}

$data ['liuyan'] = $this->ly->getLy ( $pernum, $currentnum );

其中：

復制代碼代碼如下:

$current_page=is_numeric($this->uri->segment ( 3 ))?intval($this->uri->segment ( 3 )):1;

$currentnum = is_numeric($this->uri->segment ( 3 ))?(intval($this->uri->segment ( 3 ) - 1)) * $pernum;

這兩句判斷了參數(shù)是否為數(shù)字。防止非法字符輸入。
