Query String? What does ::valuename:: represent?

[kellypw]

This is probably a silly question and something I should know, but... I inherited an application that uses the following in constructing a link - I've been working backward to try and figure out how the entire thing works:

href='edit_dir.php?action=".ACTION_CHANGE."&ret=show_projects&id=::item_id::'>

I'm not quite sure what/how the 'id = ::item_id::' is getting used/generated? What does the item embedded in the double colons represent? Something to do with the DOM?

TIA-

it's probably an add on that they were parsing by

add $parse=preg_split("/::*.::/",$input);

to your script to parse by $parse will be an array when done.
