PHP is one of the most popular scripting languages today, with many PHP integrations across platforms, including WordPress.
To run PHP scripts and web applications, developers first need to start a PHP server. Of course, there are many methods for starting a PHP server. However, it’s crucial to choose the best one for your needs.
While you can set up your own server, it often makes sense to choose a reliable PHP hosting provider, like A2 Hosting. The provider will host your PHP applications on their pre-configured servers, and will manage server details, PHP installation, and other features.
Today, we’ll cover everything you need to know to start a PHP server, discuss some of the most common PHP errors, and list the best practices for a PHP server. But first, let’s see what a PHP server is.
What Is a PHP Server?
A PHP server is a web server that provides a platform for running PHP applications. It’s designed to handle PHP requests and execute PHP scripts. In addition, it is responsible for receiving HTTP requests from clients, interpreting them, and returning responses.
Some PHP servers have additional functionalities and include:
- Clustering services
- Automated application monitoring tools
- Web server configuration
Why Do You Need a PHP Server?
You will need a PHP server if you want to run PHP scripts and develop PHP applications. This is because PHP is a server-side scripting language executed on the server side, not the client side.
- Additionally, PHP servers with built-in tools can significantly help developers because they can reduce the need for additional third-party products, decreasing costs
- PHP servers can boost efficiency by enabling smooth workflows running from one browser window
Setting Up a PHP Server
Now that we’ve covered the basics of PHP servers and their use, we can move on to the setup process. Here’s an outline of how to set up a PHP server:
1. Install PHP
The first step is to install PHP on your system. You can download PHP from the official website or install it via a package manager on Linux.
- After installing it, you need to create a new PHP folder in the root of your C: \ drive
- Then, extract the contents of the PHP zip into your C: \ drive
- Of course, you can install PHP anywhere on your system, not just on your C: \ drive
2. Install a Web Server
After installing PHP, you need to install a web server. This web server will host your PHP files. Some of the most popular options include Apache, Nginx, and Microsoft IIS.
3. Configure the Web Server
Once you have installed the web server, you must configure it to work with PHP. This usually involves adding some configuration files to your web server’s directory.
4. Start the PHP Server
After installing and configuring PHP and your web server, you can start the PHP server by running a command in the terminal.
- To start the PHP server, use the command php -S localhost:8000 in the terminal
- You can visit the site by using localhost:8000 as the URL across all browsers
5. Test the Server
You should test the PHP server by creating a simple PHP file and checking that you can access it via the web server.
- Create a test script using the phpinfo() function and save the file as phptest.php in the web server document root
- Then, to ensure that the web server is running, open a browser and type http://server-ip/phptest.php
- If the web server is running, your screen will show details about which PHP version you use and all the modules you have installed
6. Additional Configurations
You can further configure your PHP server to suit your needs. For example, you can Change the PHP configuration settings, configure SSL, and set up virtual hosts.
Starting a PHP Server
Now, it’s time to start your PHP server. Here’s what you need to do:
1. Install PHP on Your Computer
If you haven’t already, download and install PHP on your computer. You can download PHP from the official website.
2. Create a PHP File
Create a new file with the .php extension. Most PHP files are saved within a folder in a web server’s public directory or a web root directory.
- For example, you can create a new PHP file and name it index.php. This will be the file that you will run on the server
- If you save the file as index.php in your web root directory, you can access it by typing either http://www.example.org or http://www.example.org/index.php
3. Open a Command Prompt
How you open a command prompt or terminal on your computer depends on your operating system.
- For Windows, click on the Start option and type in Command Prompt. You can also open a command prompt by pressing Ctrl+r on your keyboard. Then, type cmd and press OK.
- For MacOS, open the Launchpad and type in the terminal.
- For Linux, it depends on which interface you use, like GNOME, KDE, and Xfce. This is because you access the terminal in different ways for each interface.
4. Navigate to the Directory With the PHP File
You can use the cd command to navigate to the directory where your PHP file is saved. In addition, it allows you to move between directories.
- To find the exact file you’re looking for, type in cd your-directory
5. Start the PHP Server
To start the PHP server on your computer, type in the php -S localhost:8000 command in the command prompt.
- It treats the current directory as the document root directory. If the request does not specify a file, index.php or index.html in the given directory will be displayed.
- To specify a document root directory, use the php -S localhost:8000 –t command and type in the directory you wish after the –t.
6. Test the Server
To test the server, open any browser you wish, type in http://localhost:8000, and press Enter. If you see the contents of your PHP file displayed in the browser, it means your server is running correctly.
7. Stop the Server
To stop the PHP server, you only need to press Ctrl+C in the command prompt. This will prevent the PHP server from running.
Troubleshooting Common Errors While Starting a PHP Server
From PHP errors in WordPress to every other platform, there are many errors than can occur at any stage of development. Here are some common errors that you may encounter while starting a PHP server and some possible solutions:
1. Port Already in Use
This error occurs when another program is already using the port you are trying to use. You can try using a different port number to fix this issue.
- To specify a port number, you can use the –p option. For instance, you can change the php -S localhost:8000 to php -S localhost:8080
2. PHP File Not Found
The PHP file not found error usually occurs due to a permissions error or because some configuration file details are incorrect.
- To fix this issue, make sure that the file exists in the correct directory
- Also, ensure that you are specifying the correct path in your URL
3. Server Not Responding
If your PHP server is not responding or is taking too long to load, check the server logs for any errors.
- Additionally, it would be best if you tried restarting the server
- If this doesn’t help, check your Internet connection and restart your router
4. Server Not Starting
If your PHP server is not starting at all, then you should:
- Check which PHP version you have installed to ensure that it is the correct one
- Ensure that you are running the server command from the correct directory
5. Access Denied
If you get an access denied error while trying to access a file through the server, ensure the file has the correct permissions set.
- You can change the file permissions by using the chmod command
6. Invalid PHP Syntax
If you get an error message indicating a syntax error in your PHP code, you should check your code for any issues or typos.
- You can also use a PHP syntax checker or IDE to help you find and fix errors
7. PHP Extensions Missing
You may get an error message indicating that an extension is missing if you use PHP extensions in your code that are not installed on your server.
- You can install the missing extension via your server’s package manager to fix this issue. You can also manually download and install the missing extension
