With the continuous development and updating of technology, we often encounter the need to run different applications or programming languages ​​on a server. Among them, NodeJS and PHP are very popular server-side programming languages. However, sometimes we may need to run both languages ​​on the same server. This article will introduce how to run NodeJS on a PHP server.

  1. Install NodeJS

Before running NodeJS on the PHP server, we need to install NodeJS on the server first. Installation of NodeJS is very simple, just open a terminal window and enter the following command:

sudo apt-get install nodejs

This will automatically install the latest version of NodeJS on your server.

  1. Install PHP

If PHP is not installed on your PHP server, you need to install PHP first. Use the following command to install PHP on your Ubuntu server:

sudo apt-get install php

If your server is using a different operating system, you will need to use a different installation command to install PHP.

  1. Install PHP's exec() function extension

To run NodeJS in PHP, we need to use PHP's exec() function to execute NodeJS scripts. But by default, PHP's exec() function may be disabled or subject to other restrictions. Therefore, we need to install PHP's exec() function extension.

Use the following command to install PHP's exec() function extension on the Ubuntu server:

sudo apt-get install php-exec

If your server uses another operating system, you need to use a different installation command to install PHP exec() function extension.

  1. Create NodeJS script

Now that we have installed NodeJS and PHP, and can use the exec() function in PHP, next we need to create a simple NodeJS Script to test whether it can run on the PHP server.

Create a file named test.js and enter the following content:

console.log('Hello from NodeJS!');

Save and close the file.

  1. Execute NodeJS script

Now we are ready to run the NodeJS script. We can run NodeJS scripts through PHP's exec() function.

In PHP code, we can use the following code to execute the NodeJS script:

$output = exec('nodejs /path/to/test.js');
echo $output;

Here, we use the exec() function to execute the command "nodejs /path/to/test.js" , where "/path/to/test.js" is the path to the NodeJS script you just created. After the command is successfully executed, "Hello from NodeJS!" will be output to the PHP page.

  1. Using the Express Framework

To run more complex NodeJS applications on a PHP server, we can use the Express framework. First, you need to install Express globally using the following command:

sudo npm install -g express-generator

Then, in your project directory, use the following command to create an Express project:

express myproject

After executing the above command, you will have Create a new Express project in the project directory.

Next, we need to go into the project directory and install the required dependencies:

cd myproject
npm install

With the dependencies ready, we can start the Express application using the following command:

npm start

Now, your Express application is running on the NodeJS server. By default, the Express application will run on port 3000. We can open http://localhost:3000 in the browser to view the application.

  1. Integrating NodeJS Application with PHP

Now we have the NodeJS application running on the NodeJS server and can view it in the browser. However, we still need to integrate it into the PHP server.

To do this, we need to use the exec() function in the PHP file to start the NodeJS server. In PHP code, you can use the following code to start the NodeJS server:

exec('nohup nodejs /path/to/nodejs/app.js > /dev/null 2>&1 &');

Here, "/path/to/nodejs/app.js" is the path to your NodeJS application. After executing the above code, the NodeJS server will be started in the background.

Now we have integrated the NodeJS application with the PHP server. We can add JavaScript code and NodeJS modules to PHP pages to extend the functionality of PHP applications. For example, you can use NodeJS's Redis module to extend caching capabilities in PHP.

By analogy, we can use the above steps to run any NodeJS application on the PHP server and extend the functionality and performance of the PHP application.

Summary

NodeJS and PHP are two powerful server-side programming languages ​​that can help us develop colorful network applications. In this article, we introduced how to run NodeJS on a PHP server and integrate it into a PHP application. Using the steps above, you can extend the functionality and performance of your PHP application while also exploring the features and benefits of NodeJS.
