Hey John,
I dont think its the browser because I have tried this with opera 6,opera 7,
IE and NN with the same results...
But when i checked the phpinfo() it says that cookies are enabled....Do you
think its worth it to search and replace each Location header with .SID?
Well, if SID has a value, that means the session cookie could not be
set. Plain and simple.

My goal is to input the amount of Bytes used by a user as $inputbox and
calculate how many kbs,megs,gigs along with $cost for the price per meg.
<?
$inputbox = "414478244";
// PROCESS DATA
$kbs = $inputbox/1024;
$megs = $kbs/1024;
$gigs = $megs/1024;
// CALC COST OF MEGS
cost = $megs * 0.05;
// OUT PUT DATA.
echo"<b>$inputbox bytes = </b><br>$kbs kb.<br>$megs meg @ $0.05c per Meg =
\$$cost<br>$gigs gig.<br><br>";
?>
This is what I get outputted.
414478244 bytes =
404763.910156 kb.
395.277256012 meg @ $0.05c per Meg = $19.7638628006
0.386012945324 gig.
Questions?
1. Should I be dividing by 1024 or 1000? This was passed to me by word of
mouth ...
2. Any way of rounding to 2 or 3 digests after the decimal point.
3. to remove any , from the inputted string.

1) 1024 is more correct, so, use it unless what you're given was
(incorrectly) calculated with 1000.
2) round($number, 2) - http://us4.php.net/manual/en/function.round.php
3) Use a search and replace (regular expression) to replace commas with
empty strings. ereg_replace("," "", $string) -

Use 1024, only marketers seem to be able to get away with using
1000.

see round() and number_format() in the manual.

see str_replace()

to go further with this you could make sure they enter a valid
number:
$string = ereg_replace("[^0-9.]", "", $string);

This would happen when a incoming or a outgoing port 20 (FTP Data)
connection can't be made.
I don't know how PHP ftp functions work but normally the FTP client makes a
outgoing connection on port 21, and then the FTP Server makes a incoming
connection from port 20 when any kind of data is sent (ie directory
listings, or files)....
So I'm guessing that the web server that you are running ftp_put on doesn't
allow incoming connections...
You can try getting around this by setting PHP to use Passive mode, which
makes the FTP client connection out to port 20 on the FTP server. A quick
look at the manual says that you should use ftp_pasv to make that happen.
Hope this helps
Andrew

I finally set up an Apache Web Server. I didn't realize you needed that to
run php until now.
Now, I have another question.
I have it installed, but when I run a PHP script, it says it can't be found.
Even when I am running the apache server. And the apache server seems to be
running fine.

No one is going to be able to help you since you have provided not
enough information.
Did you read the installation for your paticular setup:

That's only true if you need to serve Web pages; php runs fine from the
command line ...

I've been using PHP for a few years now and I'm quite familiar and
comfortable with it.
I'd like to start to seriously do some OOP coding and "take things to
the next level". But as I understand it, PHP5 is going to make quite a
few changes/improvements to PHP4's current handling of OOP.
Given that the PHP5 beta has been out for approx. 1 month, do you think
it makes sense to try to get into OOP with PHP4 right now when things
could change in a fairly short while (not sure how long it'll be until
PHP5 is released) and then have to re-learn certain aspects of OOP after
getting comfortable with it? Or do you think that the change from 4 to 5
won't really be that big of a deal?
I know that many people ask OOP-related questions a lot on the board,
but I was just wondering what everyone thought of the jump from 4 to 5
and about trying to start learning OOP *right now*.
Thanks

Hi Mike,
The short answer:
Yes.
The long answer:
PHP 5 only adds functionality to PHP 4, it is backwards compatible, so
start with PHP 4, and PHP 5 will be easy.

I'd say get a good book on OO thinking/methodology and read that. Do a
little practicing in PHP4, but I'd wait until PHP5 to really get into
it. PHP5 is supposed to have a lot more OO features.
My $0.02, of course. I just got "The Object Oriented Though Process" by
SAMS from someone through Amazon. Looks to be a good book.

Yes, it can be better to pass in a variable (by reference if you need
to write to it from within a function and not have it as the value
that you return), e.g.
function doSomething(&$a){
$a = 20;
return true; // to signify success
}
$a = 10;
doSomething($a);
echo $a; // prints 20

Hi there Binay
Have a look at http://smarty.php.net - this is a very good templating
engine.
You could also consider creating your own if you have specific needs. We
created our own pre-parser (built in PHP but soon to be ported to an Apache
module) that works really well for us
Best regards
Adrian

I have some URLs in hrefs that have an &. This does not validate HTM4.01
transitional, so I want to replace them with &
So I buffer the output and do a replace, but suppose there is already an
& then I get &amp; or if I have anything else like " then I get
&quot;
Any ideas on how to do this the right way???
Thanks!
Shawn

How about you decode the string, and then encode it like so:
$decode = html_entity_decode($input);
$output = htmlentities($decode);
If you have the string
ab&something&blah
the decode will turn that into
ab&something&blah
and then encode it into
ab&something&blah
This can run into problems, but they will be just the same problems you
would receive with any other method... The problem I speak of is when your
input string is "something&" and & isn't a HTML Entity but the
proper string just so happened to have a & in it just before the amp... In
that case the amp; would be incorrectly removed... However the chances of
having a string that matches a HTML entity with a "bad" & placed in front of
it are so high that you shouldn't worry (and you did mention it was a URL,
so as far as I know ; can't appear in a valid URL, so I don't think you
should worry at all :))... And if you are worrying then any method you chose
will have this problem and you should do the task by hand :)
Hope this helps
Andrew

It seems that your php isn't compiled with pdf.
