Question

我使用的是wampserver php 5.6.16版，我试图从表单提交中收集数据：

//First create database
CREATE DATABASE 'college';
Then create table
CREATE TABLE 'students' (
'student_id' int(11) NOT NULL AUTO_INCREMENT,
'student_name' varchar(255) NOT NULL,
'student_email' varchar(255) NOT NULL,
'student_city' varchar(255) NOT NULL,
PRIMARY KEY ('student_id') )

之后我创建页面代码：

<html>
<head>
<title>insert data in database using mysqli</title>
</head>
<body>

<div id="main">
<h1>Insert data into database using mysqli</h1>
<div id="login">
    <h2>Student's Form</h2>
    <hr/>
    <form action="kiri.php" method="POST">
        <label>Student Name :</label>
        <input type="text" name="stu_name" id="name" required="required" placeholder="Please Enter Name"/><br /><br />
        <label>Student Email :</label>
        <input type="email" name="stu_email" id="email" required="required" placeholder="john123@gmail.com"/><br/><br />
        <label>Student City :</label>
        <input type="text" name="stu_city" id="city" required="required" placeholder="Please Enter Your City"/><br/><br />
        <input type="submit" value=" Submit " name="submit"/><br />
    </form>
</div>


</div>
<?php
if(isset($_POST["submit"])){
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "college";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = "INSERT INTO students (student_name, student_email, student_city)
VALUES ('".$_POST["stu_name"]."','".$_POST["stu_email"]."','".$_POST["stu_city"]."')";

if ($conn->query($sql) === TRUE) {
    echo "<script type= 'text/javascript'>alert('New record created successfully');</script>";
} else {
    echo "<script type= 'text/javascript'>alert('Error: " . $sql . "<br>" . $conn->error."');</script>";
}

$conn->close();
}
?>
</body>
</html>

但是我收到了这个错误：

不推荐使用：自动填充$ HTTP_RAW_POST_DATA已弃用，将在以后的版本中删除。为了避免这种警告，请设置“always_populate_raw_post_data＆＃39;到＆＃39; -1＆＃39;在php.ini中使用php：//输入流代替。在第0行的未知中

警告：无法修改标题信息 - 已在第0行的“未知”中发送的标题

提交php错误的SQLI表单提交
