Derick ------------------------------------------------------------------------ [2001-08-08 19:02:22] jeroen@php.net So you say that var_dump(5000000000) -> int(2147483647) And not, as expected: float(5000000000) PHP uses some system routines for that, this isn't coded in PHP. Zend/zend_language_scanner.l:line_1000: (...) errno = 0; /*long*/ lval = strtol(the_digit_as_a_string, NULL, 0); if (errno == ERANGE) { /* overflow */ (...) If strtol is doing his job right, there is no bug here... Are you sure this didn't happen with the older PHP-version, on the same box? Or is it just another pentium-bug (j/k) It would help if you try to execute these lines in C, and see wether ERANGE is set correctly. If it is, I'm lost. By the way, please try also some other values than 5 billion, some really huge values, and also some really negative values. Please use var_dump on them. ------------------------------------------------------------------------ [2001-07-19 01:59:05] cynic@php.net at your service ------------------------------------------------------------------------ [2001-07-19 00:23:14] matysekj@usms.org Absolutely. I've written just one test script with just those 2 lines in it. I copied this same file to 3 servers now - the 2 that I've already mentioned plus another FreeBSD server (identical in hardware and OS config to the other) running 4.03PL1. The only one of these servers that prints out 2147483647 is the FreeBSD server running 4.06 (also did it with 4.05). The other 2 servers print out 5000000000. I also remember another location in my site that was affected by this bug, and I can GUARANTEE that it did not occur on the affected server until I updated it to 4.05. Please change the status of this bug report back to open. ------------------------------------------------------------------------ [2001-07-19 00:15:34] cynic@php.net are you sure you don't initialize the variable with 5 Million on the Linux box? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
