PHP が MongoDB を使用して分散ファイル ストレージを実装する方法

<?php
require_once __DIR__ . "/vendor/autoload.php";

$uri = "mongodb://localhost:27017";
$manager = new MongoDBDriverManager($uri);

// 验证是否连接成功
if ($manager) {
    echo "成功连接MongoDB！";
} else {
    echo "连接MongoDB失败！";
}

<?php
require_once __DIR__ . "/vendor/autoload.php";

$uri = "mongodb://localhost:27017";
$manager = new MongoDBDriverManager($uri);

// 存储文件
$file = "path/to/myfile.txt";
$stream = fopen($file, "r");
$options = [
    "filename" => "myfile.txt",
    "contentType" => "text/plain"
];
$bucket = new MongoDBGridFSBucket($manager, "mydatabase");
$id = $bucket->uploadFromStream($options, $stream);

// 输出上传文件的ID
echo "上传文件的ID：" . $id;

<?php
require_once __DIR__ . "/vendor/autoload.php";

$uri = "mongodb://localhost:27017";
$manager = new MongoDBDriverManager($uri);

// 获取文件
$fileID = "5f7b26d8c235dbc5a1ec8b90";
$bucket = new MongoDBGridFSBucket($manager, "mydatabase");
$stream = $bucket->openDownloadStream(new MongoDBBSONObjectID($fileID));

// 输出文件内容
echo stream_get_contents($stream);

<?php
require_once __DIR__ . "/vendor/autoload.php";

$uri = "mongodb://localhost:27017";
$manager = new MongoDBDriverManager($uri);

// 删除文件
$fileID = "5f7b26d8c235dbc5a1ec8b90";
$bucket = new MongoDBGridFSBucket($manager, "mydatabase");
$bucket->delete(new MongoDBBSONObjectID($fileID));

// 输出成功删除的文件ID
echo "成功删除文件ID：" . $fileID;
