Request #56810 input_get octal and hexa
Submitted: 2006-01-31 10:08 UTC Modified: 2006-01-31 14:13 UTC

Description:
------------
Hello,
i don't understand filter on octal and hexa. Why input_get return one error on '-01' or '-0xF' in $_GET|POST ?

Here: http://www.php.net/manual/en/language.types.integer.php
decimal     : [1-9][0-9]*
            | 0

hexadecimal : 0[xX][0-9a-fA-F]+

octal       : 0[0-7]+

integer     : [+-]?decimal
            | [+-]?hexadecimal
            | [+-]?octal

With octal value, it's not possible to send '00', why ?

logical_filters.c
/* state 0 */
if (*p == '-' || *p == '+') {
  ctx_multiply = *p == '-' ? -1 : 1; p++; goto stateI1; <<<=== Why not continue to Octal or Hexa goto ?
} else {
  goto stateOH1;
}

Thank you for your work.


Expected result:
----------------
I expect negatives values for negatives input.
I expect a value equal at 0 for octal value 00.

Actual result:
--------------
$source = INPUT_GET;
$name = 'foo';

$ret = input_get($source, $name, array('flags' => Filter::FILTER_FLAG_ALLOW_OCTAL));

echo '$ret = '; echo $ret;

This bug has been fixed in CVS.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.

This was not supposed to work, and therefore I reclassified it as Feature Request. I committed a change to CVS that implemented this FR.
