README

This module takes an Instagram URL and returns a data structure as if the URL had been marked up with a proper h-entry.

Usage

Bring in this library using composer, or just by including the src\p3k\instagram-shim.php file.

{
  "p3k/mf2-instagram-shim": "0.1.*",
}

First, initialize the Instagram client with your credentials.

p3k\instagram\setup($instagramAccessToken);

Then you can call parseURL with a URL to a photo and get back a nicely formatted h-entry.

$data = p3k\instagram\parseURL('http://instagram.com/p/rhlnwxjcu9/');

Timezone

Instagram returns unix timestamps and does not include timezone information anywhere. However, photos that are taken at a location can be assumed to be in that timezone. To augment the parsed result so that the returned dates include timezone, you can provide a function that will be used to look up the timezone of photos if location data is available.

The function should take two arguments, latitude and longitude, and return a string of the timezone name such as "America/Los_Angeles".

The code below will return the same timezone for all locations in the case that you want all your photos to be set to the same timezone.

p3k\instagram\timezoneLookup(function($lat,$lng){
  return 'America/Los_Angeles';
});

The code below will use a remote web API to find the timezone given a location.

p3k\instagram\timezoneLookup(function($lat,$lng){

  $ch = curl_init('http://timezone-api.geoloqi.com/timezone/' . $lat . '/' . $lng);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
  $response = curl_exec($ch);
  if($response) {
    $timezone = json_decode($response);
    if($timezone) {
      return $timezone->timezone;
    }
  }

  return null;
});
