Android app doesnt send picture to database PHP MYSQL - php

Question

I have a problem, because the picture isnt sent to my database. I used different PHP file which doesnt decode picture again and everything works fine, all results appear in my database, but when I try to connect to that file it doesnt work. This is the php that doesnt work properly:
<?php
header('Content-type : bitmap; charset=utf-8');
if(isset($_POST["encoded_string"])){
$username = $_POST["username"];
$description = $_POST["description"];
$encoded_string = $_POST["encoded_string"];
$decoded_string = base64_decode($encoded_string);
$path = 'place on server where I want pictures to be sent' ;
$file = fopen($path, 'wb');
$is_written = fwrite($file, $decoded_string);
fclose($file);
if($is_written > 0){
$con = mysqli_connect("localhost", "xx", "xx", "xx");
$query = "INSERT INTO meals(username, description, image) values('$username', '$description' , '$path');";
$result = mysqli_query($con, $query);
if($result){
echo "success";
}else{
echo "failed";
}
mysqli_close($con);
}
}
?>
And that one send details properly but not in the way I would like to:
<?php
$con = mysqli_connect("localhost", "xx", "xx", "xx");
$username = $_POST["username"];
$description = $_POST["description"];
$encoded_string = $_POST["encoded_string"];
$statement = mysqli_prepare($con, "INSERT INTO images (username, description, image)
VALUES (?, ?, ?)");
mysqli_stmt_bind_param($statement, "sss", $username, $description, $encoded_string);
mysqli_stmt_execute($statement);
$response = array();
$response["success"] = true;
echo json_encode($response);
?>
Is it casued beacause I have to change FTP settings?
the second code passes all data to database but image is in base64 format so there are plenty characters and it runs slowly. What I want to do is to be able to use the first code, but it doesn't decodes base64 to actual image I am sending and it shows no result in database nor folder in server.

Try this:
$encoded_string = $_POST["encoded_string"];
$path="uploads"."/".rand()."_".time().".jpeg"; //uploads is folder, file name is composed of random number+underscore+time.jpeg
$upload_url="http://xxx.xx.xx.xx/".$path;
if(file_put_contents($path,base64_decode($encoded_string))){
//file uploaded, insert $upload_url into database(Type varchar)
}else{
//echo "file could not uploaded";
}
