About The Project

With all the uncertainty surrounding the future of X (née Twitter), I decided to take a look at Bluesky, which somewhat ironically has its roots in Twitter, where it was started as an internal project. I worry about Bluesky's long-term, given that ultimately it too has to make money, something that Twitter has singularly failed to do. None of this, of course, affects the topic today, which is posting to Bluesky via the API.

I needed a way to post to Bluesky from PHP and so I searched for a library to help and when I couldn't find one I wrote this.

Getting Started

NOTE This is for v2 of php2Bluesky. If you are looking for the v1 details you can find that here.

Running the script is very straightforward:

1. install composer
2. add the BlueskyAPI

composer.phar require cjrasmussen/bluesky-api

3. add php2Bluesky

composer.phar require williamsdb/php2bluesky

Now you can inspect example.php to get some examples and/or see below.

If you are interested in what is happening under the hood then read this series of blog posts.

Prerequisites

Requirements are very simple, it requires the following:

1. PHP (I tested on v8.1.13) - requires php-dom and php-gd
2. Clark Rasmussen's BlueskyApi (requires v2 or above)
3. a Bluesky account and an Application Password (see this blog post for details of how to do that).

Installation

1. As above

Usage

Here's a few examples to get you started.

Note: connection to the Bluesky API is made via Clark Rasmussen's BlueskyApi which this makes a connection to Bluesky and manages tokens etc. See here for more details.

• Setup and connect to Bluesky:

require __DIR__ . '/vendor/autoload.php';

use williamsdb\php2bluesky\php2Bluesky;

$php2Bluesky = new php2Bluesky();

$handle = 'yourhandle.bsky.social';
$password = 'abcd-efgh-ijkl-mnop';
    
// connect to Bluesky API
$connection = $php2Bluesky->bluesky_connect($handle, $password);

• Sending text with tags

$text = "This is some text with a #hashtag.";

$response = $php2Bluesky->post_to_bluesky($connection, $text);
print_r($response);
if (!isset($response->error)){
    $url = $php2Bluesky->permalink_from_response($response, $handle);
    echo $url.PHP_EOL;            
}

• Uploading a post with a single image and embedded url

$filename1 = 'https://upload.wikimedia.org/wikipedia/en/6/67/Bluesky_User_Profile.png';
$text = 'Screenshot of Bluesky';
$alt = 'This is the screenshot that Wikipedia uses for their https://en.wikipedia.org/wiki/Bluesky entry.';

$response = $php2Bluesky->post_to_bluesky($connection, $text, $filename1, '', $alt);
print_r($response);
if (!isset($response->error)){
    $url = $php2Bluesky->permalink_from_response($response, $handle);
    echo $url.PHP_EOL;            
}

• Uploading a post with multiple images (both local and remote)

$filename1 = 'https://upload.wikimedia.org/wikipedia/en/6/67/Bluesky_User_Profile.png';
$filename2 = '/Users/neilthompson/Development/php2Bluesky/Screenshot1.png';
$filename3 = 'https://www.spokenlikeageek.com/wp-content/uploads/2024/11/2024-11-18-19-28-59.png';
$filename4 = '/Users/neilthompson/Development/php2Bluesky/Screenshot2.png';
$text = 'An example of four images taken both from a local machine and remote locations with some alt tags';
    
// send multiple images with text
$imageArray = array($filename1, $filename2, $filename3, $filename4); 
$alt = array('this has an alt', 'so does this');
    
$response = $php2Bluesky->post_to_bluesky($connection, $text, $imageArray, '', $alt);
print_r($response);
if (!isset($response->error)){
    $url = $php2Bluesky->permalink_from_response($response, $handle);
    echo $url.PHP_EOL;            
}

• Sending parameters when connecting to override defaults

$php2Bluesky = new php2Bluesky($linkCardFallback = 'RANDOM', 
                               $failOverMaxPostSize = FALSE, 
                               $randomImageURL = 'https://picsum.photos/1024/536',
                               $fileUploadDir='/tmp');
