  1. POCache multiple pages/images from Instagram
    text
    copied!<p>I'm working on a small project where the users can see images taged by, in this case, "kitties". Instagram only allows 5000 requests/hour, i don't think it will reach this, but i'm choosing to cache any way. Also because i can't figure out how to get the back-link to work. I can only get the link for next page, then the link for recent page becomes the current page, a link to itself. Also, the api can return strange number of images, some times 14, some times 20 and so on. I want it to always show 20 images per page and only have 5 pages (100 images). And then update this file each 5/10 minutes or something.</p> <p>So, my plan is to store like 100 images into a file. I got it working, but it's incredible slow. The code looks like this:</p> <pre><code>$cachefile = "instagram_cache/".TAG.".cache"; $num_requests = 0; //Just for developing and check how many request it does //If the file does not exsists or is older than *UPDATE_CACHE_TIME* seconds if (!file_exists($cachefile) || time()-filemtime($cachefile) &gt; UPDATE_CACHE_TIME) { $images = array(); $current_file = "https://api.instagram.com/v1/tags/".TAG."/media/recent?client_id=".INSTAGRAM_CLIENT_ID; $current_image_index = 0; for($i = 0; $i &gt;= 0; $i++) { //Get data from API $contents = file_get_contents($current_file); $num_requests++; //Decode it! $json = json_decode($contents, true); //Get what we want! foreach ($json["data"] as $x =&gt; $value) { array_push($images, array( 'img_nr' =&gt; $current_image_index, 'thumb' =&gt; $value["images"]["thumbnail"]["url"], 'fullsize' =&gt; $value["images"]["standard_resolution"]["url"], 'link' =&gt; $value["link"], 'time' =&gt; date("d M", $value["created_time"]), 'nick' =&gt; $value["user"]["username"], 'avatar' =&gt; $value["user"]["profile_picture"], 'text' =&gt; $value['caption']['text'], 'likes' =&gt; $value['likes']['count'], 'comments' =&gt; $value['comments']['data'], 'num_comments' =&gt; $value['comments']['count'], )); //Check if the requested amount of images is equal or more... if($current_image_index &gt; MAXIMUM_IMAGES_TO_GET) break; $current_image_index++; } //Check if the requested amount of images is equal or more, even in this loop... if($current_image_index &gt; MAXIMUM_IMAGES_TO_GET) break; if($json['pagination']['next_url']) $current_file = $json['pagination']['next_url']; else break; //No more files to get! } file_put_contents($cachefile, json_encode($images)); </code></pre> <p>This feels like a very ugly hack, any ideas for how to make this work better?</p> <p>Or someone that can tell me how to make that "back-link" to work like it should? (Yes, i could yes js and go -1 in history, but no!).</p> <p>Any ideas, suggestions, help, comments etc are appreciated.</p>
