Here is how to get a GoPro’s image data (EXIF) such as size, settings, configuration and location using PHP and exif_read_data().

I have already covered getting image EXIF data in PHP see here so the concept is exactly the same except a GoPro has more/different values in the returned data than a regular camera would.

Simply grab an image taken from a GoPro define it at $image_file = ''; and run the below PHP code to see all the available EXIF data:

$image_file = '';
$exif = exif_read_data($image_file, 0, true);
foreach ($exif as $key => $section) {
    foreach ($section as $name => $val) {
        echo "$key.$name: $val<br />\n";
    }
}

The GPS data (if the GoPro had it turned on) is formatted in extra array’s and not in simple Latitude x Longitude format.

With the help of a function found here it can easily get turned into a useable format.

Running the code below the data returned was

This can be helpful if you wanted to create an image database, compress your photos and make a thumbnail by executing a for all jpg in folder.

Full code with output:

<?php
$image_file = 'GOPR1280.jpg';

$exif = exif_read_data($image_file, 0, true);
$file_name = $exif["FILE"]["FileName"];
$model = $exif["IFD0"]["Model"];
$software = $exif["IFD0"]["Software"];
$size = $exif["FILE"]["FileSize"];
$date_time = $exif["IFD0"]["DateTime"];
$width = $exif["COMPUTED"]["Width"];
$height = $exif["COMPUTED"]["Height"];
$aperture = $exif["COMPUTED"]["ApertureFNumber"];
$shutter_speed = $exif["EXIF"]["ExposureTime"];
$iso = $exif["EXIF"]["ISOSpeedRatings"];
$focal_length = $exif["EXIF"]["FocalLength"];
$contrast = $exif["EXIF"]["Contrast"];
$saturation = $exif["EXIF"]["Saturation"];
$sharpness = $exif["EXIF"]["Sharpness"];
$white_balance = $exif["EXIF"]["WhiteBalance"];
$digital_zoom_ratio = $exif["EXIF"]["DigitalZoomRatio"];
$fl_calc = eval('return ' . $focal_length . ';');
$focal_length_mm = "$fl_calc mm";

$exif2 = exif_read_data($image_file);
$latitude = gps($exif2["GPSLatitude"], $exif2['GPSLatitudeRef']);
$longitude = gps($exif2["GPSLongitude"], $exif2['GPSLongitudeRef']);
