MySQLi 绑定插入与查询实例<?php $conn = new mysqli('localhost','root','','orders'); //连接 $PRepare = "insert into t100 values (?,?,?)";//预设插入sql $bind = $conn->prepare($prepare); $t1 = NULL; $t2 = 'Www'; $t3 = date('Y-m-d H:i:s'); $bind->bind_param('iss',$t1,$t2,$t3); //绑定 //注意iss： //i为int，s为string类型；意思是强制这几个参数的类型 $bind->execute();//执行 $prepare = "select * from t100"; //准备要查询的语句 $bind = $conn->prepare($prepare);//预处理 $t1 = 10; $bind->execute();//执行 $bind->bind_result($id, $name, $date);//将字段列绑定到变量上 $bind->store_result();//获取结果集 while ($bind->fetch()){//遍历 printf("%d == %s == %s<br />",$id,$name,$date);//输出 }
