How do PHP functions interoperate with other languages ​​and frameworks?

PHP is interoperable across languages ​​and frameworks, including interaction with other languages ​​(such as C, Python) and interaction with frameworks such as Laravel and Django. These interactions are achieved by calling C functions, executing Python scripts, using the framework's Facade, or loading the Django ORM. Practical examples show how to interoperate PHP with JavaScript to calculate products by executing JavaScript functions. These technologies enhance application functionality and simplify development.

Guide to interoperability of PHP functions across languages ​​and frameworks

As a highly extensible language, PHP provides a wealth of methods to interact with other programming Languages ​​and frameworks interoperate. This article will provide a concise and easy-to-understand guide to help you master these interactive technologies, and show a practical example.

Interact with other languages

Use PHP to call C functions

<?php
// 加载 C 头文件
#include "myheader.h"

// 调用 C 函数
$result = my_function(10, 20);

// 打印结果
echo $result;
?>

Use PHP to call Python scripts

<?php
// 调用 Python 解释器
$python = 'python';

// 执行 Python 脚本
$output = shell_exec("$python myscript.py 10 20");

// 处理输出
$result = trim($output);
echo $result;
?>

Interoperate with frameworks

Interacting with the Laravel framework

<?php
// 使用 Laravel 的 Facade
use Illuminate\Support\Facades\DB;

// 执行查询
$users = DB::table('users')->get();

// 遍历结果
foreach ($users as $user) {
    echo $user->name;
}
?>

Interacting with the Django framework

<?php
// 加载 Django ORM
require_once('djangoproject/settings.py');

// 建立 Django ORM 连接
$settings = DjangoSettings()

// 执行查询
$users = User.objects.all()

// 遍历结果
foreach ($users as $user) {
    echo $user.username;
}
?>

Practical case: interoperating PHP with JavaScript

Goal:In the PHP backend Call a JavaScript function to calculate the product of two numbers.

Steps:

1. Create the following code in the PHP backend:

<?php
// 加载 JavaScript 文件
$js_code = file_get_contents('multiply.js');

// 执行 JavaScript 代码并获取结果
$result = run_javascript($js_code, [10, 20]);

// 打印结果
echo $result;

function run_javascript($js_code, $args) {
    // 创建 JavaScript 引擎
    $engine = create_javascript_engine();

    // 设置全局变量
    set_javascript_global($engine, 'args', $args);

    // 执行 JavaScript 代码
    eval_javascript($engine, $js_code);

    // 获取结果
    return get_javascript_global($engine, 'result');
}

2. In multiply Write JavaScript function in .js:

// JavaScript 函数计算两个数字的乘积
function multiply(args) {
    const num1 = args[0];
    const num2 = args[1];

    // 将结果存储在全局变量中
    result = num1 * num2;
}

Run this code, the PHP backend will successfully call the JavaScript function and print the product result.

Through the above technologies, you can easily achieve interoperability between PHP and different languages ​​​​and frameworks, enhance your application functionality and simplify the development process.
