Hello,

following problem with 4.3.2RC3 (it works with 4.3.1)

Browser URL :
http://intraddms/fiatbearb/adr_index.php?1234567890

var_dump from $_REQUEST

array(2) { [0]=>  string(1) "0" ["PHPSESSID"]=>  string(32)
"3f8ee06297a919da9d84cd713473fe5d" }

if have a query like

if(!isset($_REQUEST["1234567890"]){ << BUG? it's alway true
 initialize some variables
}

if i replace it with $_GET it works. Switch back to 4.3.1 it works also with $_REQUEST

regards
Ingo Thierack

This was broken by another fix related to $_REQUEST.
Assigned to Ilia who broke it. :)

The problem appears only with numeric argument names:

test.php?123=45   =>

_REQUEST: Array
(
    [0] => 45
)
_GET: Array
(
    [123] => 45
)

test.php?a123=45   =>

_REQUEST: Array
(
    [a123] => 45
)
_GET: Array
(
    [a123] => 45
)

This may very well be a "Won't Fix" but we will see what Ilia thinks.

This has traditionally not worked very reliably.  PHP has always expected to see valid variable names in the get and post key/value pairs.  For example, try putting a . (dot) in a variable name.  You will see it gets converted to an underscore.  The idea here is that anything in $_GET/$_POST/$_COOKIE can be extract()'ed directly into the symbol table and you can't have variables called $123 and $.abc so these variable names are technically not supported in our GPC arrays.  That doesn't mean you can't use them, you will just have to do a bit of work yourself.  In your case you would need to look at $QUERY_STRING and parse that.

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

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