Question

我正在遵循教程(here)，并且它已经过时了php，而我的Google搜索没有帮助我，所以我想知道如何使它正常工作？

它显示有500页没有工作（当前无法处理此请求。）

编辑。我忘记添加代码了。

<?php
header('Access-Control-Allow-Origin: *');




$host="localhost"; // Host name 
$username="username"; // Mysql username 
$password="password"; // Mysql password 
$db_name="name"; // Database name 
$tbl_name="scores"; // Table name

// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

// Retrieve data from database 
$sql="SELECT * FROM scores ORDER BY score DESC LIMIT 10";
$result=mysql_query($sql);

// Start looping rows in mysql database.
while($rows=mysql_fetch_array($result)){
echo $rows['name'] . "|" . $rows['score'] . "|";

// close while loop 
}

// close MySQL connection 
mysql_close();
?>

我还如何解决此代码？

 $dblink = mysql_connect($host,$dbu,$dbp);
$seldb = mysql_select_db($db);

if(isset($_GET['name']) && isset($_GET['score'])){

     //Lightly sanitize the GET's to prevent SQL injections and possible XSS attacks
     $name = strip_tags(mysql_real_escape_string($_GET['name']));
     $score = strip_tags(mysql_real_escape_string($_GET['score']));
     $sql = mysql_query("INSERT INTO `$db`.`scores` (`id`,`name`,`score`) VALUES ('','$name','$score');");

     if($sql){

          //The query returned true - now do whatever you like here.
          echo 'Your score was saved. Congrats!';

     }else{

          //The query returned false - you might want to put some sort of error reporting here. Even logging the error to a text file is fine.
          echo 'There was a problem saving your score. Please try again later.';

     }

}else{
     echo 'Your name or score wasnt passed in the request. Make sure you add ?name=NAME_HERE&score=1337 to the tags.';
}

mysql_close($dblink);//Close off the MySQL connection to save resources.

以下是使用mysqli的示例

public class A
{
    private readonly int i;

    public A()
    {
        Action setI = () => i = 10;

        setI();
    }
}
