In some pages my POST variables make it to the next page missing the first 4 character's. If I send "test_data", I'll get only "_data" on the other side. The funny thing is that it only happens in one machine. I have two other machines with the same configuration and nothing wrong happens. And it appears that this bug happens only with array from form variables. Any thoughts??? ------------------------------------------------------------------------ [2002-11-29 14:20:38] jazar at zacks dot com The answer will be "We are not support previous PHP versions" ;-) ------------------------------------------------------------------------ [2002-11-28 14:00:39] sk at pilonet dot de My problem might be affected by this bug. I'm using PHP 4.2.3 (sapi) on Windows 2000 Server running Apache 1.3.27 as Webserver. My form: <form action="/test.php" name="test" method="post"> <input type="text" name="start" size="20" maxlength="20" value="100"> <input type="submit" name="submit" value="Speichern"> </form> Then I'm dumping $_POST, where the following happens: When input was an integer from 1-999 it is displayed correctly. From 1000 on the corresponding post value is "false". Inserting "abcdefgh" in the form results in "efgh"... Any Ideas? Copying that example to my debian system, running PHP 4.2.3 on an apache 1.3.26, the result is fine and works as expected. Hope that helps finding another bug, Stefan ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
