php51s does not exists

[Spacedust]

So it's not possible to use it as secondary PHP.

[MRatWork]

Only for CentOS 5 (but possible php 5.1-5.4). CentOS 6 possible php 52-56.

php56s does not exist so only possible as main PHP.

[MRatWork]

No phpXYs except php52s, php53s and php54s.

Multiple php (via 'php-fpm' and 'secondary php') using phpXYm. PhpXYs (read 's' as special) is special for panel.

Waiting for updates to:

php54-5.4.39-1.ius.el6 - php 5.4.40
php55u-5.5.23-1.ius.el6 - php 5.5.24
php56u-5.6.7-1.ius.el6 - php 5.6.8

See http://xl2.mratwork.com/ (using CentOS 5). Still something with php51 for 'additional .ini files parsed'.
