Define PHP var using a global var

Question

I am trying to get a php snippet working within a template with PHP enabled(output).

$uid does contain the {member_id} as expected but the php has not returned the correct result.

Update I think this is parse order issue.

What is wrong here?

<?php
  $uid = "{member_id}";
?>

This most likely is parse order, however as your trying to get a global into a php variable you can forget about tag parsing completely. Try this :

$uid = ee()->session->userdata('member_id');

Member ID is in the Session class (if logged in), test the group for if_logged_in or not.

FYI, for other global vars, you can do things like this :

//Global Variables (Site Label)
$var = ee()->config->_global_vars['site_label'];

//Global config settings (Base URL)
$var = ee()->config->config['base_url'];

//User variables (alternate method)
$var = ee()->session->userdata['group_id'];
