That's what I was asking. I just am rather careful there because somebody
wrote that code so he should have meant something by it - maybe there are
reasons I'm not aware of.
well as discussed before this code is an relict from register_globals=on
With regard to php-lang, are there any opinions on whether
a construct like this should be legal?
'${' expression '}'
where expression evaluates to an arbitrary string, not
necessarily to an identifier (which is basically
[a-z][a-z0-9]*).
why not? you can even use ä,ü,ö without using ${' äöü '}, should these be legal - let the user decide how to write his code
I'm not sure if I already said, using variables varialbles this might be helpful
$a=array('foobar 1','foobar 2','foobar 3','foobar1',' foobar 1');
foreach($a AS $val) {
$$val=somestuff(); }
this is fairly legal right now and of course this should be legal to be able to access them manually
echo ${'foobar 1'};
if wisely used an interesting feature
