<?php$mysql_server_name=‘localhost‘; //改成自己的mysql数据库服务器$mysql_username="root"; //改成自己的mysql数据库用户名$mysql_password="qmtg"; //改成自己的mysql数据库密码$mysql_database="testmydatabase"; //改成自己的mysql数据库名$conn=new mysqli($mysql_server_name,$mysql_username,$mysql_password); //连接数据库if($conn==false){ ???echo "数据连接失败！";}else{ ???echo "数据连接成功！";} $conn->query("set names ‘utf8‘"); //数据库输出编码 应该与你的数据库编码保持一致.南昌网站建设公司百恒网络PHP工程师建议用UTF-8 国际标准编码.$conn -> select_db($mysql_database); //打开数据库$sql ="select * from testtale "; //SQL语句$result = $conn->query($sql); //查询成功$data=array();echo "start".PHP_EOL; ???while ($tmp=$result->fetch_assoc()) ????{ ???????$data[]=$tmp; ???????echo ?"name:".$tmp[‘name‘] . PHP_EOL ; ?????????} ???//echo json_encode($data);//var_dump($data);print_r($data);echo "end".PHP_EOL;class person{ ???public $name; ???public $age; ???public $height; ???function __construct($name,$age,$height) ???{ ???????$this->name = $name; ???????$this->age = $age; ???????$this->height = $height; ???????} ??}$obj = new person("zhangsan",20,100);$foo_json = json_encode($obj);echo $foo_json;$d = $_GET[‘test‘];echo $d;?>
2.这句就是接收
