funcstions.php böyle başlıyor 0.satırda hata görüyor ama <?php olarak başlıyor hata nerede anlamadım

<?php
/*------------------------------------------------------------

function likeThis($post_id,$action = 'get') {

if(!is_numeric($post_id)) {
error_log("Error: Value submitted for post_id was not numeric");
return;
} //if

switch($action) {

case 'get':
$data = get_post_meta($post_id, '_likes');

if(!is_numeric($data[0])) {
$data[0] = 0;
add_post_meta($post_id, '_likes', '0', true);
} //if

return $data[0];
break;


case 'update':
if(isset($_COOKIE["like_" . $post_id])) {
return;
} //if

$currentValue = get_post_meta($post_id, '_likes');

if(!is_numeric($currentValue[0])) {
$currentValue[0] = 0;
add_post_meta($post_id, '_likes', '1', true);
} //if

$currentValue[0]++;

setcookie("like_" . $post_id, $post_id,time()*20);
break;

} //switch

function printLikes($post_id) {
$likes = likeThis($post_id);
