doubleval doubleval -- Alias of floatval() <http://www.php.net/manual/en/function.floatval.php> Description This function is an alias of floatval() <http://www.php.net/manual/en/function.floatval.php>. Note: This alias is a left-over from a function-renaming. In older versions of PHP you'll need to use this alias of the floatval() <http://www.php.net/manual/en/function.floatval.php> function, because floatval() <http://www.php.net/manual/en/function.floatval.php> wasn't yet available in that version.

No, it's floatval. Doubleval is an alias left over from hwen floats were called doubles... Scott Fletcher wrote:

I do know that integer, string, double, float, etc.... are different..
       
I
have been using hte appropriate method like in javascript and c
       
programming,
     
like converting it to integer and so on.... But when I start using PHP,
       
I
find no such document of it and I have been using it for 3 years without
       
a
problem. I asked people is there such a thing as converting it by using
       
the
     
function and they told me there is no such a thing and that it is done automatically... Now my time is a little bit wasted. So, I will
       
correct
the problem with the php script... I recently looked up on the manual as Jason Wong instructed me to. I havne't found the answer since the document is a little bit mixed up. Okay, I'm going back to my old way as I did in javascript and c
       
programming.
     
So for php, it would be floatval() for float... strval() for string.... settype() for whatever...... intval() for integer.... Um, what about double??? Thanks, Scott F. "Chris Hayes" <chayes@antenna.nl> wrote in message news:5.1.1.6.0.20030127211703.014c47f8@pop4.antenna.nl...

uh oh...
         
I don't see why a string wouldn't work when I use "08" (string) and
           
match
     
it
       
against the integer 8, or 08.
           
They're just different types. Normally PHP is veeery flexible with types, like javascript, but it just can't be flexible for you here
         
because
       
it needs to choose the most logic to the entire pool of programmers,
         
and
         
then
       
"08" = a string 8 = a decimal integer 08 = by definition an impossible octal integer, so 0. Since you cannot tell PHP that $var is of a certain type like in
         
[other]
programming languages, for example you want it to be treated as an
         
integer,
       
PHP will handle it as what seems to be the most logic. You can try to use intval (does not alter a variable, only the value as
         
it
     
is used in a calculation or an if() statement) or settype (alters the variable).

-----Original Message----- From: Scott Fletcher [mailto:scott@abcoa.com] Found a PHP bug, I'm using PHP version 4.2.3. I have been struggling with why PHP code failed to work with the month is August or September
               
I stumbled into this one a short while ago myself. It is not a bug,
             
but a
       
feature! ;) When passing values of 08 or 09 (Aug and Sep), PHP
             
interprets
       
them as octal numbers (because of the leading 0). However, 08 and 09
             
are
       
invalid octal numbers, so PHP converts them to zero. The fixes are numerous: - remove the leading zero; - add zero to them before passing (addition forces a type
             
conversion
     
to
       
int); - force a type conversion to integer using (int); - quote them (when PHP converts a string to an integer, it removes
             
the
       
leading zero); Kirk
