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>', $s);
    function makeHashtagLinks($s) {
    return preg_replace('/(^|\s)#(\w*[a-zA-Z_]+\w*)/', '\1<span class="liljoshHashtag">#</span><a href="\2?src=hash" target="_blank">\2</a>', $s);

Remove .php extensions with .htaccess

September 29, 2014

You can clean up your URL a little by automatically removing the .php extensions and index files using mod_rewrite. This requires your web server has Apache running the mod_rewrite module. Create an .htaccess file in your web root directory with this content:

# Author: Lil Josh (
# Date: Sept 2014
# Description: Clean up the URL by removing the .php extension and index file
RewriteEngine On
RewriteBase /
# Unless directory, remove trailing slash
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/$ $1 [R=301,L]
# Redirect external .php requests to extensionless url
RewriteCond %{THE_REQUEST} ^(.+)\.php([#?][^\ ]*)?\ HTTP/
RewriteRule ^(.+)\.php$ http://%{HTTP_HOST}/$1 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}\.php -f
RewriteRule ^([^\.]+)$ $1.php
# Remove index file
RewriteRule ^(.*)index\.(html|htm|shtml|php)$ http://%{HTTP_HOST}/$1 [R=301,L]
