我似乎无法弄清楚这个PHP错误.我已将所有敏感信息替换为“示例”,但我敢打赌,这是我盯着我看的东西,但我没有看到.

这是错误：

Parse error: syntax error, unexpected end of file in /example.php on line 272

<?php 
    session_start();
    // If you haven't entered a number, redirect back to index
    if (!$_SESSION['EXAMPLE'])
        die(header('Location: http://www.example.com/'));

    **//REMOVED THESE ON PURPOSE JUST FYI**
    $servername = "";
    $username = "";
    $password = "";
    $dbname = "";

    // Create Connection
    $con = new mysqli($servername, $username, $password, $dbname);

    // Check Connection
    if ($con->connect_error)
    {
        ("Connection failed: " . $con->connect_error);
    }

    // Search database for number
    $num = $_SESSION['exa'];
    $stmt = $con->prepare("SELECT * FROM numbers WHERE BINARY number = ?");
    $stmt->bind_param("s", $exa);

    $stmt->execute();
    /*$result = $stmt->get_result();
    $row = $result->fetch_assoc();*/

    // Get values out of response
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];
    $example = $result['EXAMPLE'];

    $con->close();
?>

解决方法:

<?php if ($_SESSION['EXAMPLE'] != NULL): ?>
<div class="portfolio-item">
    <span class="glyphicon glyphicon-user"></span><br />
    EXAMPLE
    <br />
</div>
<?php if ($_SESSION['EXAMPLE'] != NULL): ?>

您似乎缺少尾音；每个if()：(替代语法)构造的语句. (这也会产生嵌套这些if构造的不良效果.)

解析器在if()：构造关闭之前到达文件末尾,因此出现“意外的文件末尾”错误.

例如：

<?php if (isset($_SESSION['EXAMPLE'])): ?>
<div class="portfolio-item">
    <span class="glyphicon glyphicon-user"></span><br />
    EXAMPLE
    <br />
</div>
<?php endif; ?>
<?php if (isset($_SESSION['EXAMPLE'])): ?>

我还用isset()更改了不相等比较(！= NULL),这意味着相同的东西(已设置且不为null),并且可能更易于阅读.重要的是,如果未设置变量,则不会触发E_NOTICE.

这也许仅仅是一个例子,但是如果您逐字地进行相同的比较,那么您最好将它们组合成一个if()：构造.

在旁边：

if (!$_SESSION['EXAMPLE'])
    die(header('Location: http://www.example.com/'));

如果未设置$_SESSION [‘EXAMPLE’],这将触发E_NOTICE.您最好检查！isset()或empty(),具体取决于它可能包含的值.例如：

if (empty($_SESSION['EXAMPLE']))
    // Error...

使用empty()更容易阅读,但请首先检查它是否适合您的情况.如果变量的值为假(即“”,“ 0”,0,假,空,未设置),则将其视为“空”.
