原生php实现登录接口（+测试数据）(不加任何封装)

测试数据在贵哥的编程之路资源里面

<?php
$link=mysqli_connect('localhost','root','','a');
//然后是指定php链接数据库的字符集
mysqli_set_charset($link,'utf8');
if(empty($_POST['phone']))
{
    return "请输入手机号";
}
if(empty($_POST['pwd']))
{
    return "请输入密码";
}
$sql="select * from php_user where status=1 and phone=".$_POST['phone']."limit 0,1";
$result=mysqli_query($link,$sql);//运行sql
if(mysqli_num_rows($result) > 0){
    while($row = mysqli_fetch_assoc($result)) {
    $data[] = $row;}$json = json_encode(array("resultCode"=>200,"message"=>"查询成功！","data"=>$data),JSON_UNESCAPED_UNICODE);//转换成字符串JSONecho($json);
}else{
    $json = json_encode(array("resultCode"=>200,"message"=>"暂无数据","data"=>''),JSON_UNESCAPED_UNICODE);//转换成字符串JSONecho($json);
}
