Viewer does not show pdf file

I am trying to show a pdf file in a viewer of sort to show the contents of the pdf. however the viewer outputs blank.

the file is located (uploaded) via a folder named 'pdf'

this is my href code to pass which pdf should be shown

<a href="viewimage.php?docnamepath='<?php echo $scannedfilepath; ?>'" class="btn btn btn-success btn-sm"  
                                        name="btnview"
                                        id="btnview"><i class="fa-solid fa-thin fa-envelope fa-xs;"></i> View PDF </a>

this is what it looks like in the url

http://localhost/recordsmanagement/viewimage.php?docnamepath='pdf/FAQs on RA11210 and the IRR.pdf'

this is how I read the pdf

<?php

if(!isset($_SESSION)) {
session_start();
}

if(!isset($_GET['docnamepath'])) {
  $docnamepath=$_GET['docnamepath'];
}



if(isset($_GET['docnamepath'])){

  /** separate name and dir */
  $str_arr = explode ("/",$_GET['docnamepath']);

  $content = $str_arr[0];
  $dir = "pdf/";



// Store the file name into variable
$file = $dir . $content;
$filename = $content;



// Header content type
header('Content-type: application/pdf');

header('Content-Disposition: inline; filename="' . $filename . '"');

header('Content-Transfer-Encoding: binary');

header('Accept-Ranges: bytes');

// Read the file
@readfile($file);

}

?>

the output looks like this. It is blank, what could be causing this

enter image description here

I got the idea by reading this example

I have already tried attaching the file in an email via php the pdf seems fine when sent via email so why is my pdf viewer not showing the pdf

UPDATE:

I have looked into @KD's comment and tried to use a file with no spaces

no spaces

still does not work on my end

as per KJ's comment I checked this link which is about how to get filename to get full path

and I recently discovered (I am a beginner in php) about the basename function

as shown in the answers in the link

$filename = basename($path);

instead of using this:

/** separate name and dir */
$str_arr = explode ("/",$_GET['docnamepath']);

$content = $str_arr[0];
$dir = "pdf/";
  
// Store the file name into variable
$file = $dir . $content;
$filename =  $content;

I changed the code to this:

// Store the file name into variable
$file = $_GET['docnamepath'];
$filename =  basename($path);

it shortened my code and now my pdf viewer is working.
