New idea for finding people

November 9, 2014

I am playing with a new website idea for searching various social network platforms all in a single search. The beta site is:

You authorize the social networks you want to search and then type in the name of the person you’re searching for. Currently the beta supports Facebook, Twitter and Instagram. Plan to add more down the road. What are your thoughts? Shoot me some feedback.

Resizing High Resolution (Hi-res) JPEG Images with PHP

October 13, 2014

I kept running into a problem when I uploaded high resolution (14MP) images and tried creating thumbnails with them. The issue turned out being the PHP script ran out of memory. So it was a simple increase to about a half gig (512MB) and the script ran perfectly. Here’s the code:


ini_set ( "memory_limit", "512M");
echo createThumb($_GET["src"],$_GET["w"]);

function createThumb( $path, $thumbWidth ) 
    $info = pathinfo($path);
    // continue only if this is a JPEG image
    if ( strtolower($info['extension']) == 'jpg' ) 

      // load image and get image size
      $img = imagecreatefromjpeg( "{$path}" );
      $width = imagesx( $img );
      $height = imagesy( $img );


      // calculate thumbnail size
      $new_width = $thumbWidth;
      $new_height = floor( $height * ( $thumbWidth / $width ) );

      // create a new temporary image
      $tmp_img = imagecreatetruecolor( $new_width, $new_height );

      // copy and resize old image into new image 
      imagecopyresized( $tmp_img, $img, 0, 0, 0, 0, $new_width, $new_height, $width, $height );
	  $exif = exif_read_data($_GET["src"]);
	  $orientation = $exif["Orientation"]; //6 for portrait and 1 for landscape
	  if($orientation == 6 && $width > $height) {
	  	$tmp_img = imagerotate($tmp_img, 270, 0);
      return imagejpeg($tmp_img);

New Twitter API (v1.1) Quick Start

October 10, 2014

This tutorial will help you get started with the new Twitter API which will be much different than the deprecated 1.0 version. In this example we’ll look at how to get a user’s timeline via the API.

  1. Setup your developer account if you haven’t done so yet at
  2. Go to and create your app
  3. Once created click on the Keys and Access Tokens tab and Create Access Tokens (for this example we only need Read access but for other applications you may want read and write)
  4. Copy and paste contents of TwitterAPIExchange.php
  5. Create a new PHP file that includes the TwitterAPI Exchange and uses your access tokens to GET requests from Twitter API:
    /** Set access tokens here - see: **/
    $settings = array(
        'oauth_access_token' => "",
        'oauth_access_token_secret' => "",
        'consumer_key' => "",
        'consumer_secret' => "",
        'username' => 'jolamar',
        'count' => 2
    $url = '';
    $getfield = '?screen_name='.$settings["username"].'&count='.$settings["count"];
    $requestMethod = 'GET';
    $twitter = new TwitterAPIExchange($settings);
    $feed = json_decode($twitter->setGetfield($getfield)
                 ->buildOauth($url, $requestMethod)
                 ->performRequest(), true);
    foreach($feed as $tweet) {
        // twitter variables
        $created = date("j M Y", strtotime($tweet["created_at"]));
        $id = $tweet["id"];
        $text = $tweet["text"];
        $username = $tweet["user"]["screen_name"];
        $name = $tweet["user"]["name"];
        $retweet_count = $tweet["retweet_count"];
        $favorite_count = $tweet["favorite_count"];
        $hashtags = $tweet["entities"]["hashtags"]; //array
        $mediaItems = $tweet["entities"]["media"]; //array
        echo "<div class='liljoshTweet'>
        <div class='liljoshName'><a href='$username'>$name</a></div><!-- /.liljoshName -->

        if(is_array($mediaItems)) {
            foreach($mediaItems as $media) {
                $media_url = $media["media_url_https"];
                $media_link = $media["expanded_url"];
                $width = $media["sizes"]["small"]["w"];
                $height = $media["sizes"]["small"]["h"];
                echo "<div class='liljoshImage'><a href='$media_link' target='_blank'><img src='$media_url' /></a></div><!-- /.liljoshImage -->";
        echo "</div><!-- /.liljoshTweet -->";
    function makeClickableLinks($s) {
      return preg_replace('@(https?://([-\w\.]+[-\w])+(:\d+)?(/([\w/_\.#-]*(\?\S+)?[^\.\s])?)?)@', '<a href="$1" target="_blank">$1</a>', $s);
