Need help with sending js

Okay, so I need to enqueue a script that is dependent on jQuery.

However the script needs to json_encode(wp_get_current_user()) so it can’t run until after WP is loaded.

I put an init action in functions in the theme file which does the wp_enqueue_script, which I think should do the trick, however I get Fatal error call to undefined function wp_get_current_user() from the script.

functions.php

add_action('init', 'send_cur_user_script');
function send_cur_user_script() {
	wp_enqueue_script('curuser', get_template_directory_uri() . '/js/curuser.php', array('jquery') );
}

js/curuser.php

<?php
	$current_user = json_encode(wp_get_current_user());
?>
// JavaScript Document

var curuser = <?php echo $current_user;?>;
jQuery(function() {
	jQuery(curuser.market.join(", ")).removeClass("model-tab-gone");
});

the var curuser assignment is not working and throwing an error?

Any help on how to do this?
