Hi guys,Today I am going to teach you about one function of PHP which will help you to get geolocation
(i mean latitude and longitude of location) then you can set them in google maps and show location of image where image is taken.
We routinely took images in camera but if our phone camera's geo location is ON then it will automatically recorded where this image is taken.
So for testing took one image which have geo location information stored and get it's information.store your image in one folder and give then folder name in $dir variable.
Please check out below code:
<?php
$dir = "./img";
function readGPSinfoEXIF($image_full_name)
{
$exif=exif_read_data($image_full_name, 0, true);
if(!$exif || $exif['GPS']['GPSLatitude'] == '') {
return false;
} else {
$lat_ref = $exif['GPS']['GPSLatitudeRef'];
$lat = $exif['GPS']['GPSLatitude'];
list($num, $dec) = explode('/', $lat[0]);
$lat_s = $num / $dec;
list($num, $dec) = explode('/', $lat[1]);
$lat_m = $num / $dec;
list($num, $dec) = explode('/', $lat[2]);
$lat_v = $num / $dec;
$lon_ref = $exif['GPS']['GPSLongitudeRef'];
$lon = $exif['GPS']['GPSLongitude'];
list($num, $dec) = explode('/', $lon[0]);
$lon_s = $num / $dec;
list($num, $dec) = explode('/', $lon[1]);
$lon_m = $num / $dec;
list($num, $dec) = explode('/', $lon[2]);
$lon_v = $num / $dec;
$gps_int = array($lat_s + $lat_m / 60.0 + $lat_v / 3600.0, $lon_s
+ $lon_m / 60.0 + $lon_v / 3600.0);
return $gps_int;
}
}
function dirImages($dir)
{
$d = dir($dir);
while (false!== ($file = $d->read()))
{
$extension = substr($file, strrpos($file, '.'));
if($extension == ".jpg" || $extension == ".jpeg" || $extension == ".gif"
|$extension == ".png")
$images[$file] = $file;
}
$d->close();
return $images;
}
$array = dirImages('./img');
$counter = 0;
foreach ($array as $key => $image)
{
echo "<br />";
$counter++;
echo $counter;
echo "<br />";
$image_full_name = $dir."/".$key;
echo $image_full_name;
$results = readGPSinfoEXIF($image_full_name);
$latitude = $results[0];
echo $latitude;
echo "<br />";
$longitude = $results[1];
echo $longitude;
echo "<br />";
}
?>

Try above code and you will get one fantastic result.
