Sugar and older versions of PHP
The latest version of PHP that Sugar 6.5 supported was PHP 5.3 which was released back in 2009. That is a long time ago folks. A sizable portion of the Sugar Developer community was in grade school back when PHP 5.3 was cool.
While we like to keep Sugar on the cutting edge, we have not been able to keep up to date with the latest PHP release. We have needed to maintain an upgrade path in each new Sugar release for customers still on Sugar 6.5. That is, up until now.
PHP Support matrix
As of Sugar 7.7.1 release:
|Sugar version||Supported PHP versions|
We do not plan on supporting 4 different versions of PHP forever, so you can expect to see support for older versions of PHP, such as PHP 5.3, to be dropped in upcoming Sugar releases.
For the complete and up-to-date reference of supported PHP versions, please view our Supported Platforms documentation.
