$text = shell_exec(gs -q -sDEVICE=txtwrite -dBATCH -dNOPAUSE -dFirstPage='.(int)$page_number.' -dLastPage='.(int)($page_number+1).' -sOutputFile=textfilename.txt exemple.pdf');

You don't have a string as a parameter there and you need to escape values before passing them to the command. Finally, you need to specify an output file, in this case you want the data to go to STDOUT for access by PHP.

$first_page = escapeshellarg((int)$page_number);
$last_page = escapeshellarg($page_number + 1);
$text = shell_exec("gs -q -sDEVICE=txtwrite -dBATCH -dNOPAUSE -dFirstPage=$first_page -dLastPage=$last_page -sOutputFile=%stdout exemple.pdf");
