如何在Mac上的PHP中设置Content-type？

Question

I've the problem. Here is my code of php:

include "connection.php";

$patternJPG = '/.pdf$/i';
$gfs = $db->getGridFS();
$collection=$db->Children;
$selected = array('_id'=> new MongoId($_GET['id']));
$cursor=$collection->find($selected);
foreach($cursor as $b){
        $id1 = $b["photoID"];

        $criteria = array("_id" => New MongoId ($id1));
        $nameOriginal = $gfs->findOne($criteria)->file['filename'];
        if(preg_match($patternJPG, $nameOriginal)){
        $row = $gfs->findOne($criteria)->getBytes();
        $mimeType = 'Content-type: application/pdf';
        header("Content-Length: " . strlen($row)); 
        header($mimeType); 
        ob_end_clean(); 
        flush();
        echo($row);
        }

        }

This code literally works on windows platform. When I try to run that code on mac, it doesn't work. I think that code should be worked on all platform instead. Becase all this time, I never have found the problem like this. I have the code that working on windows, that code also work on mac. Please someone help me for fixing this issue.

Well, Chrome is meant to be a basic browser that is customizable to your needs with extensions. Our Web App Store features a bunch of free, handy dandy extensions that will let you view PDFs right in your browser.

Please try to install a plugin to view the PDF files in chrome on MacOS

Also, one way to make sure you have your server side code correct is to save the output as a file with .pdf extension and try to open it to make sure it is a correct PDF.

If it is required to force Chrome to download the file instead of viewing it so the file can be viewed by the system PDF viewer. You can use the header Content-Disposition: attachment as per this question .
