谢谢你提前回复

解析错误：语法错误，第45行的insert.php中出现意外的T_ELSE

请检查我的insert.php代码是否有错误。。试图联系，但没有成功。。它在浏览器中转到insert.php，但它是一个空白页

以下是insert.php：

<?php
$email = $_POST['email'];

if (!empty($email)){
    $host = "localhost";
    $dbUsername = "root";
    $dbPassword = "password";
    $dbname = "newsletters_soon_db";
} else {
    echo "Email Address is required";
    die();
}   
// Create Connection
$conn = new mysqli($host, $dbUsername, $dbPassword, $dbname);

if (mysqli_connect_error()) {
    die('Connection Error('.mysqli_connect_error().')'.mysqli_connect_error());
}else{
    $SELECT = "SELECT email from email_newsletters Where email = ? Limit 1";
    $INSERT = "INSERT Into email_newsletters (email) values(?)";
    //Prepare statement
    $stmt = $conn->prepare($SELECT);
    $stmt->bind_param("s", $email);
    $stmt->execute();
    $stmt->bind_result($email);
    $stmt->store_result();
    $rnum = $stmt->num_row;

    if ($rnum==0){
        $stmt->close();

        $stmt = $conn->prepare($INSERT);
        $stmt->bind_param("s",$email);
        $stmt->execute();
        echo "New record inserted successfully";
    } else {
        echo "You are already registered using this email, please type an other email address to receive updates";
    }
    $stmt->close();
    $conn->close();
}else {
    echo "Please insert insert";
    die();
}

我制作了一个名为it Newslettes_soon_db的数据库，并在其中制作了一个名为it email_Newslettes的表格，还有一个名为it email的专栏，长度为40，名为Varchar

提前感谢您的帮助

您的if（mysqli_connect_error（））{else语句是if…else…else

它必须是if…else if…else或删除最后一条else语句

这是您应该在错误日志中看到的错误

解析错误：语法错误，第45行insert.php中意外的T_ELSE

Add

ini_集（'display_errors'，1）；ini_集（'log_errors'，1）；错误报告（E_ALL）；mysqli_报告（mysqli_report_error | mysqli_report_）；

到脚本顶部。这将强制任何

mysqli\uu

错误生成一个在浏览器上可以看到的异常，其他错误也将在浏览器上可见。更改

$stmt->num\u行；

到

$stmt->num\u行；

请养成查看PHP错误日志的习惯，我尝试使用您的方法“愚蠢"为了检查错误，但它没有打印任何东西，页面是空白的，不知道为什么。我在这里搜索网站，我想出了这个方法：在终端中..键入这个：php-l phpfilename.php，错误会立即出现。你有没有在php错误日志中查找线索？谢谢你的回复..是的，我更正并删除了最后一个，它可以工作..我我想知道如何用if..elseif..else来更正代码在我的情况下..只是想从你那里了解一些知识：）谢谢，我不清楚最后一个else语句应该由什么触发。下面是一个简单的例子if（$rnum==0）{//do something}else if（$rnum==1）{//do something}else{echo“返回的记录太多”}我认为不可能在代码中添加最后一个else..我添加了最后一条语句，用于验证文本字段是否为空..但我确实删除了它及其工作。
