Unable to display BLOB image with Data URI - php

Question

I have a jpg image stored in MySql Database table in the column with the data type as BLOB that part of the php code works fine.
I am trying to display that image using the below php code but it would not work. I see a small icon on the screen which is definitely not the image ? what's wrong any help?
1) Read the image php file
<?php
header("Content-Type: image/jpg");
$db=mysqli_connect("localhost","root","root123","deal_bank","3306");
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
mysqli_select_db($db,"deal_bank");
$sql = "SELECT * FROM image";
$sth = $db->query($sql);
$result=mysqli_fetch_array($sth);
echo '<img src="data:image/jpg;base64,'.base64_encode( $result['image'] ).'"/>';
?>
2) Upload the file into the MySql Database
<?php
$con=mysqli_connect("localhost","root","root123","deal_bank","3306");
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
mysqli_select_db($con,"deal_bank");
$allowedExts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["file"]["name"]);
$extension = end($temp);
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/jpg")
|| ($_FILES["file"]["type"] == "image/pjpeg")
|| ($_FILES["file"]["type"] == "image/x-png")
|| ($_FILES["file"]["type"] == "image/png"))
&& ($_FILES["file"]["size"] > 20000)
&& in_array($extension, $allowedExts)) {
if ($_FILES["file"]["error"] > 0) {
echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
} else {
echo "Upload: " . $_FILES["file"]["name"] . "<br>";
echo "Type: " . $_FILES["file"]["type"] . "<br>";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";
if (file_exists("upload/" . $_FILES["file"]["name"])) {
echo $_FILES["file"]["name"] . " already exists. ";
} else {
$stmt = $con->prepare('INSERT INTO image (image) VALUES (?)');
$null = null;
$stmt->bind_param('b', $null);
$stmt->send_long_data(0, file_get_contents($_FILES['file']['tmp_name']));
$stmt->execute();
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . $_FILES["file"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
// $image = addslashes(file_get_contents($_FILE['file']['tmp_name']));
//mysqli_query($con,"INSERT INTO image (image) VALUES ('{$image}') ");
}
}
} else {
echo "Invalid file";
}
?>

Answer 1

I replaced
header("Content-Type: image/jpg");
with
ob_start( );
it now works fine i am not sure what was the problem before ?
