formating decimals

[toddmarx]

Ok, have a question. I want to format the decimal places in an equation using variables. Below is the code:

You Save: $<?php echo $row_randomizer['myprice'] - $row_randomizer['saleprice']?>

Basically, it should look something like this:

You Save: $2.50

instead of just $2.5

How Do I get it to force the two decimal places.

Thanks again,
Todd

$amount = sprintf("%01.2f", $amount);

sprintf() is used to format strings.

Edit: amount only has one m.. I'm tired. 😉

Have a look at

http://www.phpbuilder.com/manual/function.number-format.php

[toddmarx]

hmmm

still not working. Here is what I tried....

You Save: $<?php 
			  $number = $row_randomizer['myprice'] - $row_randomizer['saleprice'];
			  number_format($number, 2, '.', '');
			  echo $number

[leatherback]

Change to:

$number = number_format($number, 2, '.', '');

I dont understand. If I do that, then how will php know what number to format? Or will apply the rule to the rest of the script? Sorry to be a bother. Still learning php.😕

[Mordecai]

As a little clarification of what leatherback's change did:
number_format does not change the string, it returns a changed version, and you must reset the variable to this returned value.

It will not reset $number until the value is returned, so it won't recursively call number_format(), as that would go indefinately, and therefore crash PHP.

😃 I C. Ok. I try it now and see if it works. (i'm sure it will)

[leatherback]

I am sorry.

I am quite in depth in my own script -which doesn't want to run- and a bit short in my replies at the moment..

You could of course use:

$formatted_number = number_format($number, 2, '.', '');

(For clarity, and later use of the non formatted number)

The non-formatted numer will run faster (only a very, very minute amount faster, but speed is speed), as it does not have to filter out everything (PHP ignores significant digits--0.700 is not equal to 0.7 in mathematics, but it is in PHP (both are truncated to 0.7)).

leatherback, thanks for taking the time out to help.....

I am still not getting it. Maybe I have just been at it too long today, or I am in the middle of a huge brain fart. I understand what the code is supposed to do, but cant get placed right or something? Sorry to be such a pain in the arse. N E Way, here is the raw code:

You Save: $<?php  echo $row_randomizer['myprice'] - $row_randomizer['saleprice'];

Again, I apologize for the stupidity! 🙂

[toddmarx]

Nevermind! I got it! Thanks! I did not pay attention to the whole formulae. I do apprecieate both of you guys' help. Good luck with your script leatherback! 🙂

Thanks again.

Hey Todd..
Maybe you can help me write my script now ;-)

I am grabbing url's from sites linking to mine, and try to figure out which are search-engines. Soooo much fun...

Happy programming.

[toddmarx]

I'll give it a shot......

How are you storing the referrer? I'd suggest having a line of code in your index file that writes every referrer down in a file, and then use that file. This would be ideal if every one of your pages ran through your index file (i.e. index.html?page=login).

[leatherback]

Hi, that is not really a problem (Got the basics online at www.bio-vision.nl/statistics/report.php).

Now I am dissembling the urls, using specific routines for each browser:

if preg_match("/altavista/i", "$HTTP_REFERER"))
{
$referer = "Altavista";
$keywords = breackup($HTTP_REFERER, 'AV');
}

But now I have a hard time getting the url broken up.

I am using
$urlextent = explode ('?', $HTTP_REFERER);
$urlextend = $urlextend[1];
$extention = explode('&', $urlextend);

to get the subsets of each url. But I cannot grab the variables. Not sure what it going wrong though. Been playing for about an hour. Still no luck..

I'll get there eventually..

hey, I have a program that does that already. It is called super counter or something like that. If you want, email me at [e-mail] and I will send it to you.

To see demo of it go to

Hi,

Is looking nice. But I do not see any stats which will give you an idea of which keywords people use to find your site, and through which search engines?

Also.. My site has a lot of photo's on it. I want to be able to track which photo's are viewed most etcetc. SO I look for specific string combinations in the url.

I have found my error though.. Stupid type, which copied variables from one to another..

Thanks or the offer though.

J.

[toddmarx]

glad you got it working!

I hate it when that happens:

phoiled by phat phingers!

Don't explode the referrer, explode the query string ($_SERVER["QUERY_STRING"]).
