Wamp服务器显示任何实际的语法错误宽度错误

Question

我创建了一个简单的php脚本，用于使用wamp将数据上传到MySQL服务器。 我的脚本 -

<?php 
    $server = "127.22.9.0"; 
    $user = "root"; 
    $password = ""; 
    $db = "complaints"; 

    $conn = new mysqli($server, $user, $password, $db); 

    if ($conn->connect_error) { // This is that line 9 
     die("Connection failed: " . $conn->connect_error); 
    } 

    echo "Connected successfully"; 

    $sql = "INSERT INTO complaints (email, title, details) VALUES ('".$_POST['email']."', '".$_POST['title']."', '".$_POST['dtls']."')"; 

    if ($conn->query($sql) === TRUE) { 
     echo "New record created successfully"; 
    } else { 
     echo "Error: " . $sql . "<br>" . $conn->error; 
    } 
?> 

当我执行此WAMP的服务器上，它显示了一个错误

Parse error: syntax error, unexpected '{' in C:\wamp64\www\index.php on line 9 

我已经彻底搜查了错误，但一无所获。

任何人都可以帮助我吗？

编辑：我解决我的问题，但在一个不寻常的方式 -

我重新输入我的代码，并去掉了一些不必要的空间和改变，如果语句的结构。现在，我的代码工作 -

$server = "127.22.9.0"; 
$user = "root"; 
$password = ""; 
$db = "complaints"; 

$conn = new mysqli($server, $user, $password, $db); 

nl2br($_POST['dtls']); 

if($conn->connect_error) 
{ 
    die("Error: ".$conn->connect_error); 
} 

$sql = "INSERT INTO complaints (email, title, details) VALUES ('".$_POST['email']."', '".$_POST['title']."', '".$_POST['dtls']."')"; 

if($conn->query($sql)) 
{ 
    echo "<h1>Success!! Your complaint has been successfully registered!!</h1>"; 
} 
else 
{ 
    echo "Error: " . $sql . "<br>" . $conn->error; 
} 

这些更改是相当不必要的，但它的工作原理。

Answer 1

$conn = new mysqli($server, $user, $password, $db); 
if (!$conn) { 
die("Connection failed: " . mysqli_connect_error()); 
} 
echo "Connected successfully";
