Reproduced PHP 5.6 on Centos/rhel 7.0 and 6.6 via Yum

https://webtatic.com/packages/php56/

PHP 5.6.5 have been released on Php.net on 22nd January, and are also available for Centos/rhel 6.5 at webtatic via Yum .

PHP 5.6 Adds new features such as:

• Constant scalar expressions
• Variadic functions
• Argument unpacking
• Exponentiation operator
• Support for large (>2GIB) file uploads
• SSL/TLS improvements including peer verification by default
• A new command line debugger called phpdbg

To see what else have been added, check out the "What's with changed in PHP 5.6.x.

To install, first you must add the Webtatic EL yum repository information corresponding to your Centos/rhel version to Yum :

Centos/rhel 7.x:

RPM-UVH HTTPS://MIRROR.WEBTATIC.COM/YUM/EL7/EPEL-RELEASE.RPMRPM-UVH https://mirror.webtatic.com/yum/el7/ webtatic-release.rpm

Centos/rhel 6.x:

RPM-UVH https://mirror.webtatic.com/yum/el6/latest.rpm

Now the can install PHP 5.6 (along with a opcode cache) by doing:

Yum Install php56w Php56w-opcache

If you would like to upgrade PHP to this version it's recommended so you first check that your system would support the upgrade, e.g. making sure any Cpanel-like software can run after the upgrade.

Unless you know doing, it's risky upgrading an existing system. It's much safer to does this by provisioning a separate server to perform the upgrade as a fresh install instead.

If you know what is doing, you can upgrade PHP by:

Yum install yum-plugin-replace yum replace--enablerepo=webtatic-testing Php-common--replace-with=php56w-common

It'll likely give you a message "warning:unable-Resolve all providers ...". This is normal, and you can continue by tying "Y". You'll be given a chance to see what packages'll be installed and removed before again being given a chance to confirm .

Sapis–different Runtime environments of PHP

mod_php NTS

(non-thread safety) Contained in the php56w package, this SAPI integrates into Apache Httpd 2.2.*. It is the standard SAPI for use with httpd prefork MPM (the default mode httpd is ran under. It is not a thread-safe, but doesn ' t need to being due to prefork using threads. It ' s located at/usr/lib[64]/httpd/modules/libphp5.so

Cli

Contained in the PHP56W-CLI package, this SAPI allows running scripts from the command-line, and also have a built-in Web server for Development-use. Located at/usr/bin/php

Fpm

Contained in the PHP56W-FPM package, FPM (FastCGI process Manager) is a scalable FastCGI Process, which acts similar To how HTTPD Prefork MPM Works managing it ' s forks. Located AT/USR/SBIN/PHP-FPM, it is controlled using THE/ETC/INIT.D/PHP-FPM service script

phpdbg

Contained in the php56w-phpdbg package, phpdbg have the ability to debug scripts using breakpoints from the Command-l INE, and also supports remote-debugging using a external Java client for remote communication.

Embedded

mod_php TS

(thread safety) Contained in the php56w package, this SAPI integrates into Apache Httpd 2.2.*. It is the standard SAPI for use with httpd worker mpm. It's supposed to being thread-safe, but can ' t guarantee-to IS, and certainly not under additional PHP extensions. It ' s better to use FastCGI sapis than this one. It ' s located at/usr/lib[64]/httpd/modules/libphp5-zts.so

Opcode Caches

The PHP distribution now comes with an opcode cache. The Zend optimizer+ opcode cache, now known as the Zend opcache extension. This extension are optional, so does not preclude you from using a alternate one.

Due to it being included in the PHP source distribution, it'll be a well maintained and more suitable Opcode Cache ' s is being updated over the coming months.

Yum Install Php56w-opcache

Error_reporting E_all now includes e_strict

As mentioned in the PHP 5.4 guide:

You could get a lot more errors coming out of your error logs if by default your error_reporting are set to E_all now without Explicitly turning off e_strict. The default php.ini that comes with the PHP package turns this off by default, but if your is upgrading from an existing I Nstallation, your php.ini May is updated, meaning this would likely be turned on.
