I have been trying to post a status at scheduled date/time to Facebook using PHP cURL.

I am using the unix timestamp value to the parameter scheduled_publish_time and published=false. In Facebook I can see my post being scheduled at the given time.

but unfortunately nothing gets posted at that time and Facebook still shows the message as "next post scheduled for #time" even after the time has elapsed.

Code:

<?php
  $facebook_page_id='xxx';    
  $facebook_page_access_token="xxx";

  //Facebook page post
  $status='scheduled post'; 
  $fb_page_post="https://graph.facebook.com/{$facebook_page_id}/feeds?message=$status&scheduled_publish_time=1431683900&published=false&access_token=$facebook_page_access_token";

  $ch=curl_init();
  curl_setopt($ch, CURLOPT_URL, $fb_page_post);
  curl_setopt($ch, CURLOPT_POST, true);
  curl_setopt($ch, CURLOPT_REFERER, '');
  curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate');
  curl_setopt($ch, CURLOPT_AUTOREFERER, true);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_TIMEOUT, 10);

  $fb_page_post = json_decode(curl_exec($ch));
  curl_close($ch);

  var_dump($fb_page_post);

when I run this script through terminal and var_dump() the response it gives me an output as :

object(stdClass)#2 (2) {
["id"]=>
string(16) "1414369492218829"
["post_id"]=>
string(33) "1387602394895539_1414369492218829"
}

what is the solution for this ? What necessary changes do I need to make ?

Thank you for any Help

Remove published=false. It means that no feed story should be created, at all.

Using scheduled_publish_time only is what you need to create a scheduled post, that will only appear on the page’s timeline when the specified timestamp is reached.
