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

    Do I understand you correctly that your explanation is
    "because we can"?

Sascha, Again, *YES*, unless it's a blunt bug, then 'because we can' is exactly the right reasoning. Why is it legal to write a for loop in PHP? I'll tell you why, because if you do it, it'll work. That's no different.

Regardless, the above construct seems to be valid since PHP

    3, so it will be part of the specification.

Do you realize that your explanation is identical to that of Andre? :) Zeev -- Zeev Suraski <zeev@zend.com> CTO, Zend Technologies Ltd. http://www.zend.com/
