Read pdf files with php
Can you read PDF files by using PHP code?
Yes, you can. Either install a command line script that can convert PDFs to text and execute this in PHP
$content = shell_exec('/usr/local/bin/pdftotext '.$filename.' -'); //dash at the end to output content

$content = shell_exec('/usr/local/bin/pdftotext '.$filename.' -'); //dash at the end to output content
