PHP mysqli stmt绑定结果未获取值
有人能告诉我这个代码有什么问题吗?几个小时以来,我一直试图从数据库中获取值,结果总是空的。。除了用户名和密码PHP mysqli stmt绑定结果未获取值,php,mysql,Php,Mysql,有人能告诉我这个代码有什么问题吗?几个小时以来,我一直试图从数据库中获取值,结果总是空的。。除了用户名和密码 <?php $con = mysqli_connect("aaaaa", "bbbbb", "cccccc", "ddddd"); $email = $_POST["email"]; $password = $_POST["password"]; $statement = mysqli_prepare($con, "SELECT * FROM table WHERE email

好的,我已经用下面的代码解决了我的问题。我不知道以前的代码有什么问题。如果有人碰巧知道这个问题的解决办法,请在评论中回答,我很好奇。注:此代码仅用于测试建议
<?php
$con = mysqli_connect("aaa", "bbb", "ccc", "ddd");
$email = $_POST["email"];
$password = $_POST["password"];
$sql = "SELECT * FROM table";
$result = mysqli_query($con, $sql);
$response = array();
$response["success"] = false;
while($row = mysqli_fetch_assoc($result)){
if($row["email"]==$email && $row["password"] == $password){
$response["success"] = true;
$response["full_name"] = $row["full_name"];
$response["email"] = $row["email"];
$response["password"] = $row["password"];
$response["distance"] = $row["distance"];
$response["average_rating"] = $row["average_rating"];
$response["home_address"] = $row["home_address"];
$response["work_address"] = $row["work_address"];
break;

我建议在while(mysqli_stmt_fetch($statement){echo…}
中对整个内容进行一次echo(只是为了看看发生了什么)。我不确定,但如果我用$response[“full_name”]=$full_name;
更改$response[“full_name”]=“some text”
,我在json响应中获得some text值……这意味着当我将$response
值传递给$response[“full_name”]时,该值为空
,对吗?我不知道如何在while中进行回音,如果我尝试,我会在json响应中得到成功:false
。尝试查询特定字段而不是*@RST,我已经尝试过了,没有任何变化。我建议回音while(mysqli_stmt_fetch($statement){echo…}
一次(只是想看看发生了什么)。我不确定,但如果我用$response[“full\u name”]=$full\u name;
更改$response[“full\u name”]=”一些文本,我认为您正在覆盖$response[]中的值“
,我在json响应中获得了一些文本值……这意味着当我将$response
值传递给$response[“全名”]时,$response
值为空”
,对吗?我不知道在这段时间内如何回音,如果我尝试回音,我会在json响应中得到success:false
。尝试查询特定字段而不是*@RST,我已经尝试过了,没有任何更改。。
