If you use the $func_name() syntaxt and the function's parameter is
defined as pass-by-reference, this should work fine.
function func(&$a) {
$a = 1;
}
$a = 0;
$funcName = 'func';
echo '$a before: '.$a.'<br/>';
$funcName($a);
echo '$a after: '.$a.'<br/>';
This doesn't solve the problem if the "dynamic" function also has a
"dynamic" number of parameters, but this should solve at least one
simple problem.
