Facebook图形api与php-共享计数

Question

im trying to get wordpress post facebook share count in foreach, but..

<?php 

$post_url = the_permalink();
$url_changed = urlencode($post_url);

$json = file_get_contents( 'http://graph.facebook.com/?id=' . $url_changed );

ini_set("allow_url_fopen", 1);


$array = json_decode($json, true);
echo $array['share']['share_count']; 

?>      

This gives me only to id="" and error

file_get_contents( http://graph.facebook.com/?id= ): failed to open stream: HTTP request failed! HTTP/1.1 400 Bad Request

But if use

$json = file_get_contents( 'http://graph.facebook.com/?id=http://www.google.com' );

Like that, then it works. Does somebody know workaround or how to get it right?

Answer 1

the_permalink() displays the current URL and not returning the value, use get_permalink() instead..
