Why PHP?

PHP remains the most widespread and popular server-side programming language on the Web. It’s installed by most web hosts, and has a simple learning curve, close ties with the MySQL database, superb documentation, and a wide collection of libraries to cut your development time. PHP may not be perfect, but you should consider it for your next web application. It’s the language of choice for Facebook, Slack, Wikipedia, MailChimp, Etsy, and WordPress (the content management system which powers almost 45% of the web).

Why Install PHP Locally?

Installing PHP on your development PC allows you to create and test websites and applications without affecting the data or systems on your live server.

Alternative Installation Options

Before you jump in, there may be a simpler installation options…

Using an all-in-one package

All-in-one packages are available for Windows. They contain Apache, PHP, MySQL, and other useful dependencies in a single installation file. These packages include XAMPP, WampServer and Web.Developer.

These packages are easy to use, but they may not match your live server environment. Installing Apache and PHP manually will help you learn more about the system and configuration options.

Using a Linux virtual machine

Microsoft Hyper-V (provided in Windows Professional) and VirtualBox are free hypervisors which emulate a PC so you can install another operating system.

You can install any version of Linux, then follow its Apache and PHP installation instructions. Alternatively, distros such as Ubuntu Server provide them as standard (although they may not be the latest editions).

Using Windows Subsystem for Linux 2

WSL2 is also a virtual machine, but it’s tightly integrated into Windows so activities such as file sharing and localhost resolution are seamless. You can install a variety of Linux distros, so refer to the appropriate Apache and PHP instructions.

Using Docker

Docker creates a wrapper (known as a container) around pre-configured application dependencies such as Apache, PHP, MySQL, MongoDB, and most other web software. Containers look like full Linux Virtual Machines but are considerably more lightweight.

Docker is currently considered the best option for setting up a PHP development environment. Check out SitePoint’s article Setting Up a Modern PHP Development Environment with Docker for a complete guide to setting it up.

Installing Apache (optional)

The following sections describe how to install Apache and PHP directly on Windows.

PHP provides a built-in web server, which you can launch by navigating to a folder and running the PHP executable with an -S parameter to set the localhost port. For example:

cd myproject php -S localhost:8000 

You can then view PHP pages in a browser at http://localhost:8000.

This may be adequate for quick tests, but your live server will use Apache or similar web server software. Emulating that environment as closely as possible permits more advanced customization and should prevent development errors.

To install Apache, download the latest Win64 ZIP file from https://www.apachelounge.com/download/ and extract its Apache24 folder to the root of your C: drive. You’ll also need to install the Visual C++ Redistributable for Visual Studio 2015–2020 ( vc_redist_x64 ); the page has a link at the top.

Open a cmd command prompt (not PowerShell) and start Apache with:

You may need to accept a firewall exception before the server starts to run. Open http://localhost in a browser and an “It works!” message should appear. Note:

• C:\Apache24\conf\httpd.conf is Apache’s configuration file if you need to change server settings.
• C:\Apache24\htdocs is the web server’s root content folder. It contains a single index.html file with the “It works!” message.

If Apache fails to start, another application could be hogging port 80. (Skype is the prime candidate, and the Windows app won’t let you disable it!) If this occurs, edit C:\Apache24\conf\httpd.conf and change the line Listen 80 to Listen 8080 or any other free port. Restart Apache and, from that point onward, you can load web files at http://localhost:8080.

Stop the server by pressing Ctrl + C in the cmd terminal. The ReadMe file in the ZIP also provides instructions for installing Apache as a Windows service so it auto-starts on boot.

Installing PHP

Install PHP by following the steps below. Note that there’s more than one way to configure Apache and PHP, but this is possibly the quickest method.

Step 1: Download the PHP files

Get the latest PHP x64 Thread Safe ZIP package from https://windows.php.net/download/.

Step 2: Extract the files

Create a new php folder in the root of your C:\ drive and extract the content of the ZIP into it.

You can install PHP anywhere on your system, but you’ll need to change the paths referenced below if you use anything other than C:\php .

Step 3: Configure php.ini

PHP’s configuration file is php.ini . This doesn’t exist initially, so copy C:\php\php.ini-development to C:\php\php.ini . This default configuration provides a development setup which reports all PHP errors and warnings.

You can edit php.ini in a text editor, and you may need to change lines such as those suggested below (use search to find the setting). In most cases, you’ll need to remove a leading semicolon ( ; ) to uncomment a value.

First, enable any required extensions according to the libraries you want to use. The following extensions should be suitable for most applications including WordPress:

extension=curl extension=gd extension=mbstring extension=pdo_mysql 

If you want to send emails using PHP’s mail() function, enter the details of an SMTP server in the [mail function] section (your ISP’s settings should be suitable):

[mail function] ; For Win32 only. ; http://php.net/smtp SMTP = mail.myisp.com ; http://php.net/smtp-port smtp_port = 25 ; For Win32 only. ; http://php.net/sendmail-from sendmail_from = my@emailaddress.com 

Step 4: Add C:\php to the PATH environment variable

To ensure Windows can find the PHP executable, you must add it to the PATH environment variable. Click the Windows Start button and type “environment”, then click Edit the system environment variables. Select the Advanced tab, and click the Environment Variables button.

Scroll down the System variables list and click Path, followed by the Edit button. Click New and add C:\php .

Note that older editions of Windows provide a single text box with paths separated by semi-colons ( ; ).

Now OK your way out. You shouldn’t need to reboot, but you may need to close and restart any cmd terminals you have open.

Step 5: Configure PHP as an Apache module

Ensure Apache is not running and open its C:\Apache24\conf\httpd.conf configuration file in a text editor. Add the following lines to the bottom of the file to set PHP as an Apache module (change the file locations if necessary but use forward slashes rather than Windows backslashes):

# PHP8 module PHPIniDir "C:/php" LoadModule php_module "C:/php/php8apache2_4.dll" AddType application/x-httpd-php .php 

Optionally, change the DirectoryIndex setting to use index.php as the default in preference to index.html . The initial setting is:

 DirectoryIndex index.php index.html 

Save httpd.conf and test the updates from a cmd command line:

Syntax OK will appear … unless you have errors in your configuration.

If all went well, start Apache with httpd .

Step 6: Test a PHP file

Create a new file named index.php in Apache’s web page root folder at C:\Apache24\htdocs . Add the following PHP code:

Open a web browser and enter your server address: http://localhost/. A PHP version page should appear, showing all PHP and Apache configuration settings.

You can now create PHP sites and applications in any subfolder of C:\Apache24\htdocs . If you need to work more than one project, consider defining Apache Virtual Hosts so you can run separate codebases on different localhost subdomains or ports.

How to install and configure PHP

PHP is a general-purpose scripting language well-suited for Web development since PHP scripts can be embedded into HTML. This guide explains how to install and configure PHP in an Ubuntu System with Apache2 and MySQL.

Prerequisites

Before installing PHP you should install Apache (or a preferred web server) and a database service such as MySQL.

• To install the Apache package, please refer to our Apache guide.
• To install and configure a MySQL database service, refer to our MySQL guide.

Install PHP

PHP is available on Ubuntu Linux, but unlike Python (which comes pre-installed), must be manually installed.

To install PHP – and the Apache PHP module – you can enter the following command into a terminal prompt:

sudo apt install php libapache2-mod-php 

Install optional packages

The following packages are optional, and can be installed if you need them for your setup.

PHP-CLI
You can run PHP scripts via the Command Line Interface (CLI). To do this, you must first install the php-cli package. You can install it by running the following command:

sudo apt install php-mysql 

sudo apt install php-pgsql 

Configure PHP

If you have installed the libapache2-mod-php or php-cgi packages, you can run PHP scripts from your web browser. If you have installed the php-cli package, you can run PHP scripts at a terminal prompt.

By default, when libapache2-mod-php is installed, the Apache2 web server is configured to run PHP scripts using this module. First, verify if the files /etc/apache2/mods-enabled/php8.*.conf and /etc/apache2/mods-enabled/php8.*.load exist. If they do not exist, you can enable the module using the a2enmod command.

Once you have installed the PHP-related packages and enabled the Apache PHP module, you should restart the Apache2 web server to run PHP scripts, by running the following command:

sudo systemctl restart apache2.service 

Test your setup

To verify your installation, you can run the following PHP phpinfo script:

You can save the content in a file – phpinfo.php for example – and place it under the DocumentRoot directory of the Apache2 web server. Pointing your browser to http://hostname/phpinfo.php will display the values of various PHP configuration parameters.
