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;">
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。
