New Comment:
btw, it may imply corresponding bugs in 'constant()' and 'defined()'.
imho, they would be better left untouched so it's easier to use them as
they currently work. if they are fixed, they should produce
E_WARNING/NOTICEs (worst case) so they can be suppressed with '@' when
checking. this is especially true of constant().

Description:
------------
define()ing a constant with spaces, / signs, etc. doesn't throw an
error (or warning).
i happened to try to create a constant with the name
'U/L DIR' and it worked. that's two illegal chars. since constant names
like "2FOO" are checked and not allowed, shouldn't these also not be
allowed?
sure doesn't satisfy "The name of a constant follows the same rules as
any label in PHP." or the regexp
[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*
a name like that obviously can't be used (tried quotes and braces) but
it works just fine with 'defined()', 'constant()' and shows up in
get_defined_constants().
Reproduce code:
---------------
define('U/L DIR', 'myuploaddir');
if (defined('U/L DIR')) { //true
echo 'yup';
echo constant('U/L DIR');
print_r(get_defined_constants());
}
// all the lines above print 'myuploaddir' for 'U/L DIR'
Expected result:
----------------
E_ERROR since it's violates label rules (an E_WARNING at the least?)
Actual result:
--------------
spaces, etc. work just fine. (it shouldn't)
