  Total Records: <?php echo $total_records ?>

Answer 1

class Test index function最后一句话)遗失。这是正确的

$this->load->view('test_view', array('total_records' => $total_records));

Answer 2

可能是由于脚本包含在视图中，在htaccess文件中设置short_open_tag 0并检查是否解决

＆lt; IfModule mod_php5.c＆gt;

php_value short_open_tag 0

＆lt; / IfModule＆gt;
