Are there alternative methods or libraries in PHP that can be used to convert PDF files to text more effectively?

Converting PDF files to text in PHP can be challenging, especially if the PDF contains complex formatting or images. One alternative method is to use external libraries like `pdftotext` or `poppler-utils` through shell commands to extract text from the PDF more effectively. These libraries are powerful tools for text extraction and can handle a wide range of PDF formats. 

// Using shell command to extract text from PDF using pdftotext
$pdfFile = 'sample.pdf';
$outputFile = 'output.txt';

// Execute pdftotext command to convert PDF to text
shell_exec("pdftotext $pdfFile $outputFile");

// Read the extracted text from the output file
$text = file_get_contents($outputFile);

// Output the extracted text
echo $text;
