1. 投票主頁(yè)面：

<?php$arr=$_POST["xx"];include ("../DBDA.class.php");$db=new DBDA();foreach($arr as $v){ $sql = "update diaoyanxuanxiang set numbers = numbers+1 where ids = '{$v}'"; $db->Query($sql,1);//1代表$sql的類(lèi)型}header ("location:TouPiao.php");?>3. 建立訪問(wèn)數(shù)據(jù)庫(kù)的類(lèi),封裝用于引用：
<?php//執(zhí)行一個(gè)sql語(yǔ)句，返回相應(yīng)的結(jié)果class DBDA{ public $host="localhost";//數(shù)據(jù)庫(kù)服務(wù)器地址 public $uid="root";//數(shù)據(jù)庫(kù)用戶名 public $password="";//數(shù)據(jù)庫(kù)密碼 //執(zhí)行SQL語(yǔ)句的方法 //參數(shù)里面：$sql代表要執(zhí)行的sql語(yǔ)句；$type是sql語(yǔ)句的類(lèi)型，0代表查詢，1代表其他(增刪改)；$db代表要操作的數(shù)據(jù)庫(kù) function Query($sql,$type=0,$db="0710_info") { //造連接對(duì)象 $dbconnect=new MySQLi($this->host,$this->uid,$this->password,$db); //判斷連接是否出錯(cuò) !mysqli_connect_error() or die("連接失敗！"); //執(zhí)行sql語(yǔ)句 $result=$dbconnect->query($sql); //判斷SQL語(yǔ)句類(lèi)型 if($type==0) { //如果是查詢語(yǔ)句返回結(jié)果集的二維數(shù)組 return $result->fetch_all(); } else { //如果是其他語(yǔ)句，返回true或false return $result; } } }總結(jié)
以上所述是小編給大家介紹的使用PHP+MySql實(shí)現(xiàn)微信投票功能實(shí)例代碼，希望對(duì)大家有所幫助，如果大家有任何疑問(wèn)請(qǐng)給我留言，小編會(huì)及時(shí)回復(fù)大家的。在此也非常感謝大家對(duì)VeVb武林網(wǎng)網(wǎng)站的支持！
