eio_symlink — Create a symbolic link
Description
resource eio_symlink ( string $path , string $new_path [, int $pri = EIO_PRI_DEFAULT [, callable $callback = NULL [, mixed $data = NULL ]]] )
eio_symlink() creates a symbolic link new_path
to path
.
Parameters
path
Source path
new_path
Target path
pri
The request priority: EIO_PRI_DEFAULT
, EIO_PRI_MIN
, EIO_PRI_MAX
, or NULL
. If NULL
passed, pri
internally is set to EIO_PRI_DEFAULT
.
callback
callback
function is called when the request is done. It should match the following prototype:
void?callback(mixed?$data,?int?$result[,?resource?$req]);
data
is custom data passed to the request.
result
request-specific result value; basically, the value returned by corresponding system call.
req
is optional request resource which can be used with functions like eio_get_last_error()
`data`
Arbitrary variable passed to callback
.
Return Values
eio_symlink() returns request resource on success or FALSE
on error.
Examples
Example #1 eio_symlink() example
<?php
$filename?=?dirname(__FILE__)."/symlink.dat";
touch($filename);
$link?=?dirname(__FILE__)."/symlink.link";
function?my_symlink_cb($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($filename);
}
eio_symlink($filename,?$link,?EIO_PRI_DEFAULT,?"my_symlink_cb",?$link);
eio_event_loop();
?>
The above example will output something similar to:
bool(true)
string(16) "/tmp/symlink.dat"
