Cloud integration for PHP cross-platform applications

This tutorial guides the development of cross-platform PHP applications using cloud storage. First, create a PHP application and integrate Google Cloud or AWS services. Next, establish a connection to cloud storage and upload and download files through the API. Finally, the sample app demonstrates image uploading to Google Cloud Storage.

Cloud Integration of PHP Cross-Platform Applications

Cross-platform application development allows developers to build and deploy applications on multiple platforms and devices to maximize Improve code reusability and simplify maintenance. This tutorial will guide you on how to use PHP and cloud services to easily create cross-platform applications.

1. Create a PHP application

Create a new PHP application and add the necessary classes and methods. If you are using Composer, you can install the necessary libraries.

// composer.json
{
    "require": {
        "google/cloud-platform": "~1.0"
    }
}

2. Cloud integration

Google Cloud

##Go to [Google Cloud Console](https://console.cloud.google .com/) to create a project.
Enable [Cloud Storage API](https://console.cloud.google.com/apis/dashboard).
Get [Service Account Credentials](https://console.cloud.google.com/apis/credentials).

AWS

Go to [AWS Management Console](https://console.aws.amazon.com/) to create an account.
Enable [S3 API](https://console.aws.amazon.com/iam/home#/roles).
Create access keys ([IAM users](https://console.aws.amazon.com/iam/home#/users)).

3. Connect to cloud storage

Google Cloud

use Google\Cloud\Storage\StorageClient;

// 实例化存储客户端
$storage = new StorageClient([
    'projectId' => '<YOUR_PROJECT_ID>',
    'keyFilePath' => '<SERVICE_ACCOUNT_PATH>'
]);

// 使用 bucket
$bucket = $storage->bucket('<YOUR_BUCKET_NAME>');

AWS

use Aws\S3\S3Client;

// 实例化 S3 客户端
$s3 = new S3Client([
    'version' => 'latest',
    'region' => '<YOUR_REGION>',
    'credentials' => [
        'key' => '<YOUR_ACCESS_KEY_ID>',
        'secret' => '<YOUR_SECRET_ACCESS_KEY>'
    ]
]);

// 使用桶
$bucket = $s3->bucket('<YOUR_BUCKET_NAME>');

4. Upload and download files

File upload

// 上传文件到存储桶
$bucket->upload('<本地文件名>', [
    'name' => '<远程文件名>'
]);

File download

// 从存储桶下载文件
$bucket->download('<远程文件名>', '<本地文件名>');

Example

Sample Application: Image Upload

This is a simple PHP application that allows users to upload images to cloud storage:

<?php
// 包含库
require 'vendor/autoload.php';

// 创建 Google Cloud 存储客户端
$storage = new StorageClient([
    'projectId' => '<YOUR_PROJECT_ID>',
    'keyFilePath' => '<SERVICE_ACCOUNT_PATH>'
]);

// 上传图像到存储桶
if (isset($_FILES['image'])) {
    $file = $_FILES['image'];
    $bucket->upload($file['tmp_name'], [
        'name' => $file['name']
    ]);
}
?>

<!-- HTML 表单 -->
<form action="" method="post" enctype="multipart/form-data">
    <input type="file" name="image">
    <input type="submit" value="上传">
</form>

The application allows users to upload images from HTML forms, and upload it to Google Cloud storage.
