php - 奇怪＆＃34;意外的文件结尾＆＃34;错误

Question

最近我完成了一个小型的php项目，一切都在我的2台mac上完美运行，使用xampp显示我的工作，但是当使用xampp在Windows机器上测试时，我一直收到这个错误：

  

解析错误：语法错误，第161行的C：\ xampp \ htdocs \ IT2B \ cart.php中的文件意外结束

我已经知道这个错误意味着我的代码中有一个未封闭的括号，但经过几个小时的搜索后，我仍然无法解决此错误消息。我已计算每个左括号，并且打开的数字与关闭时相同，表示所有括号都已关闭。

我甚至尝试使用error_reporting(0);函数来压制所有错误（是的，我知道这不是一个好主意），看看它是否允许我的网站显示在Windows机器上，但仍然是错误显示了！这非常令人沮丧，所以我想知道如何解决这个问题。

这是我的cart.php代码：

<?php

session_start();

$page = 'index.php';

mysql_connect('localhost','root','') or die(mysql_error());
mysql_select_db('cart') or die(mysql_error());

if (isset($_GET['add'])) {
    $quantity = mysql_query('SELECT id, quantity FROM products WHERE id='.mysql_real_escape_string((int)$_GET['add']));
while ($quantity_row = mysql_fetch_assoc($quantity)) {
    if ($quantity_row['quantity']!=$_SESSION['cart_'.(int)$_GET['add']]) {
        $_SESSION['cart_' . (int)$_GET['add']] +='1';
        header('Location: order.php');

    }
}
header('Location: order.php');

}

if (isset($_GET['remove'])) {
    $_SESSION['cart_'.(int)$_GET['remove']]--;
    header ('Location: order.php');

}

    $_SESSION['cart_' . (int)$_GET['delete']]='0';
    header ('Location: order.php');

    $get = mysql_query('SELECT id, name, description, price FROM products WHERE quantity > 0 ORDER BY id ASC');

Answer 1

如上所述，您的PHP解析器似乎没有正确读取短标签。对于评论者，我没有试图窃取答案，我只是将代码粘贴到NetBeans中，然后在那里进行了更正。

PS。 Netbeans是一个很好的调试工具，可以很容易地帮助你！它是免费下载的，当您使用PHP项目时非常棒。

将第59行从<?更改为<?php，文件应继续向下读到最后。

Answer 2

只需将<?更改为<?php即可。使用以下代码

<?php

session_start();

$page = 'index.php';

mysql_connect('localhost','root','') or die(mysql_error());
mysql_select_db('cart') or die(mysql_error());

if (isset($_GET['add'])) {
    $quantity = mysql_query('SELECT id, quantity FROM products WHERE id='.mysql_real_escape_string((int)$_GET['add']));
while ($quantity_row = mysql_fetch_assoc($quantity)) {
    if ($quantity_row['quantity']!=$_SESSION['cart_'.(int)$_GET['add']]) {
        $_SESSION['cart_' . (int)$_GET['add']] +='1';
        header('Location: order.php');

    }
}
header('Location: order.php');

}

if (isset($_GET['remove'])) {
    $_SESSION['cart_'.(int)$_GET['remove']]--;
    header ('Location: order.php');

}

if (isset($_GET['delete'])) {
    $_SESSION['cart_' . (int)$_GET['delete']]='0';
    header ('Location: order.php');
}



function products() {
    $get = mysql_query('SELECT id, name, description, price FROM products WHERE quantity > 0 ORDER BY id ASC');
    if (mysql_num_rows($get) == 0) {
        echo "There are no products to display.";
    }
    else {
        echo "<center>\n";
