本文实例讲述了php实现的用户查询类。分享给大家供大家参考。具体实现方法如下:
- <?php
- class user
- {
- var $usertable;
- function get_oneuser($field,$value)
- {
- $field_array=array("id","name"); //查询方式
- if(in_array($field,$field_array))
- {
- $sql="SELECT * FROM `$this->usertable` WHERE $field='$value'";
- $db=new database;
- $res=$db->execute($sql);
- $obj_user=mysql_fetch_object($res);
- return $obj_user;
- }
- else echo "查询方式不对";
- }
- function get_moreusers()
- {
- global $db;
- $argnums=func_num_args();
- $argarr=func_get_args();
- switch($argnums)
- {
- case 0:
- $sql="SELECT * FROM `$this->usertable`";
- break;
- case 2:
- $sql="SELECT * FROM `$this->usertable` WHERE $argarr[0]='$argarr[1]'";
- break;
- case 4:
- $sql="SELECT * FROM `$this->usertable` WHERE $argarr[0]='$argarr[1]' AND $argarr[2]='$argarr[3]'";
- break;
- }
- //$db=new database;
- $res=$this->execute($sql);
- $obj_arr=array();
- while($obj=mysql_fetch_object($res))
- {
- $obj_arr[]=$obj;
- }
- return $obj_arr;
- }
- }
- ?>
希望本文所述对大家的php程序设计有所帮助。
