Recently I needed to migrate legacy PHP application from PHP 5.2 to at least PHP 5.6.

This functionality has been deprecated as of PHP 5.3.0 and removed as of PHP 5.4.0. I will demonstrate how to emulate register_globals directive and session_register()/session_unregister() functions in PHP 5.6 or later.

Back in February, 2017 I wrote about unofficial row grouping plug-in for jQuery DataTables, see jQuery DataTables: Row grouping and checkboxes.
However there is also official extension for row grouping – RowGroup. It works differently than unofficial plug-in and adds a separate parent row for a group of child rows.
