Primarily the focus on this tutorial is to display your cached tweets using PHP and OAuth on your website. We will be accessing the secure Twitter 1.1 API with PHP by parsing and caching the JSON file to store on your server. It may seem a lot of code just to display your latest tweets on your website but the benefits are that you can style it to your own taste with a little CSS and caching the JSON file will not add extra load on the Twitter API. Checkout WOW-Multi-Twitter 2.0 For WordPress users you should use WordPress – Display your Cached Tweets using PHP and OAuth or my new plugin.
- You should already have a consumer key, consumer secret, access token and access token secret.
If not please go to https://www.worldoweb.co.uk/2012/create-a-twitter-app-for-the-new-api for a little guide into creating the Twitter App required for this tutorial.
- PHP Server with CURL – I have tested it using PHP 5.3+
- A little knowledge of PHP and CSS are beneficial but not essential.
- This tutorial uses the tmhOAth script by Matt Harris, included in the source files.
Download the Source Files
Last Updated: 23rd August 2013
Download the source files from below:
Unzip and copy the folder tweets and all it’s contents to your server.
tmhOAuth.php is a PHP authentication script to allow you to make a secure call to the twitter API.
cacert.pem enables you to access the twitter API using SSL. You can also download a copy from the following: https://curl.haxx.se/ca/cacert.pem
Adding Keys and Tokens
Once you have copied the files to your server I suggest that you test the installation before deploying it on your live website. Open up keys.php in the includes folder. Add your consumer key, consumer secret, user token and user secret. You can also change the settings for displaying retweets and exclude replies if you wish. Please note that replies and retweets are filtered from the maximum tweets that are set. If you have lots of retweets and replies set max_tweets to a higher amount, unfortunately this is due to the Twitter API and not this script! Save and close.
Calling the function
Now open index.php in the tweets folder and add your twitter username to Line 29 in place of twitter-id. Save and close.
include 'twitter/display-tweets.php';//Include the display-tweets file- Ensure that you have the correct path
display_tweets('twitter-id');//Function to display your tweets
Navigate to index.php in the tweets folder with your browser and you should see your latest twitter posts. Now you can change the parameters in the display_tweets(); function to suit your requirements.
The display_tweets function takes 4 parameters, examples below.
(String) Required Your Twitter screen name (username)
(String) Optional Displays the date or time since format. Leave string empty if not wanting to use a date.
The arguments are:
- ‘eng_suff’ – Displays 6th November
- ‘ddmm’ – Displays 06 Nov
- ‘ddmmyy’ – Displays 06 Nov 2012
- ‘full_date’ – Displays Tues 06 Nov 2012
- ‘time_since’ – Displays the time since the tweet in hours, minutes etc.
- ‘default’ – Displays November 06 2012
(int) Optional How many tweets you want to display. The default is 10.
(int) Optional How often you want to fetch the tweets, in minutes from the Twitter API. The default is 60 minutes.
The default will display your latest 10 tweets at 60 minute intervals with no style.
To display 50 tweets at 20 minute intervals using the time since style.
Styling our Tweets
There are 4 stylesheets enclosed, 3 of which are different themes and 1 is a HTML5/CSS reset. Feel free to roll your own or use any of the themes as a guide.
If you are pretty new to PHP then you may want to stick with the defaults then use it as a basis to learn. If you have any problems or recommendations or tweaks I would love to hear them.
