System requirements

Generally all SetaPDF 2 components will run on any PHP version above 5.2.17 until revision 817. Future releases will require PHP 5.4 as the minimum PHP version.

Due to security reason or missing feature support in outdated PHP versions some features may be limited in specific components already before or in revision 817. In that case please refer to the system requirements section of the specific component.

An up to date PHP version (> 5.6 or 7) is recommend for best performance and memory results.

Following PHP extensions must be enabled in the PHP configuration:

Because PDF parsing and writing is a performance intensive task the components should be used on a machine with a fast CPU. Also the max_execution_time value should be taken into account.

Same for memory usage. Because PDF documents are sometimes build with several thousands of individual objects, the components will need memory for managing these things. Maybe it is needed to touch the memory_limit value as well.
