php中操作memcached缓存进行增删改查数据的实现代码,phpmemcached
核心代码:
<?php //创建一个memcache对象实例 $memcache = new Memcache; if(!$memcache->connect("127.0.0.1",11211)){ die('连接失败'); } if($memcache->set('key1',"xian",MEMCACHE_COMPRESSED,60)){ echo 'sucess!'; }//存值,其中xian字符串,也可以为数组,对象,但不能为资源 $val = $memcache->get('key1');//查询获取值 echo $val; $memcache->replace('key1','beijing',MEMCACHE_COMPRESSED,60);//修改 $memcache->delete('key1');//删除 ?>
嚯,这不就是个小型的后台操作么。
给个思路吧:做个表格,用个foreach循环一次性打印出表的信息,并呈现在table表格里,在表格的后两个td里分别写上编辑、删除,至于增加则要单开页面了,编辑时把id给传过去,一次取出该id的所有值并付给要相关的value值,删除更简单,根据传过去的id删除表里那行数据
至于上传图片,则要封装给图片处理的库了,只需把图片名传过去,通过$_FILES全局变量进行相关的操作,如判断上传文件的后缀、大小以及上传失败后呈现给客户的信息等。
看着好乱啊 !
