In today's development environments, **PHP** is a widely-used server-side scripting language and an essential tool for building dynamic websites and applications. Although newer versions of PHP are frequently released, **PHP5.5** still holds an important place in some projects. This article provides a comprehensive **PHP5.5 installation guide on Linux**, helping you quickly set up a development environment.
Before you start the installation, make sure your Linux system is updated to the latest version. You can update the system using the following commands:
sudo apt-get update
sudo apt-get upgrade
Additionally, you need to install some required development tools and dependencies. Use the following command to install these tools:
sudo apt-get install build-essential libxml2-dev
Next, you need to download the **PHP5.5** source code package from the official website. You can use the following command to download it:
wget http://museum.php.net/php5/php-5.5.38.tar.gz
After the download is complete, extract the downloaded file:
tar -xzvf php-5.5.38.tar.gz
Enter the extracted directory and start compiling PHP5.5 with the following commands:
cd php-5.5.38/
./configure --enable-mbstring --with-mysql --with-zlib --enable-soap
make
sudo make install
After installation, you need to configure the PHP settings. The **php.ini** file is usually located in the PHP folder within the installation directory. You can copy the php.ini file with the following command:
cp php.ini-development /usr/local/lib/php.ini
Use a text editor to open and edit the **php.ini** file, and adjust the settings as needed:
nano /usr/local/lib/php.ini
To test if your installation was successful, you can start the PHP built-in server. Use the following command:
php -S localhost:8000
Open your browser and go to http://localhost:8000. You should see the PHP info page, indicating that **PHP5.5** has been successfully installed and is running.
By following these steps, you have successfully installed **PHP5.5** on your Linux system. While this version has been around for a while, it is still an important choice for some legacy projects and systems. We hope this **PHP5.5 installation guide on Linux** helps you with a smooth setup and keeps you on the right track in your development journey.
