Twitter PHP API to get Trending Hashtags from a specific city

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

Twitter API to fetch hashtag from specific city or country using PHP:

Prerequisite:

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

Getting started

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

<?php
$ConsumerKeyAPIKey="YOUR CONSUMER KEY WILL BE HERE";
$ConsumerSecretAPISecret="YOUR SECRET KEY WILL BE HERE";
$NumberOfTags=5; //keep as minimum as possible
$GeoLocleID="20070458";
require "twitteroauth/autoload.php";
use Abraham\TwitterOAuth\TwitterOAuth;
$connection = new TwitterOAuth($ConsumerKeyAPIKey, $ConsumerSecretAPISecret, $access_token, $access_token_secret);
$statues = $connection->get("trends/place", ["id" => $GeoLocleID]);
$stringgerr="";
$i=1;
foreach($statues as $hash)
{    $inner=$hash->trends;
    foreach($inner as $in)
    {
        
        $value=$in->name;
        
        if (strpos($value, '#') !== false) {
        $value=$value;
        } else {
        $value="#".$value;
        }
        $stringgerr.=str_replace(" ","_",$value)." ";
        
        if($i==$NumberOfTags)
        break;
        $i++;
    }
    if($i==$NumberOfTags)
        break;
}
echo $stringgerr;

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

Generating Twitter Consumer Key (API Key) and Consumer Secret

To Generating Twitter Consumer Key (API Key) and Consumer Secret:

1. Go to https://apps.twitter.com/

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:

<?php
$ConsumerKeyAPIKey="Replace this with your consumer key"; 
$ConsumerSecretAPISecret="Replace this with your consumer secret";

6. Save the file and run it

Customising the hashtags

1. Increasing the numbers of tweets 

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

2. Changing the Geographical locations

You can change the geographical area by changing the value of $GeoLocleID To the desired location, city or country.

3. Changing the format of the hashtag

You can change the composition of the hashtag by altering the value of $stringgerr string the code.
