I've got a PHP code that selects a PDF file and converts it to a text file.

I'm using an external library pdf-to-text with the composer.

Following is the system display error:

Fatal error: Uncaught Error: Class 'Pdf' not found in C:\xampp\htdocs\testcomposer\test2.php:6 Stack trace: #0 {main} thrown in C:\xampp\htdocs\testcomposer\test2.php on line 6

    public function __construct(string $binPath = null)
    {
        $this->binPath = $binPath ?? '/usr/bin/pdftotext';
    }

    public function setPdf(string $pdf) : Pdf
    {
        if (!file_exists($pdf)) {

        }

        $this->pdf = $pdf;

        return $this;

        $process->run();

        if (!$process->isSuccessful()) {
