Post Tweet to Twitter Using PHP

Twitter is one of the most popular social media platforms, and integrating Twitter with your PHP application can open up various possibilities like automating posts or fetching tweets. In this tutorial, we’ll learn how to post a tweet using PHP with the Twitter API.

Prerequisites

• Twitter Developer Account: You’ll need a developer account to create an app and get API credentials. Sign up at Twitter Developer Portal.
• Composer Installed: PHP Composer is required to manage dependencies.
• Basic PHP Knowledge: Familiarity with PHP basics and file handling.

Follow this video for complete guidance:

Step 1: Set Up Your Twitter App

• Visit the Twitter Developer Portal.
• Create a new project and an associated app.
• Generate the following credentials under Keys and Tokens: API Key, API Secret Key, Access Token, Access Token Secret
• Save these credentials securely in a file named credentials.json in your project directory.

Step 2: Install TwitterOAuth Library

We’ll use the TwitterOAuth library by Abraham to interact with the Twitter API.

Run the following command in your project directory to install the library via Composer:

composer require abraham/twitteroauth

Step 3: Create the PHP Script

Here’s the PHP script to post a tweet:

<?php
require 'vendor/autoload.php';
use Abraham\TwitterOAuth\TwitterOAuth;

// Load credentials from JSON file
$credentials = json_decode(file_get_contents('credentials.json'));

// Define the tweet message
$message = "Tweet testing";

// Establish a connection to the Twitter API
$connection = new TwitterOAuth(
    $credentials->api_key, 
    $credentials->api_secret, 
    $credentials->access_token, 
    $credentials->access_token_secret
);

// Set API version to v2
$connection->setApiVersion('2');

// Prepare the tweet
$tweet['text'] = $message;

// Send the tweet
$response = $connection->post('tweets', $tweet);

// Check response and output result
if (isset($response->data->id)) {
    echo 'Tweeted successfully';
} else {
    echo 'Error: ' . $response->detail;
}

Troubleshooting

• Ensure your app has the correct permissions (Read and Write).
• Check rate limits in the Twitter Developer Portal.
• Debug the $response object for error details.

With just a few lines of PHP, you can post tweets directly to Twitter using the Twitter API and the TwitterOAuth library. This setup can be extended to handle more complex tasks like scheduling tweets, fetching timelines, or even building a Twitter bot.
