Upgrade to PHP 7 on CentOS

Well, PHP7 has just been released as you can read on the php.net website. Time to celebrate 🙂 So in this quick tutorial, I will note necessary steps to ugprade to PHP 7 on CentOS, assuming that you are using PHP with FPM with remi repo. Necessary steps are as follows:

1. First, install yum-utils:

   yum install -y yum-utils

2. Enable php70:

   yum-config-manager --enable remi-php70

3. If you are using php-mysql and php-opcache with PHP5-4. these extensions will not be compatible with PHP7. So you will need to remove them:

   yum remove php-opcache php-mysql

4. Upgrade to PHP7:

   yum update php\*

5. Install php-mysqli to replace php-mysql extension, and install new opcache one:

   yum install php-mysqli
   yum install php-opcache

   Another way to upgrade php-myql seamlessly:

   yum shell
   remove php-mysql
   install php-mysqlnd
   run
   quit

6. All done! Enjoy new PHP version
