Reading PDF metadata in PHP

The Zend framework includes Zend_Pdf, which makes this really easy:

$pdf = Zend_Pdf::load($pdfPath);

echo $pdf->properties['Title'] . "\n";
echo $pdf->properties['Author'] . "\n";

Limitations: Works only on files without encryption smaller then 16MB.

PDF Parser does exactly what you want and it's pretty straightforward to use:

$parser = new \Smalot\PdfParser\Parser();
$pdf    = $parser->parseFile('document.pdf');
$text   = $pdf->getDetails();

You can try it in the demo page.
