Hello
(I guess pre tags are broken, but will use them anyway incase they get fixed.)
The most important useage of veriable veriable that I have found is not even mentioned here.
That is, function veriables:
$funcvar="my_formdatafunc";
$$funcvar(); // calls the function w/no parameters.
${$funcvar( $var1, "string", $nutervar)}; // w/parameters
I've been using this undocumented feature for some time and only just now realized that it is
undocumented.
It is most usefull with form data processing to handle multiple forms with one script and such.
Where $funcvar my be the name of a database table used as a function name.
