Question

I’m working on a Google Maps project within a PHP application. I need to find a way to store a latitude and longitude pair as a singular value. I’m using this to help store markers with identical coordinates.

Is there way I can encode the latitude/longitude pair into a single string? I would like something like:

$lat = 45.18392;
$long = 62.18293;

// Would return a single string like 893jfd8sj39k
$single_string = make_single_string($lat, $long);

function make_single_string($lat, $long)
{
    // Do something here with $lat and $long
    return $single_string;
}

The most important part of the function is that it must return the same string EVERY time.

Thanks for the help!

I think you are looking for this:

function make_single_string($lat, $long)
{
    $single_string = md5( $lat.'-'.$long );
    return $single_string;
}

result will be something like this:
