PHP :: I Write A Date Calculator, But There Always Get A One-day-distance Wrong

Date()'s Wrong.
so I'm using

echo date ("r");

and it's returning the time an hour late. Is that set wrong on the server? And if so how to go about fixing that. email them I guess? I mean, I guess I could learn to parse nist.gov output, but that seems like alot of trouble for something so small. Since I don't have another box to check with, could someone click my site link below and tell me if the time in the nav bar is late for them also?

Date Function Sometimes Returns The Wrong Day
I have the following php code:

function Today2SQLDatetime () {
$today = date ("Y-m-d H:i:s");
print "date ("Y-m-d H:i:s") returned $today<br>";
return $today;
return date ("Y-m-d H:i:s");
} // Today2SQLDatetime

Most of the time this works just fine. For today, for example, it
returns "2005-02-11 xx:xx:xx". But sometimes, for some odd reason it
returns "2005-02-12 xx:xx:xx"! My theory is that since this is on my web
page and since PHP is running under Apache and since this happens every
once in a while that perhaps one of Apache's subprocess has the wrong
idea of my time zone and is actually pointed into tomorrow. Any ideas?

Date Displaying And Storing In MySQL While In Wrong Timezone
I've only used php to display the current date but I can see that I'm not in the same timezone as the server is. Its 5 hours ahead and I can't get it to show the date as Eastern Time.

I'm developing a site for a non-profit slopitch league so they can submit score sheets and track their season. 2 teams must submit a score sheet for their team within 72 hours of having played the game. Then they are not allowed to enter the score sheet without the administrator's permission. Code:

Group-Office / IMAP EMail - Wrong Date Display ??!!
I installed the Community Version of the Group-Software GroupOffice (http://www.group-office.com) on my Webserver.

Group-Office got a module for webmail (IMAP/POP3 eMail-Server). I copied my mail on my IMAP-Server. There are two diffentent views form the mails, a Listview and a Detailview of the selected mail. I think in the Listview there is a wrong eMaildate - It´s the date the mail saved on the server.

In my case there are many mails with the same date, because I copied a lot of them at the same day in the IMAP Folder. The Detailview displays the right emaildate, the date of sending the mail.

There are two different PHP-Files, one for the listenview (messages.php) und one for the datailview (message.php). I think I found the lines of each file for retrieving and displaying the dates. Code:

Sort Distance
I am a newbie at php and would like to know how i would go about sorting ads by distance. The distance is currently echo'd using the following method.

$d = round(distance($lati[0], $long[0], $lati[1], $long[1],"M"));
echo $d;

at the moment the $d is using distance which is a function that calculates the distance between two given postcodes using an sql table in the database. I have got it to work so far so that it displays the distance in miles beside each ad but would now like to know how I would go about ordering or sorting the ads by $d echo'd.

Zip Distance In A Square, Not Radius
I have successfully created a zip code radius search, but the performance is
unacceptable.

I have two tables. The first is 52K zip codes w/lat and long. The second is
3K national business addresses.

Using the zip code 10010, it takes almost 60 seconds to return 122
businesses within a 25 mile radius. This slowdown is almost entirely due to
the query radius distance formula.

I wonder if someone knows the formula to calculate the distance within a
given square. Would this increase performance? I presume the results would
include zips in the "corners", but performance boost might be worth it.

ORDER BY Zip Code Distance
I have successfully converted the ASP code included in the following article
to PHP:

As described the high and low latitudes and longitudes are pre-calculated
and passed to the query.

SELECT *
FROM Locations
WHERE Latitude <= $HighLatitude
AND Latitude >= $LowLatitude
AND Longitude >= $LowLongitude
AND Longitude <= $HighLongitude

I then calculate the actual distance using the latitude and longitude for
each zip returned.

This works great and saves lots of cycles. The downside to this technique is
the inability to sort by distance. Can someone suggest a simple way to
calculate and ORDER BY distance within the query?

I want to search for ads around my zip code for a range of 20 miles. The class I have will find all the zips and get their distances plus will sort them by closest to farthest.

Creating Calculator
My dad would like an online calculator created for his grain buisness. It is going to allow customers to type in their grains moisture and the amount of grain, then when the calculate button is pushed the customer will find out how much it will cost them to do dry their grain.

I was doing well converting my dad's Microsoft Excel spreadsheet formulas into the calculator form when I got stuck. Part of my dads formula wants to match the moisture level that the customer originally typed in, with a cordinationg price. In order for this to work I'd need two very long collums of moisture levels/prices.

How do I get my calculator to use some form of a spreadsheet to get information? Is it even possible?

Control Calculator Expression Logic
I am building a PHP scientific calculator, users can perform calculation by just typing like normal mathematical expressions, e.g "(2+3-4^6)/33.3* 4!" so the result will be calculated accordingly, but I have a problem that, when malicious users try to put a mathematical expressions that is very long enough and takes a very heavy load of processing which might make my web server down. Such as

"9999999999999999999999999999999999999999999999999999999 * 999999999999999999999999999999"

So I thought of limiting the expressions that users can input up to 50 characters long, but this is still not a good idea, because heavy calculations does not necessarily depends on the length of the expressions, such as

//This does not make my computer load heavily
"1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1"

//But this one takes quite long and consume high processing power.
"999999999^99999"

So I want to know, is there a logic that can actually determines the result which might consume high processing which can solve my problem ? or is there a good scientific calculator library that you might want to share ?

Credit Card Monthly Balance Calculator
I want to make a calculator that shows what your interest rate would be.
The key is that it would output a new row per month with the interest charge, the next payment, etc. Not the single line, generic ones that are all over the web.

Sample:
User inputs:
- Loan amount
- Interest rate
- minimum payment rate (usually between 1-3%)
- monthly payment desired

Here is the meat:
The output would return anywhere from 1-400 rows, each explaining the current balance and the interest accrued for that month.

Wrong Headers
I just transfered and patched up some files because I moved them from Linux/PHP/Apache/mySQL to Windows XP Home/PHP/Apache/mySQL.

I fixed all the problems that come up, but, when I load the page in IE6, it reloads a bunch of times and just loads normally.

I tried the best I can to make the page HTML 4.01 Transitional. So, on Linux, after I patched the page to be HTML 4.01 Transitional I put a link for my visitors to validate my page if they want to.

So I notice also, that when I validate the page, I rarely get it to work. 90% of the time, this is what I receive from the W3C validator:

Quote: I got the following unexpected response when trying to retrieve <http://*****/>:

500 Bad header: ' <img src="/images/menu/other_stuff-off.gif" alt="Other Stuff" name="menu-other_stuff" width="186" height="17" border="0">'

Please make sure you have entered the URI correctly.

I get this error most of the time, but sometimes there is a different part of my PHP HTML output in the page. And then, when it works, half of the page is trimmed off, thus, I get errors about my page not being HTML 4.01 Transitional.

I tried a couple experiments with my layout code, and the same code makes the browser reload, and reload... I've tried debugging my layout code but it brought up nothing...

I switched from the PHP module to using the CGI executable. Some things changed: The page no longer reloads repetitively; when the validator fails, I sometimes get a 'Header too long' message; using the validator brings success more often, but other letters are in the output (degree marks, little squares -- these don't appear when viewing the source of the page in IE6).

Anybody know why this header is being sent by my server?

*Note* I am not trying to load an image. I am trying to load a dynamic PHP page.
