Bug #61220 [Com]: is_numeric returns FALSE for chr(0) and CHR(1) that are BIT, so NUMERIC.

Edit report at https://bugs.php.net/bug.php?id=61220&edit=1 ID: 61220 Comment by: dosergio at ig dot com dot br Reported by: dosergio at ig dot com dot br Summary: is_numeric returns FALSE for chr(0) and CHR(1) that are BIT, so NUMERIC. Status: Open Type: Bug Package: *General Issues Operating System: ALL PHP Version: Irrelevant Block user comment: N Private report: N New Comment: I also tested chr(0) and chr(1) with is_boolean and of course the function says it is not. I think is_numeric and is_boolean should be revised to include 0, 1, chr(0) and chr(1) as valid numeric and valid booleans.

Would php adopt it ? I had to use a strange conditional because of this supposed "bug": [code] if( is_numeric($myvar) || ord($myvar) < 2) { # to check char 0 or 1 that are BITS, binary numeric. } [/code] Test script: --------------- if( is_numeric( chr(0)) || is_numeric(chr(1)) ) echo "is_numeric is great!"; else echo "is_numeric might be a little buggy"; Expected result: ---------------- is_numeric shoud recognize chr(0) and chr(1) as numeric, as they are chars for bit information. Actual result: -------------- is_numeric says chr(0) and chr(1) are both NOT numeric. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61220&edit=1
