Description:
------------
I think that is_numeric should return TRUE if you pass chr(0) or chr(1) to it because this chars are
stored in database as BITs, that are numeric in the binary context. 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.
