PHP 7 on Ubuntu

It has been quite some time since PHP 7 was released, it has major bug fixes, improved and new ways of writing syntax and many other changes you can find here.

So I decided to write a guide on how to upgrade or install and setup PHP 7.x.x on your Ubuntu based system.

This is a major update, this can break your website or web application, please test your website or web application in a development environment before applying this to your production environment.

Installing

Adding PHP 7 ppa to the local database.

sudo add-apt-repository ppa:ondrej/php-7.0  

Updating the local database.

sudo apt-get update  

Installing PHP 7.

sudo apt-get install php7.0 php7.0-cli php7.0-common php7.0-curl php7.0-fpm php7.0-gd php7.0-json php7.0-mcrypt php7.0-mysql php7.0-opcache php7.0-sqlite3  

Now you can run PHP -v in the terminal to check if it has been installed successfully.

Upgrading from PHP 5 to PHP 7.

This will purge PHP 5 and remove unwanted dependencies and then clean up the temporary files

<code class="bash">sudo apt-get purge php5* && sudo apt-get --purge autoremove && apt-get clean && sudo apt-get install php7.0 php7.0-cli php7.0-common php7.0-curl php7.0-fpm php7.0-gd php7.0-json php7.0-mcrypt php7.0-mysql php7.0-opcache php7.0-sqlite3  

Switching NGINX to PHP 7 from PHP 5

Edit the NGINX config to work with PHP 7 FPM, go the specific server config and change the following lines.

From this

location ~ .php$ {  
            try_files $uri =404;
            fastcgi_split_path_info ^(.+.php)(/.+)$;
            fastcgi_pass unix:/var/run/php5-fpm.sock;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include        fastcgi_params;
        }

To this

location ~ .php$ {  
        try_files $uri =404;
        fastcgi_split_path_info ^(.+.php)(/.+)$;
        fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }

The only line changed is the fastcgi_pass.

From this

fastcgi_pass unix:/var/run/php5-fpm.sock;  

To this

fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;  

Now all the PHP config files are moved to /etc/php/7.x from /etc/php5/.

So the path to the php.ini is now located in /etc/php/7.x/fpm/php.ini, this means any edits done to the older PHP 5 php.ini need to be re-applied because this is a fresh new in file.

You can restart PHP 7 FPM by entering this command.

sudo service php7.0-fpm restart
