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>

Answer 2

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");

Answer 3

I know this thread is old but I recently had a similar issue to solve and wrote this quick guide to cover it. https://medium.com/@alexmoran_19787/display-pdf-from-blob-file-11996146dbc0

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>
