这篇文章主要介绍了php实现的用户查询类,实例分析了php针对用户查询与判断的相关技巧,需要的朋友可以参考下

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:

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。
