Hi Pierre,
After checking places where is_numeric... functions are used
(http://lxr.php.net/ident?i=is_numeric_string), it looks like changing to
allow *trailing* spaces would have an impact in zend_operators.c for at
least compare_function() (and I guess increment_function() too). e.g. ('1'
== '
Guys,
I can't keep following endless (and large) email threads about things
like that. Could you please work together on a more formal proposal
taking into consideration existing state, BC, any potential future
issues etc? If you need some guidelines, I quite like how Pythong PEPs
do it [

And yet, the way Matt W was talking at one point, it seemed he wanted
to change that as well...
Or perhaps I misunderstood.

If you break that, you're in big trouble to a lot of scripts all over
the planet, which rely on the leading space to trap their

Hi Jochem,
Leading whitespace is already allowed with PHP's is_numeric() function (and
corresponding internal one), math operations, etc. Only when it precedes
.123 or -.123 does the behavior change. :-)

Hi Andrei,
You seem to be the array-function-person ;-) so I'll ask you if the
array_count_values() result in my previous message is what's intended?
Seems to me leading whitespace should *not* be ignored. I didn't try it
yet, but it seems zend_[u_]symtable_[find|update] should simply be used,

Hello again,
I discovered a couple more things is_numeric... is causing problems with
(leading whitespace). I doubt any of the examples I've given make sense to
regular users who don't know what's happening behind the scenes. Add these
to the "wrong" list:
is_numeric(' .123') // bool(false)
' .
Hi all,
Since I've been looking at is_numeric_[string|unicode], I found a weird
thing it causes; probably doesn't make sense to users; bug? Look:
abs(-1e500) // float(INF)
abs('-1e500') // int(1) WRONG
abs('-1e100') // float(1.0E+100)
is_finite(1e500) // bool(false)
is_finite('1e500') // bool(t
17 matches
