get users geo location and echo out mysql results based on location? - php

Question

Hi i am trying to find our what city my users are in from their ip address to be able to display a list of users in my database close to them/in their area.
I have been looking at this api:
http://ipinfodb.com/ip_location_api.php
and i have registered and got an api key, but im not sure where to go from here. Here is the example code they have used to get the users location:
<?php
include('ip2locationlite.class.php');
//Load the class
$ipLite = new ip2location_lite;
$ipLite->setKey('<api key>');
//Get errors and locations
$locations = $ipLite->getCity($_SERVER['REMOTE_ADDR']);
$errors = $ipLite->getError();
//Getting the result
echo "<p>\n";
echo "<strong>First result</strong><br />\n";
if (!empty($locations) && is_array($locations)) {
foreach ($locations as $field => $val) {
echo $field . ' : ' . $val . "<br />\n";
}
}
echo "</p>\n";
//Show errors
echo "<p>\n";
echo "<strong>Dump of all errors</strong><br />\n";
if (!empty($errors) && is_array($errors)) {
foreach ($errors as $error) {
echo var_dump($error) . "<br /><br />\n";
}
} else {
echo "No errors" . "<br />\n";
}
echo "</p>\n";
?>
but how would i now set a mysql query that says if the user location is london and users are listed as in london in the database then to display these to the user?
i would really appreciate a push in the right direction here if anyone can help, thanks.

Here is an example (without knowing your database structure and untested ;). Insert this in the foreach ($locations as $field => $val) loop as below:
foreach ($locations as $field => $val) {
echo $field . ' : ' . $val . "<br />\n";
$mysqli = new mysqli('<mysql server>', '<mysql user>', '<mysql password>', '<database>');
if(mysqli_connect_errno()) {
echo 'Error: Unable to connect to Database; ';
} else {
if ($stmt_evt = $mysqli -> prepare('SELECT <other_users>, ... FROM <your table> WHERE <user_location> LIKE ? ORDER BY <whatever>')) {
$stmt_evt -> bind_param('s', $val);
$stmt_evt -> execute();
$stmt_evt -> bind_result($<other_users>, $...);
while ($stmt_evt->fetch()) {
echo 'Other users in your area: '.$<other_users>;
}
} else {
echo 'Error: Unable to prepare Event statement.';
}
}
}
