what is the equivilent of facebook api me?

I am trying to write a script that will post to my facebook page and I assume all I have to do is modify my code for posting to a users stream.

$attachment = array
(
  ...
);
$result = $facebook->api($user.'/feed/','post',$attachment开发者_Python百科);

What do I put instead of the user's id? I am not sure if it is simply my page's id. Any ideas?

Assuming that my facebook page means my feed you simply do

$user = 'me';

1. POST ON PAGE'S WALL AS USER:
Publishing on a Page's wall as user is straight forward, you could use something like:

<?php
// path to sdk
require './src/facebook.php';

$facebook = new Facebook(array(
  'appId'  => 'APP_ID',
  'secret' => 'APP_SECRET',
));

$user = $facebook->getUser();
try {
    $post_id = $facebook->api('/TARGET_PAGE_ID/feed', 'POST', array('message'=>"I am a user!"));
    var_dump($post_id);
} catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
}
if ($user) {
  $logoutUrl = $facebook->getLogoutUrl();
} else {
  $loginUrl = $facebook->getLoginUrl(array('scope'=>'publish_stream'));
}
// rest of code here

Note:

• The owner of the post will be the current connected user.
• the above depends on the page's Posting Ability settings.
• you need the publish_stream permission

2. POST ON PAGE'S WALL AS PAGE:
Now to post as a Page you could use something like:

<?php
// This code is just a snippet of the example.php script
// from the PHP-SDK <http://github.com/facebook/php-sdk/blob/master/examples/example.php>
require '../src/facebook.php';

// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
  'appId'  => 'app_id',
  'secret' => 'app_secret',
));

// Get User ID
$user = $facebook->getUser();

if ($user) {
  try {
    $page_id = 'TARGET_PAGE_ID';
    $page_info = $facebook->api("/$page_id?fields=access_token");
    if( !empty($page_info['access_token']) ) {
        $args = array(
            'access_token'  => $page_info['access_token'],
            'message'       => "I'm a Page!"
        );
        $post_id = $facebook->api("/$page_id/feed","post",$args);
    }
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }
}

// Login or logout url will be needed depending on current user state.
if ($user) {
  $logoutUrl = $facebook->getLogoutUrl();
} else {
  $loginUrl = $facebook->getLoginUrl(array('scope'=>'manage_pages,publish_stream'));
}
// rest of code
?>

Notes:

• You need the manage_pages and publish_stream permissions
• Once you obtain the page's access_token you can start posting on its behalf
• More about this is explained in depth in my tutorial.
