模板文件放在./application/template/default/目录里 以.html结尾的html文件 编译后的文件在./application/views/目录里以.PHP结尾文件存放.
用法:
把文件放在libraries目录 然后 在你的控制器里$this->load->library ( 'template' ); $this->template->Template ( 'header' ) ，header是存放在./application/template/default目录下的一个html文件,此库来自第三方，并非本人所著，只是用于学习, 标签用法和uchome差不多，也不完全.
例举几个吧： {BASE_URL}images/favicon.ico将被替换成 <?= base_url ();?>images/favicon.ico的结果 如：http://codeigniter.org.cn/images/favicon.ico {echo $hello}将被替换成<?php echo $hello; ?>
