如何创建 PHP 函数库并将其部署到云端?

如何创建 PHP 函数库并将其部署到云端

创建函数库

  1. 使用 Composer 创建一个新的 PHP 项目:
composer init
  1. 创建一个 src/FunctionLibrary.php 文件,并在其中定义函数:
<?php

function my_function($param1, $param2): string
{
    return "Hello from my function: $param1, $param2";
}
  1. composer.json 文件中添加函数库元数据:
{
    "name": "my-function-library",
    "type": "library",
    "autoload": {
        "psr-4": {
            "MyFunctionLibrary\\": "src/"
        }
    }
}

部署到云端

使用 AWS Lambda

  1. 创建一个新的 AWS Lambda 函数:
  • 在 AWS 控制台中转到 Lambda 服务。
  • 单击“创建函数”。
  • 选择“从头开始创建函数”。
  1. 为函数命名并选择“Python 3.8”作为运行时。
  2. 在代码编辑器中,将函数库源代码复制并粘贴到 handler.py 文件中。
  3. 部署函数。

使用 Google Cloud Functions

  1. 创建一个新的 Google Cloud Function:
  • 在 Google Cloud 控制台中转到 Cloud Functions 服务。
  • 单击“创建函数”。
  • 选择“HTTP”作为触发器。
  1. 函数名称和区域。
  2. 在代码编辑器中,选择“PHP 7”作为运行时。
  3. 将函数库源代码复制并粘贴到 index.php 文件中。
  4. 部署函数。

实战案例

假设我们希望使用函数库中的 my_function() 函数来处理表单提交:

PHP 代码

<?php

use MyFunctionLibrary\FunctionLibrary;

$name = $_POST['name'];
$email = $_POST['email'];

$result = FunctionLibrary::my_function($name, $email);

echo $result;

HTML 表单

<form action="submit.php" method="post">
    <input type="text" name="name" placeholder="Name">
    <input type="email" name="email" placeholder="Email">
    <input type="submit" value="Submit">
</form>

部署后的效果

当用户提交表单时,PHP 代码将使用部署在云端的函数库中的 my_function() 函数处理提交,并打印结果。
