "my_readlink_cb", NULL)) {
@unlink($link);
@unlink($filename);
}
}
function my_readlink_cb($data, $result) {
global $filename, $link;
var_dump($result);
@unlink($link);
@unlink($filename);
}
eio_link($filename, $hardlink, EIO_PRI_DEFAULT, "my_hardlink_cb", $hardlink);
eio_event_loop();
?>
The above example will output something similar to:
bool(true) bool(true) string(%d) "%ssymlink.dat"
