FileHolder aşağıdaki özeliklere sahip olan adında bir mysql tablo 1.create;

2.id, dosya

HTML aşağıdaki formu kullanarak oluşturmak 3.then

<form enctype="multipart/form-data" action="upload.php" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="1000000" />
<input type="file" required name="uploaded_file">
<input type=submit value=upload >
</form>

4.then Aşağıdaki kodu kullanarak bir upload.php oluşturmak

if ((!empty($_FILES["uploaded_file"])) && ($_FILES['uploaded_file']['error'] == 0)) {
//Check if the file is JPEG image and it's size is less than 350Kb
$filename = basename($_FILES['uploaded_file']['name']);
$ext = substr($filename, strrpos($filename, '.') + 1);
if (($ext == "pdf") && ($_FILES["uploaded_file"]["type"] == "application/pdf") &&
($_FILES["uploaded_file"]["size"] < 350000000)) {
 //Determine the path to which we want to save this file
 $newname = dirname(__FILE__) . '\\Abstract\\' . $filename;
    //Check if the file with the same name is already exists on the server
    if (!file_exists($newname)) {
        //Attempt to move the uploaded file to it's new place
        if ((move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $newname))) {
            echo "It's done! The file has been saved as: " . $newname;
        } else {
            echo "Error: A problem occurred during file upload!";
        }
    } else {
        echo "Error: File " . $_FILES["uploaded_file"]["name"] . " already exists";
    }
} else {
    echo "Error: Only .pdf images under 350MB are accepted for upload";
}
} else {
echo "Error: No file uploaded";
}

//======================================================== the above code is responsible for putting the file in a directory called abstract.

Sonunda biz bir tarayıcıda dosyasını görüntülemek gerekir. Aşağıdakiler

query in a view.php file

/ / Eğer bağlantınız varsa ve db seçin varsayarak

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

select filename from fileHolder where id = 1;

if (empty($filename) && !empty($_GET['filename'])) /*file name comes from a link called 
$filename = $_GET['filename'];                     view which is used to identify the 
                                                    exact file that we are lookingfor*/
$filenames = "..\\user\\Abstract\\".$filename."";
$file = fopen($filenames, "r");

enter code here$fread = fread($file, filesize($filenames)); echo $fread;
