#25612 [Opn->Bgs]: ip2long() and long2ip() results differs.

ID: 25612 Updated by: iliaa@php.net Reported By: marrtins at hackers dot lv -Status: Open +Status: Bogus Bug Type: *Network Functions Operating System: Linux 2.4.20 PHP Version: 4.3.1 New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php Like wez said, prefixing the IP portion with a 0 makes PHP think the number is in octal and not decimal form. This is not unique to PHP, "ping 62.234.229.040" will try to ping 62.234.229.32. Previous Comments: ------------------------------------------------------------------------ [2003-09-20 07:00:19] wez@php.net 040 is octal for 32. ------------------------------------------------------------------------ [2003-09-20 02:30:41] marrtins at hackers dot lv Description: ------------ Should ip address '62.234.229.040' differ from '62.234.229.40' ? I think not. Please check it out! Reproduce code: --------------- <?php printf("%u\n", ip2long('62.234.229.040')); // 1055581472 print long2ip('1055581472')."\n"; // 62.234.229.32 printf("%u\n", ip2long('62.234.229.40')); // 1055581480 ?> Expected result: ---------------- 1055581480 62.234.229.32 1055581480 Actual result: -------------- 1055581472 62.234.229.32 1055581480 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25612&edit=1
