How to search a snippet in a PDF remotely?

Question

Is there a way for me to search an excerpt, or a word in a PDF that’s on the internet? I researched about CURL, some libraries, but found nothing. More or less this way:

I have a website and in it the guy would insert a name for example: John. After that my website script would check inside the file: http://www.bu.ufsc.br/ArtigoCientifico.pdf there is the name John, and I would return to me whether or not there is.

Is there a way to do that? Does anyone know a library or can give me a north?

Answer 1

The library http://www.pdfparser.org/ allows you to pick up text from PDF files.

$url = 'http://www.bu.ufsc.br/ArtigoCientifico.pdf';
$nome = 'João';

$parser = new \Smalot\PdfParser\Parser();

$pdf = $parser->parseContent(file_get_contents($url));
$text = $pdf->getText();

if (strpos($text, $nome) !== false) {
    // achou o nome
}
