其处理页面为：
<?php require_once "DBDA.class.php"; $db = new DBDA(); $sql = "select * from minzu"; $arr = $db->query($sql); //将数据转化成字符串 $str = ""; foreach($arr as $v){ $str = $str.implode("^",$v)."|"; } $str = substr($str,0,strlen($str)-1); echo $str;
或可在DBDA中扩展一个方法，使其直接返回一个字符串：
//返回字符串的方法 public function strquery($sql,$type=0){ $db = new mysqli($this->host,$this->uid,$this->pwd,$this->dbname); $result = $db->query($sql); if($type){ return $result; }else{ $arr = $result->fetch_all(); $str = ""; foreach($arr as $v){ $str = $str.implode("^",$v)."|"; } $str = substr($str,0,strlen($str)-1); return $str; } }
这样处理页面只需直接调用即可：
<?php require_once "DBDA.class.php"; $db = new DBDA(); $sql = "select * from minzu"; echo $db->strquery($sql);
