Hi Carl, Some thoughts on PHP 5.6 on EL5:
* PHP 5.6 introduces secure defaults for SSL/TLS connections from PHP (such as high strength ciphers including ECDHE based ones, TLS preference). RHEL/CentOS 5 have an old openssl package 0.9.8e, which doesn’t have support for these ciphers and TLS 1.1+ as well as no SNI support, so doesn’t provide the level of capabilities most PHP 5.6 installations would benefit from. The defaults also severely limit the number of secure TLS 1.0 ciphers to I think just 3DES, which adds more cpu load. Of course you could build it against a later openssl package if you were to add parallel package support, but then would need to maintain openssl. The same isn’t an issue for RHEL/CentOS 6. * Though RHEL/CentOS 5 will effectively be EOL March 2017, RHEL offers Extended Upgrade Support subscriptions, offering support for servers 3 years beyond that. Whilst using this, RHEL servers would continue to get support for base packages, the IUS EL5 repository would effectively EOL php56u on that platform version before php56u becomes EOL, leaving EUS supported servers unable to update even when php.net is still releasing updates. I doubt EUS subscriptions are used much by servers using IUS though.
