Bug description: define() allows non variable-like strings (spaces, slashes)
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)
