php 5.3 compatibility

[chilek]

Really doesn't it work with PHP 5.3?
If it doesn't, would it be difficult to adjust it to 5.3?
Many enterprise linux distributions still use PHP 5.3.

The 5.3 version of PHP is unsupported, its end of life was more than 2 yeas ago (14 August 2014)!
If you are running PHP 5.3 in production I strongly recommend to upgrade to a recent version.

@nicolaasuni I know that but RHEL/CentOS 6.x still use PHP 5.3 series maintained by their own!
