What are the advantages and disadvantages of using OCR technology in PHP for automating data extraction from PDF files?

Issue: Automating data extraction from PDF files can be a time-consuming task. Using OCR technology in PHP can help streamline this process by converting scanned text into editable and searchable data. However, OCR technology may not always be 100% accurate, leading to potential errors in data extraction. PHP Code Snippet: 

// Include the Tesseract OCR library
require_once 'vendor/autoload.php';

use thiagoalessio\TesseractOCR\TesseractOCR;

// Specify the path to the PDF file
$pdfFilePath = 'path/to/pdf/file.pdf';

// Use Tesseract OCR to extract text from the PDF file
$text = (new TesseractOCR($pdfFilePath))->run();

// Display the extracted text
echo $text;
