This is most likely a stupid question, but I didn’t find an answer in the docs.
(And if it’s a stupid question it should be easy to get an answer
In php and template code I frequently find the tilde character (~), often in conjunction with "[", for instance [tt]"[~$id~]"[/tt] being magically transformed to index.php?id=##. Or used in a template like [tt]a href="[~[(site_start)]~]"[/tt]
Can someone explain me how that works??
Thanks in advance.
