Answer 1

If your data still in Blob, you need to encode your data using base64_encode().
Please try it
<object data="data:application/pdf;base64,<?php echo base64_encode(content) ?>" type="application/pdf" style="height:200px;width:60%"></object>

I hope the following will do exactly what you want:
header('Content-type: application/pdf');
header('Content-Disposition: inline; filename=name.pdf');
header('Content-Transfer-Encoding: binary');
header('Accept-Ranges: bytes');
#readfile("data:application/pdf;base64,$content");

I know this thread is old but I recently had a similar issue to solve and wrote this quick guide to cover it.

Basically Depending on if you addslashes or not when inputing the pdf into the database you can view it by the following
I had this in my controller and passed the info to a php page. Setting the headers and if you addslashes make sure to stripslashes otherwise you will just end up with the raw data or blank screen.
$content = stripslashes($text["file"]);
header('Content-type: application/pdf');
header('Content-Disposition: inline; filename=document.pdf');
header('Content-Transfer-Encoding: binary');
header('Accept-Ranges: bytes');
$this->load->view("administrator/load_pdf", [
"title"=>"Display PDF",
"pdf"=>$content,
]);
This is from the php page.
<object data="data:application/pdf;base64,<?php echo base64_encode($content);?>" type="application/pdf" height="100%" width="100%"></object>
