本文實例講述了php實現的用戶查詢類。分享給大家供大家參考。具體實現方法如下：
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 <?php class user { var $usertable; function get_oneuser($field,$value) { $field_array=array("id","name"); //查詢方式 if(in_array($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 "查詢方式不對"; } 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; } } ?>
希望本文所述對大家的php程序設計有所幫助。
