图像从Android到MySQL Blob

Question

Good day everybody! As the title say, I try to load an Image from an ImageView to MySQL. I want to save it like a Blob in MySQL.

I have seen several questions about this but no answers in my case: I still remain stuck!

Following is my XML ImageView:

<ImageView
                    android:id="@+id/das_photoib"
                    android:layout_width="150dp"
                    android:layout_height="150dp"
                    android:maxWidth = "150dp"
                    android:maxHeight="150dp"
                    android:layout_gravity="center_horizontal"/>

Following is my JAVA activity

rootView = inflater.inflate(R.layout.devenirassistant, container, false);
photoprofil = (ImageView) rootView.findViewById(R.id.das_photoib);

In the same activity, when I want to upload the picture, I put it in a ContentValues:

ContentValues cv = new ContentValues();
Bitmap bitmap = ((BitmapDrawable)photoprofil.getDrawable()).getBitmap();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
                        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] b = baos.toByteArray();
cv.put("image", Arrays.toString(b));

Then I call an AsyncTask which call a php file itself with the contentValues as parameter. In the php file I get the "image" data and I try to load it in the MySQL "image" row of a table "image_personne", which has been define as "BLOB". I do it like this:

    if (isset($_POST['image'])){
                $image = imagecreatefromstring(base64_decode($_POST['image']));

                $request5 = "INSERT INTO image_personne (id_personne, isDeleted, image, isModere) VALUES ({$_POST['id']}, '0', $image, 0)";

$result5 = mysqli_query($connexion,$request5) or die(mysqli_error($connexion));
            }

There are no errors out, but that doesn't load! Could you help me to debug? Thank you!

This, is what is done now:

Android side:

ContentValues cv = new ContentValues();
Bitmap bitmap = ((BitmapDrawable)photoprofil.getDrawable()).getBitmap();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
                        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] b = baos.toByteArray();
cv.put("image", Base64.encode(b,Base64.DEFAULT));

Php side:

$request5 = "INSERT INTO image_personne (id_personne, isDeleted, image, isModere) VALUES (?,?,?,?)";

            $image = $_POST['image'];
            $id = $_POST['id'];
            $del = '0';
            $mod = '0';
            $stmt = $connexion->prepare($request5); //prepare the statements
            $stmt->bind_param("isbi", $id, $del, $null, $mod ); //bind parameter
            $stmt->send_long_data(0, $image);   //add blob data to statement
            $stmt->execute();

This will work,save it as byte[] array not as Array.toString()

ContentValues cv = new ContentValues();
Bitmap bitmap = ((BitmapDrawable)photoprofil.getDrawable()).getBitmap();
ByteArrayOutputStream baos = new ByteArrayOutputStream();
                        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
byte[] b = baos.toByteArray();
cv.put("image", b);
