Using php-ai/php-ml with php

I am using notepad++. I have installed composer and from command line I have tried to install the php-ai/php-ml using the following line of code composer require php-ai/php-ml. My cmd tells me that this is successfully installed and everything seems okay.

However, in my index.php file if I try to use any of the libraries in the package php-ai/php-ml for example: use Phpml\Dataset\CsvDataset; I get the following error:

Fatal error: Uncaught Error: Class 'Phpml\Dataset\CsvDataset' not found in C:\xampp\htdocs\test\index.php:5 Stack trace: #0 {main} thrown in C:\xampp\htdocs\test\index.php on line 5

Line 5 is the line which i request to use the library. Do i have to import these libraries or anything?

Solution

  • Composer files are dependecies for the project, so what you should do is:

    1. Move the composer.json and composer.lock file to the same folder as your index.php.
    2. Open a command line window, go to that folder and run: "composer install". That will create the "vendor" folder, download all dependencies and create an autoload.php in your project folder.
    3. Now you can put require __DIR__ . '/vendor/autoload.php' in the top of your index.php
