How to save converted JPG image from PDF using Imagemagick to database

Question

loading pdf file from php form

                $name = $_FILES['file']['name'];
                $fileName = substr($_FILES['file']['tmp_name'], 5).".".$ext;
                date_default_timezone_set('UTC');
                $fileDate = date('d.m.Y');
                $fileSize = $_FILES['file']['size'];
                $folder = $_POST['folder'];


                $target_dir="$media_dir/";
                $target_file= $target_dir .  basename($_FILES["file"]["name"]);

Move file from tmp to media path

                move_uploaded_file($_FILES['file']['tmp_name'], $target_file);

converting pdf to jpg using Imagick

                $imagick = new imagick();
                $imagick->readImage($target_file);
                $imagick->setImageFormat('jpg');

                $image= basename($target_file,".pdf");

                foreach($imagick as $i=>$imagick) 
                { 

                    $imagick->writeImage($target_dir . $image . ($i+1) ." of ".  $pages.".jpg"); 



                } $imagick->clear();

How can I save the converted image to a database. Currently, it is just uploading the original pdf image to the database.

                $id_object = _addMediaFile($name, $fileName, 2, $fileSize, $folder);



               $ret = array("ID" => $id_object, "name" => $name, "fileName" => $fileName, "fileSize" => $fileSize, "fileDate" => $fileDate, "fileType" => 4, "folder" => $folder);
                echo json_encode($ret);
            }

Consider converting the image directly into a blob that you directly save into a database column of blob type. For instance, with $a = $image->getImageBlob(); you would save $a into the database. Reference: http://php.net/manual/en/imagick.getimageblob.php
