How to use Instagr.am photos on your site

Category: Php,Spiders & web botsGiulio Pons @ 4:11 pm

The question is: how can I bring my instagram photos on my personal web site?

With this tutorial you can make this.

I’m addicted to Instagram, I make photos quite every day with it. But I’m also a developer, and I already have a personal portfolio for my photos… which became obsolete since it’s a year that I don’t update it. Instagr.am is only on iPhone. There isn’t your page with photos online, but there are few APIs that can be used to retrieve your photos and infos and, there isn’t any public feed to retrieve photos.

So long: how can I bring my instagram photos on my personal web site? Thanks to followgram.me you can create your “vanity url” that is to say that you can register simply by logging in with your instagram account (oAuth is performed) and create a simple and nice url with your photos, like followgram.me/giuliopons. This page, with his customizable UI, can be OK for many users, but not for me. :-) I want only photos, and nothing else matters.
Since on my vanity URL there is also a feed that publishes, in a public feed, my pictures I’ve decided that this will be my door to my photos, without using the instagram API and their oAuth integration.

I’ve written the following code that read the feed, parse it, get pictures links and infos, store data (not pictures) in a local file (and periodically check if there are new photos without overloading followgram.me server) and output it in a minimalistic html good for any pc, iphone or ipad.

This is the result: www.ku-ku.it

So, if you want to do the same, make your vanity url on Followgram.me and use this code in your site:

This is the content of my index.php file.

<?
ini_set('default_charset', 'UTF-8');

// ----------------------------------------------------------------------
// CONFIG
$instagram_user = "giuliopons"; // your instagram username
$cachetime = 2; // 2 hours
$file = $instagram_user."_instagram.txt"; // file used to cache content
$TITLE = "Foto di Giulio Pons e Roberta Casaliggi con instagr.am"; // your page title
// ----------------------------------------------------------------------

function getFollowgram($u) {
	// function read instagram feed through followgram.me service, thanks Fabio Lalli
	// twitter @fabiolalli
	$url = "http://followgram.me/".$u."/rss";
	$s = file_get_contents($url);
	preg_match_all('#<item>(.*)</item>#Us', $s, $items);
	$ar = array();
	for($i=0;$i<count($items[1]);$i++) {
		$item = $items[1][$i];
		preg_match_all('#<link>(.*)</link>#Us', $item, $temp);
		$link = $temp[1][0];
		preg_match_all('#<pubDate>(.*)</pubDate>#Us', $item, $temp);
		$date = date("d-m-Y H:i:s",strtotime($temp[1][0]));
		preg_match_all('#<title>(.*)</title>#Us', $item, $temp);
		$title = $temp[1][0];
		preg_match_all('#<img src="([^>]*)">#Us', $item, $temp);
		$thumb = $temp[1][0];
		$ar['date'][$i] = $date;
		$ar['image'][$i] = str_replace("_5.jpg","_6.jpg",$thumb);
		$ar['bigimage'][$i] = str_replace("_5.jpg","_7.jpg",$thumb);
		$ar['link'][$i] = $link;
		$ar['title'][$i] = $title;
	}
	return $ar;
}

function checkValidFile($f,$hours) {
	// Function thar check if a file is older than X hours
	$durata=60*60 * $hours;
	$daquanto=$durata+1;
	if (file_exists($f)) $daquanto=time()-filemtime($f); else return false;
	if ($daquanto<=$durata) {
		// existing file is still valid
		$t = ($durata-$daquanto);
		$s = $t % 60;
		$m = floor($t/60) % 60;
		$h = floor($t/3600) % 24;
		$g = floor($t/3600/24);
		return true;
	} else {
		// existing file is old
		return false;
	}
}

// -----------------------------------------------
// load cached file
if (!file_exists($file)) $archive=""; else {
	$rHandle = fopen($file, 'r');
	$archive = fread($rHandle, filesize($file));
	fclose($rHandle);
}

// -----------------------------------------------
// check for new feed every X hours
if(!checkValidFile($file, $cachetime)) {
	$r = getFollowgram($instagram_user);
	// add new images to archive file
	for ($i=floor(count($r,COUNT_RECURSIVE)/count($r)); $i>=0; $i--) {
		if($r['image'][$i]) {
			$temp = "<li><img src='".$r['image'][$i]."'/><span>".$r['date'][$i]."<br/>".$r['title'][$i]."</span></li>";
			if(!stristr($archive,basename($r['image'][$i]))) $archive = $temp.$archive;
		}
	}
	// save new file
	$f = fopen($file,'w');
	fwrite($f,$archive);
}

PHP to post on a Facebook page

Category: Php,Spiders & web botsGiulio Pons @ 4:18 pm

Hi, I’ve modified the Mini Bot Class, I’ve fixed the Facebook status update and I’ve implemented the function to post on the wall of a facebook page: suppose you have a page of a brand, and you need to update it regularly with a cron job… Very, very usefull, isn’t it?

Nothing more to say. Just download the class from Mini Bot Class page and search for setFacebookStatus method and postToFacebookPage method.

PHP google images mini bot

Category: Php,Spiders & web botsGiulio Pons @ 1:34 pm

This simply php function will retrieve the links of the images from Google Images searched with a keyword. The function just calls images.google.it and parse the html to find the url of the images, in this case the urls are stored in the javascript, so the parsing doesn’t use any html tag to find data. It builds an array of urls and return it.

function getGoogleImg($k) {
	$url = "http://images.google.it/images?as_q=##query##&hl=it&imgtbs=z&btnG=Cerca+con+Google&as_epq=&as_oq=&as_eq=&imgtype=&imgsz=m&imgw=&imgh=&imgar=&as_filetype=&imgc=&as_sitesearch=&as_rights=&safe=images&as_st=y";
	$web_page = file_get_contents( str_replace("##query##",urlencode($k), $url ));

	$tieni = stristr($web_page,"dyn.setResults(");
	$tieni = str_replace( "dyn.setResults(","", str_replace(stristr($tieni,");"),"",$tieni) );
	$tieni = str_replace("[]","",$tieni);
	$m = preg_split("/[\[\]]/",$tieni);
	$x = array();
	for($i=0;$i<count($m);$i++) {
		$m[$i] = str_replace("/imgres?imgurl\\x3d","",$m[$i]);
		$m[$i] = str_replace(stristr($m[$i],"\\x26imgrefurl"),"",$m[$i]);
		$m[$i] = preg_replace("/^\"/i","",$m[$i]);
		$m[$i] = preg_replace("/^,/i","",$m[$i]);
		if ($m[$i]!="") array_push($x,$m[$i]);
	}
	return $x;
}

This function will be included in the next version of Mini Bot Class.
