Yeah, mine actually does.  It's from 2006 and 2007 data, actually.

The free one is from an OLD US census, paid for by taxpayers, and
therefore Public Domain.

$1,000 ones (should) include new zips (lots) and up-to-date population
info etc.

Re: [PHP] zip codes and lat/longs

[mike]

You can use the formula to figure out how many zip codes are within the radius

Here's a snippet of old code that did that:

$radius = 50; // in miles

$uchk = db_query("SELECT uz.zip FROM user_zip WHERE uid=$visitor[uid]");
if(db_numrows($uchk) == 1) {
list($vz) = db_rows($uchk);
$zchk = db_query("SELECT latitude,longitude
FROM z_data_zips WHERE zip=$vz");
list($vlat,$vlong) = db_rows($zchk);
db_free($zchk);
$zips = db_query("SELECT z.zip FROM data_zips
z WHERE CEIL(69*DEGREES(ACOS(SIN(RADIANS(z.latitude)) *
SIN(RADIANS($vlat)) + COS(RADIANS(z.latitude)) * COS(RADIANS($vlat)) *
COS(RADIANS(z.longitude - $vlong) < $radius");
$ziplist = "";
if(db_numrows($zips) > 0) {
while(list($zip) = db_rows($zips)) {
$ziplist .= "'$zip',";
}
db_free($zips);
$ziplist =
substr($ziplist,0,strlen($ziplist)-1);
$query .= " user_zips IN($ziplist)";
}
}
db_free($uchk);

RE: [PHP] zip codes and lat/longs

I'm entertaining how to determine what zip codes fall within a 50 
mile radius of another zip code.

Anyone done this before?

Also, does anyone have any sources for zip codes and lat/long databases?

TIA for any help/suggestions.

Here is a code snip that I use to determine things within a certain
radius (5 miles) of a zip code;

/* calcs for distance */
function distance($lat1, $lon1, $lat2, $lon2) { 
$theta = $lon1 - $lon2; 
$dist = sin(deg2rad($lat1)) * sin(deg2rad($lat2)) +
cos(deg2rad($lat1)) * cos(deg2rad($lat2)) * cos(deg2rad($theta)); 
$dist = acos($dist); 
$dist = rad2deg($dist); 
$miles = $dist * 60 * 1.1515;

Re: [PHP] zip codes and lat/longs

[mike]

After reading this I decided to figure out what the issue was.

It was the MySQL result set. Somehow the columns changed and messed up
the float values. So I just whipped this up quick to reload the data
(and possibly update it too)

Here's the quick-and-dirty:

1) download ZCTA (the text version) from
http://www.census.gov/geo/www/gazetteer/places2k.html
2) run this

db_query("TRUNCATE TABLE data_zips");

$fp = fopen('zcta5.txt', 'r');
while(!feof($fp)) {
$line = fgets($fp, 2048);
$line = chop($line);
$zip = substr($line, 2, 5);
$lat = substr($line, 137, 9);
$long = substr($line, 146, 12);
db_query("INSERT INTO data_zips(zip, latitude, longitude)
VALUES('$zip', '$lat', '$long')");
}
fclose($fp);

schema:

CREATE TABLE `data_zips` (
  `zip` mediumint(5) unsigned zerofill NOT NULL default '0',
  `latitude` float(9,6) NOT NULL default '0.00',
  `longitude` float(9,6) NOT NULL default '0.00',
  PRIMARY KEY  (`zip`),
  KEY `latitude` (`latitude`),
  KEY `longitude` (`longitude`));

I believe now you have everything you need :)

You sell it, you can have 50% of whatever revenue it generates,
without having to do a bit of code.

It took me over a year to compile all of the information.  I know
I probably could've found it somewhere else for a few hundred dollars,
but I wanted to do it as a project for myself so I did.  ;-P

Re: [PHP] zip codes and lat/longs

[mike]

Here's code I had, but it recently stopped working

It takes the zip code for the user and the user you're viewing, looks
them up from the data table (z_data_zips) and does the calculation.
The formula is in a handful of places - I converted mine from a MySQL
example (I think, or vice versa)

You can get the zip code lat/long info from the Census Bureau

I believe this is where you get the file:
http://www.census.gov/geo/www/gazetteer/places2k.html

You want the "ZCTAs (ZIP Code Tabulation Areas): (33,233 records)"
file - the schema is at the bottom of the page.

Perhaps someone else might also find the error in my code below that's
changed and save me the time to figure out why it no longer works :)
(for all I know it could be a problem with MySQL result set too)

if($visitor['uid'] > 0) {
$uchk = db_query("SELECT up.country,uz.zip FROM user_profile
up LEFT JOIN user_zip uz ON uz.uid=up.uid WHERE up.uid=$visitor
[uid]");
if(db_numrows($uchk) == 1) {
list($vc,$vz) = db_rows($uchk);
$vz = intval($vz);
$user_zip = intval($user_zip);

$zchk1 = db_query("SELECT latitude,longitude
FROM z_data_zips WHERE zip=$user_zip");
list($ulat,$ulong) = db_rows($zchk1);
db_free($zchk1);
$zchk2 = db_query("SELECT latitude,longitude
FROM z_data_zips WHERE zip=$vz");
list($vlat,$vlong) = db_rows($zchk2);
db_free($zchk2);
$distance =
number_format(ceil(69*rad2deg(acos(sin(deg2rad($ulat)) *
sin(deg2rad($vlat)) + cos(deg2rad($ulat
)) * cos(deg2rad($vlat)) * cos(deg2rad($ulong - $vlong));
echo "Distance from
you: $distance miles.\n";

}
db_free($uchk);
}

If you can figure out how to make sense of this, you might be able to find

If you come up with something useful, keep the list informed.

Thanks for the sarcasm, it definitely helps.

Why is it that when people ask a question there is always someone that has a
smartass answer?

Well, you *could* have a form that displays asking for their zip code;
on submission, it sets a cookie with their zip code, and this allows
them to see their personalized movie times on subsequent visits. (You
could even hide the zipcode form if the cookie is set)

Okay, I run a movie news site and wanted to use it to make it even quicker
for users to find movie times in their area whether they were logged in or
not, but that's the way it goes.

Thanks fo rthe replies.

Is there any way to use PHP to determine the zip code someone is
visiting
from, assuming they are all from the US?
[/snip]

You would have to determine their IP, which, some being dynamically
assigned at log on, would not necessarily indicate the users location.
Then you would have to be able to map the IP to a zip code. The short
answer is no.

Do you mean other than asking them, like using their IP address?
