Hi List,
I'm having a problem with the behavior of the floor() function:
echo floor(327.03 * 100)."\n"; //prints "32702" and not "32703"!!
Sanity check:
var_dump(327.03 * 100); //prints "float(32703)" as expected
Any ideas why this happens, and how to work around it?
Thanks,
Mattias

Read the floating point precision part
http://nl2.php.net/float
Use round() before you use floor() to get the expected result.

i think u should read the manual about int and float:
http://www.php.net/manual/en/language.types.integer.php
http://www.php.net/manual/en/language.types.float.php#warn.float-precision

Hi,
I was just a bit curious since the project I recently started is huge and
highly modular with the modules communicating to each other. I was looking
into some MVC frameworks - Zend.com, phpro.org, PureMVC.org - to help speed up
the project and its future expandability. After perusing some of the codes,
Zend seems a bit bloated for me even though it already has a lot of good
features built-in and doesn't seem to support modules and the
inter-communcation. Phpro is very straight forward and very light while it
doesn't seem to be able to support a highly sophisticated application with a
lot of modules and the communication between them. PureMVC concept is awesome
but there isn't an official release to support multiple modules (or cores) and
their inter-communication. So I ported the standard to multicore but still
need to see how the modules inter-communication work. I guess I'll have to dig
up some more on the net for examples of the multicore. I haven't yet looked at
the other frameworks, such as CakePHP, symfony, etc. Another plus to PureMVC
is that it is language agnostic design, which I can later easily port my
application to another language should the need arise.
Thanks,
Tommy

What is your conception of "like"?
Have you looked at OpenOffice?

Here is your problem... The form is submitting to submit.php while your
validation is done in form.php. What you should do is have the form submit
TO form.php. If validation passes, redirect via header() [1]. You might
have to use session [2] to have the value accessible in submit.php for
security reasons.

In submit.php, the values should be retrieved from $_SESSION. Also, this is
very bad to SQL injection. Look into escaping the input [3]. I suggest you
to use mysqli extension, if you can, over mysql extension. There many
benefits to it.
