How to use Go language in PHP programming?

As the importance of web applications continues to increase in web development, multi-threaded programming has gradually become a more common method. However, the traditional PHP language and some other popular back-end languages ​​are not always able to meet the needs of web application development. Therefore, both front-end and back-end developers are looking for a more efficient and scalable way to meet these needs. In such an environment, the Go language has become increasingly popular because it is fast and easy to write, and it also supports high concurrency and multi-threaded programming. Therefore, this article will introduce how to use Go language in PHP programming.

Why use Go language?

Go language is a programming language developed by Google. It is designed as a language for network programming and distributed computing. The Go language is known for its efficiency, speed, and low memory usage. It is currently one of the most suitable back-end languages ​​for implementing highly available web applications. Here are some advantages of using Go language:

1. Efficiency: The compiler of Go language is very fast and the code can be written quickly and easily due to the simplicity of its syntax rules.

2. Extensible! The Go language provides an easy-to-extend way to quickly scale our applications when demand grows rapidly. Due to its efficient memory usage, it can handle a large number of requests with ease.

3. High concurrency: For web applications, high concurrency is a must-have advantage. Go language can use goroutines to achieve high concurrency, and its performance is better than other existing programming languages.

4. Simplicity of multi-threaded programming: Because the Go language uses goroutines for concurrent programming, this makes its multi-threaded programming very simple.

How to use Go language in PHP?

Go is not a very popular language for most PHP developers, so they may not know how to apply it to their work. Of course, we don't need to completely abandon the PHP language to use Go. We can use the interface between PHP and Go language to achieve interaction between the two.

Using Go in PHP can be achieved through CGO and PHP extensions. CGO is a feature of the Go language that allows us to interact with the C language. In order to use CGO, we first need to install the Go development environment. Then, we need to introduce the CGO library into the Go code and add CGO-related code to the Go code.

To use the Go language in PHP, we first need to create a Go program and compile it into a shared library using CGO. This shared library can be used in PHP. Next, we will write code in PHP to load and execute this shared library.

The following is a simple example showing how to use Go language in PHP code.

First, we need to write a toy program in Go, such as printing some text:

package main

import "C"
import "fmt"

//export PrintText
func PrintText(text *C.char) {
    fmt.Println(C.GoString(text))
}

func main() {}

In this program, we define a Go function called PrintText, which converts a C .char string printed to standard output.

Then, we need to compile this program into a shared library. We can accomplish this using the following command:

go build -buildmode=c-shared -o libhello.so hello.go

In this command, we used the -buildmode=c-shared option, which tells the Go compiler to compile the program into a shared library.

Next, we can use this shared library in PHP code and call the functions inside. Here is an example of PHP code:

<?php
$lib = './libhello.so';
$text = "Hello from Go!";
$function = 'PrintText';
$output = null;

if (!extension_loaded('ffi')) {
    throw new Exception('FFI extension not found');
}

// Load Go shared library
$ffi = FFI::cdef("
    void $function(char* text);
", $lib);

// Call Go function
$ffi->$function($text);

// Output
echo $output;

In this example, we load Go's shared library by using PHP's built-in FFI extension. Then, we called the function PrintText in the Go program and passed it the $text string as a parameter.

Finally, we output the results to standard output.

Summary

While using Go in PHP code can be a bit tedious, it is an approach worth exploring. By using Go's efficiency and scalability, we can implement a high-performance web application. If you are a PHP developer and are looking for a more efficient and scalable programming language, then you should consider using Go for your projects.
