What are some common challenges when trying to extract data from a PDF file using PHP?

One common challenge when extracting data from a PDF file using PHP is that PDF files are not easily parseable like plain text files. To overcome this, you can use a library like "pdftotext" or "PDFParser" to extract text content from the PDF file. 

// Using pdftotext library to extract text from a PDF file
$pdfFile = 'example.pdf';
$text = shell_exec("pdftotext $pdfFile -");
echo $text;
