Basically what I have is a sql database with various data points in it (name, email, etc.) and importantly fields that contain addresses. What I am attempting to do is use these addresses (possibly just the zip codes?) to plot pins on a google map with their geocoding system. I know that i need to collect all of the zips from the database in an array and do some sort of foreach for every zip but I am unsure of how to do this. Here is what I have so far, can anyone help me?
<?php
$dbh=mysql_connect('my_database_host.edu','my_database_user','my_database_password');
if (!$dbh)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db('my_database_name', $dbh);
$query = "SELECT fldZip FROM tblLocation";
$findzips = mysql_query($query);
while($row =mysql_fetch_array($findzips)) {
echo $row['fldZip'];
}
?>

Instead of using the Javascript-API to geocode the ZIPs use the geocoding-webservice via PHP.
That also would be a good point to store the LatLng’s inside the DB, so you don’t have to request them again.
