index.php
echo '<a href="'<?php echo SITEURL; ?>'IndonusaCMS/event_article.php?id='.$data['ID'].'">'.$data['title'].'</a>';
wds.php
<?php
define('SITEURL', 'http://www.indonusa.net.id/');
?>
When I try to run index.php this error appears:
Parse error: syntax error, unexpected '?' in E:\xampp\htdocs\IndonusaCMS\index.php on line 106
How to fix it?
