i'm using images sample @ moment finished php should allow display pdf documents. if it's i'm using phpmyadmin , mysqli.

as comments suggest, storing file location in database better storing file's data in database. if need store file contents in database reason, there 2 methods. 1 using html data: url , other having php file middle man.

for php middle man method, @ answer above mine sets header information , echo's file contents. file extension doesn't matter since browsers refer content-type header instead of file extensions.

for data url method, can placed directly in code check out http://en.wikipedia.org/wiki/data_uri_scheme

<?php     // array of valid mime types, prevents possible xss methods.     $valid_mimes = array(         'image/png',         'image/gif',         'image/jpeg'     );      // obtain mime type using finfo     // finfo allows strings instead of file path     $finfo = new finfo(fileinfo_mime_type);     $mime = $finfo->buffer($row['file']);      // check if mime in our $valid_mimes array     if(!in_array($mime,$valid_mimes)) {         // handle error         echo 'illegal mime type: '.$mime;         die();     }      $b64 = base64_encode($row['file']);     echo '<img src="data:'.$mime.';base64,'.$b64.'" />'; ?>
