Question

I want to have a PHP variable which value is generated by FBML.

I can do that by go back and forth through AJAX.

I wonder that it can be done purely in PHP.

This seems nonsense but what I want to do is like this. Just to show my idea.

$value = echo "<fb:comments-count href=$url></fb:comments-count>";

Is there a way to make this work?

Answer 1

ob_start();
echo "<fb:comments-count href=$url></fb:comments-count>";
$value = ob_get_clean();
ob_end_clean();

But it is still pointless. As long as you can perform echo, you could perform variable assigning also.
