Installation in Ubuntu: PHP 7.0.0

 

To install PHP 7.0.0 on an Ubuntu system, follow the steps below. Please note that PHP 7.0 is an older version, and support for it has ended, so it is generally recommended to use a more recent version of PHP if possible. However, if you specifically need PHP 7.0.0 for compatibility reasons, here's how you can install it:

Step 1: Add the PHP Repository (if needed)

PHP 7.0 is not available in the default Ubuntu repositories for newer versions of Ubuntu. You can use the Ondřej Surý's PPA repository, which provides PHP packages for older versions.

1. First, update your package list and install the necessary software to add the PPA repository:

   sudo apt update
   sudo apt install software-properties-common
   

2. Add the repository:

   sudo add-apt-repository ppa:ondrej/php
   

3. Update the package list again:

   sudo apt update
   

Step 2: Install PHP 7.0

Now that the repository has been added, you can install PHP 7.0.0 and related packages.

1. Install PHP 7.0:

   sudo apt install php7.0
   

2. To install additional PHP 7.0 packages (like PHP-FPM, PHP-CLI, or other commonly used PHP extensions), you can do so with the following commands:

   sudo apt install php7.0-cli        # Command line interface
   sudo apt install php7.0-fpm        # PHP-FPM (FastCGI Process Manager)
   sudo apt install php7.0-mysql      # MySQL support
   sudo apt install php7.0-xml        # XML support
   sudo apt install php7.0-curl       # cURL support
   sudo apt install php7.0-mbstring   # Multibyte string support
   sudo apt install php7.0-zip        # ZIP support
   

   You can install other extensions depending on your project’s needs.

Step 3: Verify the Installation

To check if PHP 7.0 is installed successfully, you can run:

php -v

You should see an output similar to this:

PHP 7.0.0 (cli) (built: ...)

This confirms that PHP 7.0.0 is successfully installed.

Step 4: Set PHP 7.0 as the Default (if multiple PHP versions are installed)

If you have multiple PHP versions installed, you can set PHP 7.0 as the default by running:

sudo update-alternatives --set php /usr/bin/php7.0
sudo update-alternatives --set phpize /usr/bin/phpize7.0
sudo update-alternatives --set php-config /usr/bin/php-config7.0

Step 5: Restart Your Web Server (if needed)

If you're using PHP with Apache or Nginx, make sure to restart your web server for the changes to take effect:

For Apache:

sudo systemctl restart apache2

For Nginx (if you're using PHP-FPM):

sudo systemctl restart php7.0-fpm
sudo systemctl restart nginx

Conclusion

PHP 7.0 should now be installed on your system. Keep in mind that PHP 7.0 has reached its end of life and no longer receives security updates, so consider upgrading to a more recent version if possible.
