Answer 1

Won't you have to use {$url} instead?

It is also better to encode the $url using urlencode() as well.

Answer 2

In response to the other answer by 動靜能量,

I don't think that should be encoded with urlencode since it is in a string.

Instead, check if you have magicquotes enabled (you can check the status with the command get_magic_quotes_gpc() )

If you have magicquotes enabled, you don't have to screen the input, it is already filtered. If it is not enabled, instead of urlencode, use addslashes. I believe the code would be:

$facebook->api_client->fql_query('SELECT user_id FROM like WHERE post_id="{'.addslashes(url).'}"');
