我有在在該視圖正在加載的性能指標的控制器語法發行次數紀錄。這是說，我有嚴重：解析錯誤 消息：語法錯誤，意外「;」我無法弄清楚是什麼問題，我試圖獲得數據庫中所有記錄的數量。任何幫助，將不勝感激。 控制器/ test.php的有問題與笨

視圖
Total Records: <?php echo $total_records ?>
我認爲這有效，但我現在有另一個問題消息：未定義的變量：total_records – Donny
我沒有添加$ this-> load-> model（'test_model'）;在行上面$ total_records = $ this-> test_model-> count_all_records（）; – Donny
