我正在尝试计算文件的下载量。一旦客户端点击链接在txt文件中写入用户名和路径以及计数。
我的问题是:我如何才能将相同的用户以及他们互相点击的内容组合在一起,因为现在我得到的却没有订单:
用户名:Lee |下载次数:50 |文件已下载:/我们的产品/ 88系列led-wall-light
用户名:Nour |下载次数:50 |文件已下载:/我们的产品/ 88系列led-wall-light
用户名:Lee |下载次数:50 |文件已下载:/我们的产品/ 88系列led-wall-light
用户名:X |下载次数:50 |文件已下载:/我们的产品/ 88系列led-wall-light
用户名:Lee |下载次数:50 |文件已下载:/我们的产品/ 88系列led-wall-light

单个文件版本
考虑到评论中的一些建议,我会做这样的事情。
您可以将序列化的信息存储在文件中,这样您就可以轻松地将其恢复为php变量。
我不会存储“计数”,因为如果您有下载的项目列表,那么这是一个冗余信息。您可以随时计算该数组。
首先,我运行此脚本以使用您提供的数据初始化文件。
<?php
// Only first time to load initial data in file
$data = [
'Lee' => [
'files' => [
'/our-products/88-series-led-wall-light',
'/our-products/88-series-led-wall-light',
'/our-products/88-series-led-wall-light'
]
],
'Nour' => [
'files' => [
'/our-products/88-series-led-wall-light'
]
],
'X' => [
'files' => [
'/our-products/88-series-led-wall-light'
]
]
];
$file = 'countClick_images.txt';
file_put_contents($file, serialize($data));
这会生成一个包含此序列化数据的文件:
a:4:{s:3:"Lee";a:1:{s:5:"files";a:3:{i:0;s:38:"/our-products/88-series-led-wall-light";i:1;s:38:"/our-products/88-series-led-wall-light";i:2;s:38:"/our-products/88-series-led-wall-light";}}s:4:"Nour";a:1:{s:5:"files";a:1:{i:0;s:38:"/our-products/88-series-led-wall-light";}}s:1:"X";a:1:{s:5:"files";a:1:{i:0;s:38:"/our-products/88-series-led-wall-light";}}s:8:"testUser";a:1:{s:5:"files";a:1:{i:0;s:10:"/test/file";}}}
之后,我修改了您的脚本以使用serialize()
和unserialize()
。
$storeFile = 'countClick_images.txt';
// I forced some GET data here to try
$_GET['username'] = 'testUser';
$_GET['path'] = '/test/file';
if (isset($_GET['username']) && isset($_GET['path'])) {
$username = $_GET['username'];
$downloadedFile = $_GET['path'];
if (file_exists($storeFile)) {
$data = unserialize(file_get_contents($storeFile));
} else {
$data = [];
}
echo "Data before:\n" . print_r($data,1);
// This creates a particular user data structure
// I put the files array into a 'files' key for you to be able to store more information of that user
if (!isset($data[$username])) {
$data[$username] = ['files' => []];
}
$data[$username]['files'][] = $downloadedFile;
echo "Data after:\n" . print_r($data,1);
// This creates the file if it doesn't exist
file_put_contents($storeFile, serialize($data));
}
另外,我认为将每个用户存储在一个文件中是个好主意,以避免在有很多用户和下载时使用大文件。

多文件版本(也使用用户ID而不是用户名作为索引)
我制作了第二个版本,我将如何真正做到这一点,以避免潜在的问题:巨大的单个文件和糟糕的用户名。
此脚本使用您提供的初始数据生成三个不同的文件,每个用户一个文件。
<?php
// Only first time to load initial data in file
$data = [
'1' => [
'username' => 'Lee',
'files' => [
'/our-products/88-series-led-wall-light',
'/our-products/88-series-led-wall-light',
'/our-products/88-series-led-wall-light'
]
],
'2' => [
'username' => 'Nour',
'files' => [
'/our-products/88-series-led-wall-light'
]
],
'3' => [
'username' => 'X',
'files' => [
'/our-products/88-series-led-wall-light'
]
]
];
foreach ($data as $userId => $userData) {
$fileName = 'countClick_images_user_' . $userId . '.txt';
file_put_contents($fileName, serialize($userData));
}
现在你有了这些文件:
countClick_images_user_1.txt
countClick_images_user_2.txt
countClick_images_user_3.txt
之后,添加新下载的脚本如下所示:
<?php
$_GET['userid'] = '4';
$_GET['path'] = '/test/file';
$_GET['username'] = 'testUser'; // You need this input name only first time a user downloads something
if (isset($_GET['userid']) && isset($_GET['username']) && isset($_GET['path'])) {
// You can add more controls here to validate input data
$userId = $_GET['userid'];
$userName = $_GET['username'];
$downloadedFile = $_GET['path'];
$storeFile = 'countClick_images_user_' . $userId . '.txt';
if (file_exists($storeFile)) {
$data = unserialize(file_get_contents($storeFile));
} else {
$data = [];
}
echo "Data before:\n" . print_r($data,1);
// Here you create data structure
if (!isset($data['username'])) {
$data['username'] = $userName;
$data['files'] = [];
}
$data['files'][] = $downloadedFile;
echo "Data after:\n" . print_r($data,1);
file_put_contents($storeFile, serialize($data));
}
首次运行时,它会为用户4创建一个新文件,创建数据结构,添加第一个下载并将其存储到文件中。
如果再次运行,它会获取用户4文件的数据,添加新的下载并将其再次存储在文件中。
输出所有用户信息:
<?php
// Format:
// * username: nour | clicks: 55 | files: file1, file2, file3 * lee | clicks 5| files: file1, file3 * x | clicks 22| files: file3
// glob returns an array with all file names that match that pattern
foreach (glob("countClick_images_user_*.txt") as $storeFile) {
$userData = unserialize(file_get_contents($storeFile));
echo "username: " . $userData['username'] . " | ";
echo "clicks: " . count($userData['files']) . " | ";
echo "files: " . implode(",", $userData['files']);
echo "\n";
}
这将输出:
username: Lee | clicks: 3 | files: /our-products/88-series-led-wall-light, /our-products/88-series-led-wall-light, /our-products/88-series-led-wall-light username: Nour | clicks: 1 | files: /our-products/88-series-led-wall-light username: X | clicks: 1 | files: /our-products/88-series-led-wall-light username: testUser | clicks: 2 | files: /test/file, /test/file
