PHP 7.0 on CentOS/RHEL 6.9 and 7.4 via Yum
PHP 7.0.23 has been released on PHP.net on 31st August 2017, and is also available for CentOS/RHEL 6.9 and 7.4 at Webtatic via Yum.
PEAR installer now supports PHP 7.0, however most pecl libraries will not support it as well without their maintainers adding compatibility, so only pecl libraries that do support it will be in the Webtatic repository.
- pecl memcache extension – no sign of PHP 7 support development in official source repository
Update 2016-12-17 – Webtatic now has released PHP 7.1.0 for CentOS/RHEL 6 and 7
PHP 7.0.0 comes with new version of the Zend Engine with features such as (incomplete list):
- Improved performance: PHP 7 is up to twice as fast as PHP 5.6
- Consistent 64-bit support
- Many fatal errors are now Exceptions
- Removal of old and unsupported SAPIs and extensions
- The null coalescing operator (??)
- Combined comparison Operator (<=>)
- Return Type Declarations
- Scalar Type Declarations
- Anonymous Classes
To see what else has been added, check out the Migrating from PHP 5.6.x to PHP 7.0.x.
To install, first you must add the Webtatic EL yum repository information corresponding to your CentOS/RHEL version to yum:
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm
Now you can install PHP 7.0’s mod_php SAPI (along with an opcode cache) by doing:
yum install php70w php70w-opcache
You can alternatively install PHP 7.0’s php-fpm SAPI (along with an opcode cache by doing:
yum install php70w-fpm php70w-opcache
See the package list below for additional SAPIs and PHP extensions.
If you would like to upgrade php to this version it is recommended that you first check that your system will support the upgrade, e.g. making sure any CPanel-like software can run after the upgrade.
Unless you know what you are doing, it is risky upgrading an existing system. It’s much safer to do this by provisioning a separate server to perform the upgrade as a fresh install instead.
If you know what you are doing, you can upgrade PHP by:
yum install yum-plugin-replace yum replace php-common --replace-with=php70w-common
It will likely give you a message “WARNING: Unable to resolve all providers …“. This is normal, and you can continue by tying “y”. You will be given a chance to see what packages will be installed and removed before again being given a chance to confirm.
