<?php

// Replace YOUR_APP_ID and YOUR_APP_SECRET with your actual app ID and app secret
$app_id = 'YOUR_APP_ID';
$app_secret = 'YOUR_APP_SECRET';

// Replace YOUR_HASHTAG with the hashtag you want to search for
$hashtag = 'YOUR_HASHTAG';

// Get an access token by making a POST request to the Instagram API
$access_token_url = 'https://api.instagram.com/oauth/access_token';
$access_token_data = [
  'client_id' => $app_id,

// The $result variable now contains the data for the photos with the specified hashtag
// You can access the data for each photo like this:
foreach ($result->data as $photo) {
  $photo_url = $photo->images->standard_resolution->url;
  // Do something with the photo URL, like print it or save it to a database
  print $photo_url . "\n";
