I have a pdf document and I want to check if a specific text occurs (which are tags that I put in while generating the pdf) in the document, however using these libraries (tcpdfFpdi, pdftk or fdpi) I couldn't figure out if it's possible or how to do it.

$str = "{hello}";

$pdf = new TcpdfFpdi();
$pdf->setSourceFile($filePath);

$pdf->searchForText($str); // something like this which returns boolean

If I try without any library to dd(file_get_contents($filePath)), it returns a very long output and doesn't seem to contain the file I want so I think it's better to use one of those libraries.

Just an idea…

It's no actual PHP solution but you could use tools like pdftotext which I know from this post (where a PDF file is converted into a string to count its words): https://superuser.com/a/221367/535203

You can install it and play around with that command and call it from within your PHP application.

As far as I remember (long time ago since I used pdftotext) the output text is not exaclty the PDF's content but to search a few tags in it it's at least a good try.
