Question

当我在localhost服务器中运行代码时，它可以正常工作，但是当我们在实时服务器（Godaddy linux共享服务器）中运行相同的代码时，则会出现sql连接失败的错误。数据库很大，在我们的本地服务器中，查询大约需要2分钟才能返回数据，因此在共享的Godaddy服务器中，查询必须花费更多时间。

<?php
$conn = mysqli_connect("localhost","root","","doreme_eshop");

// $mysqli = new mysqli("localhost", "root", "", "doreme_eshop");
// if ($mysqli->connect_errno) {
//     echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
// }

if(isset($_POST['submit'])){
 $style=$_REQUEST['style_no'];
$result = mysqli_query($conn,"CALL style_report('".$style."')") or die("Query Failed: " . mysqli_error($conn));

//var_dump($result->fetch_assoc());

echo "<table border='1'>
<tr>
<th>total_set</th>
<th>style_no</th>
<th>size_id</th>
<th>size_description</th>
<th>Company_name</th>
<th>generate_no</th>
<th>order_Date</th>
<th>product_id</th>
</tr>";

while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['total_set'] . "</td>";
echo "<td>" . $row['style_no'] . "</td>";
echo "<td>" . $row['size_id'] . "</td>";
echo "<td>" . $row['size_description'] . "</td>";
echo "<td>" . $row['Company_name'] . "</td>";
echo "<td>" . $row['generate_no'] . "</td>";
echo "<td>" . $row['order_Date'] . "</td>";
echo "<td>" . $row['product_id'] . "</td>";
echo "</tr>";
}
echo "</table>";
}

您需要设置连接超时，其次您可以将配置文件设置为require_once分开。

尝试检查数据库是否具有mysqli库，...仅打开连接，然后关闭并检查错误

超时错误和连接丢失
