To run the PHP website on your local computer, you need to install PHP and Apache. Windows users download Apache and configure httpd.conf, then download PHP and modify the configuration file to load the PHP module; macOS/Linux users can use Homebrew or apt command to install. Finally, create an info.php file in the root directory of the website and test whether it is successful.

Want to run a PHP website on your local computer? The most basic and most commonly used combination is to install PHP and Apache. Although it sounds a bit technical, it is not difficult to deal with it as long as you take it step by step.

Preparation before installation: Confirm the system environment

Before you start, confirm what operating system you are using. Windows, macOS or Linux, the installation methods of different systems are slightly different. In addition, it is recommended that you close other programs that may occupy port 80 (such as IIS or some proxy software), otherwise Apache startup will fail.

If you are new to you, you can consider using integration packages such as XAMPP or WAMP, which have already helped you with Apache, PHP and MySQL, which saves a lot of trouble. However, if you want to configure it manually, the following steps are more applicable.

How to install Apache and PHP in Windows

Apache is not natively supported on Windows, but can be run through manual configuration. The following is the basic process:

• Download Apache: Go to the official website or a reliable mirroring site to download the Windows version of Apache (such as ApacheHaus or Apache Lounge)

  

• After decompression, put it in a fixed directory, such as C:\Apache24

• Modify the configuration file httpd.conf to ensure the path is correct, and set the listening port (default is 80)

• Test start: Open the command line, enter the bin directory of Apache, and run httpd.exe . If there is no error, it means that the configuration is fine.

• Next, download the PHP Windows zip package and extract it to a directory similar to C:\php

• Change php.ini-development php.ini , then modify the Apache configuration file and load the PHP module, for example:

   LoadModule php_module "c:/php/php8apache2_4.dll"
  AddHandler application/x-httpd-php .php
  PHPIniDir "C:\php"

Don't forget to add PHP to the system environment variables, so that you can use the php command directly on the command line.

macOS/Linux installation is easier

If you are using Linux systems like macOS or Ubuntu, it will be much easier to install.

• macOS can be executed using Homebrew:

   brew install httpd
  brew install php

• Linux (Ubuntu) can be used with apt:

   sudo apt update
  sudo apt install apache2
  sudo apt install php libapache2-mod-php

After the installation is completed, Apache will usually start automatically. You can use your browser to access http://localhost to test whether you see the default page.

Also pay attention to the location of the PHP configuration file, usually in /etc/php/版本號(hào)/apache2/php.ini . If you need to adjust the upload limit or enable the extension, just change it here.

Test your configuration

No matter which system you want, don't forget to do a simple test in the end. Create a new info.php file in the root directory of the website (such as /var/www/html or htdocs ), with the following content:

 <?php phpinfo(); ?>

After saving, visit http://localhost/info.php in your browser. If you can see the PHP information page, it means that Apache and PHP have successfully linked.

If you encounter an error, the most common problems are port conflicts, insufficient permissions, or module not loading. At this time, looking at Apache's log files (usually logs/error.log ) can help you quickly locate problems.

Basically that's it. After the configuration is complete, you can start writing PHP pages.
