Php七更新搞砸了我的程序

Question

最近，随着php 7的更新，他们删除了所有的mysql命令。但是，我实习的一个程序是在其中一个页面中使用这些命令。然而，当我把它改成mysqli它不再像它应该的那样工作。有人可能会帮忙吗？

$connection = mysqli_connect($db_host, $db_username, $db_password) or die("Error " . mysqli_error());

//select MySQLi dabatase table
$db = mysqli_select_db($connection, "table") or die("Error " . mysqli_error());


$result = mysqli_query($connection, "SELECT * FROM gebiedsmanagers WHERE Datum >= NOW()");

Warning: mysqli_select_db() expects parameter 1 to be mysqli, string given:
mysqli_select_db("prodyne", $con);

要

mysqli_select_db($con, "prodyne")

试一试！

    <?php


    //MySQLi information

    $db_host     = "localhost";
    $db_username = "username";
    $db_password = "password";

    //connect to mysqli database (Host/Username/Password)
    $connection = mysqli_connect($db_host, $db_username, $db_password) or die("Error " . mysqli_error());

    //select MySQLi dabatase table
    $db = mysqli_select_db($connection, "table") or die("Error " . mysqli_error());

    //fetch information from your database
    $result = mysqli_query($connection, "SELECT * FROM gebiedsmanagers WHERE Datum >= NOW()");
      while($row = mysqli_fetch_array($result))

               {   
                  $counter ++;

?>
<tr><td><?php echo date('d-m-Y', strtotime($row['Datum']));?></td><td>
<?php echo $row['Voor1500']; ?></td><td><?php echo $row['Na1500']; ?>
</td></tr>
<?php

             if($counter >= 120) {             
                break;     
          }

我希望这对你有帮助。
