本文实例讲述了thinkphp实现二级循环读取的方法。分享给大家供大家参考。具体实现方法如下：
复制代码 代码如下:
$category = d('category')->where('category_pid=0')->findall();
//dump($category);
if(!empty($category)){ //判断一级是否为空
foreach($category as $key=>$value){ //循环读取
$pid = $value['category_id'];//字段赋值
$category[$key]['child'] = d('category')->where(category_pid =$pid)->select();
//echo d('category')->getlastsql(); //打印sql语句的写法
}
}
//dump($category);
$this->assign('category',$category);//映射值
希望本文所述对大家的thinkphp框架程序设计有所帮助。
