Twitter PHP API to get Trending Hashtags from a specific city

Recently, we developed a bot to tweet the articles published on Isrg Knowledge base to Twitter automatically after a specific and defined period of time. The bot has ability not only to post the tweets on the Twitter after fetching the entries from the database, but also to convert the tags of the post into hashtag. It was doing pretty well, but I was not satisfied as I wanted to include the trending hashtags from the Twitter into my Tweets, but there are hardly any documentations or tutorial to get the trending hashtags from Twitter so, I’d decided to write my own code which I’ve shared in this blog post to help you out in getting the trending hashtags from the Twitter using PHP API.

Prerequisite

  • Basic Knowledge of PHP
  • Knowledge of JSON and Arrays
  • Twitter Consumer Key and Consumer Secret
  • Twitteroauth PHP library

Getting started

  1. Download the twitteroauth PHP library from the GitHub
  2. Extract the downloaded zip file of twitteroauth PHP library and rename the folder to twitteroauth
  3. Create a PHP file with the name of your choice (Example: hashtag.php) and paste the below code in your PHP file

OUTPUT: #PhirSeModiSarkar #INvsAUS #Chhindwara #Amritsar #NirankariBhawan

  3. Click on the “keys and access tokens” tab on your applications page
  4. Note down the Consumer Key and Consumer Secret (You can generate the Consumer Key/Secret if you’ve not generated it).
  5. Open your PHP file in which you’ve pasted the above PHP code and replace the following contents:

  1. Save the file and run it

Customizing the hashtags

You can increase or decrease the numbers of hashtags you want by changing the value of $NumberOfTags to the desired numbers.
