I'm using this library to implement the Nexmo SMS service on my server. I required the library using Composer like so:
"require" : {
"prawnsalad/nexmo": "dev-master"
}
which I found here and followed the instructions included in the README like so:
require 'vendor/autoload.php';
use NexmoMessage;
$phone = '123456789';
$sms = new NexmoMessage(NEXMO_KEY, NEXMO_SECRET);//defined in another file
$sms->sendText($phone, 'from', "yo");//$phone is a valid number in actual case
However I keep getting the error in the title of this question. I see that Composer has imported the library successfully and I see the class and constructor for NexmoMessage, yet for some reason this error keeps happening no matter what I do. I'm not sure if this is due to an issue with the library or with how I'm using Composer. I've never had an issue with Composer in the past so I'm boggled why this is happening here. Thanks
Well, that library states that it supports PSR-4, which means they absolutely MUST use PHP namespaces, but they don't. That last commit 8 months ago https://github.com/prawnsalad/Nexmo-PHP-lib/commit/8e422c4f8f43c52acb70ebd5f9e7c6ff81a1f352 broke the autoloading. And nobody noticed up to today.
You can easily tell by looking at the source code: There is no namespace being used.
Your best action now would be to fix this issue and send a pull request! Github allows to edit files in the browser! Second best action would be to create an issue and let the authors know.
