Not receiving the image from database PHP LongBlob - php

Question

Hi i'm trying to receive my images from the database. I already can insert the images, but I don't know if it goes wrong overthere or that I do something wrong with getting the image.
The code for inserting the image:
public function Save(){
/*** check if a file was uploaded ***/
if(is_uploaded_file($_FILES['userfile']['tmp_name']) && getimagesize($_FILES['userfile']['tmp_name']) != false)
{
/*** get the image info. ***/
$size = getimagesize($_FILES['userfile']['tmp_name']);
/*** assign our variables ***/
$type = $size['mime'];
$imgfp = fopen($_FILES['userfile']['tmp_name'], 'rb');
$size = $size[3];
$name = $_FILES['userfile']['name'];
$maxsize = 99999999;
/*** check the file is less than the maximum file size ***/
if($_FILES['userfile']['size'] < $maxsize )
{
/*** connect to db ***/
$db = new Db();
/*** our sql query ***/
$sql = "INSERT INTO Foto (image_type ,image, image_size, image_name)
VALUES ('". $type ."',
'". $imgfp ."',
'". $size ."',
'". $name ."');";
$db->conn->query($sql);
$sql = "SELECT * FROM Foto ORDER BY id DESC LIMIT 1;";
$select = $db->conn->query($sql);
$numberofRows = $select->num_rows;
if($numberofRows == 1)
{
while ($oneSelect = $select->fetch_assoc())
{
return $oneSelect;
}
} else {
throw new Exception("Fout");
}
}
else
{
throw new Exception("Bestand is te groot");
}
}
else
{
throw new Exception("Dit extensie is niet ondersteund");
}
}
The code for loading the images:
<?php
include_once("classes/Db.class.php");
//$id = $_GET['id'];
$id = "33";
$db = new Db();
$sql = "SELECT image, image_type FROM Foto WHERE id = '". $id ."';";
$result = $db->conn->query($sql);
$row = $result->fetch_assoc();
if(sizeof($row) == 2)
{
header("Content-type: ".$row['image_type']);
echo $row['image'];
}
else
{
throw new Exception("Out of bounds Error");
}
?>

You're not actually inserting the image data. Read up on the fopen() function, it doesn't return the image data, but a file handle that can then be used for reading from or writing to a file (using, for example, fread() or fwrite()). Easy way out is using file_get_contents().
But take my advice, it's really bad practice to store images in the database. They're files and better off stored on the file system (hence the name). Makes serving them a lot faster too, as no PHP request has to be executed. Store the filename and maybe a relative path to the file in the database instead.
