//connect to mysql database
if ($conn = mysqli_connect('localhost', 'root', 'admin', 'test')) {
$content = mysqli_real_escape_string($conn, $content);
$sql = "SELECT type, content FROM images where id = {$imageId}";
if ($rs = mysqli_query($conn, $sql)) {
$imageData = mysqli_fetch_array($rs, MYSQLI_ASSOC);
mysqli_free_result($rs);
} else {
echo "Error: Could not get data from mysql database. Please try again.";
}
//close mysqli connection
mysqli_close($conn);
} else {
echo "Error: Could not connect to mysql database. Please try again.";

$content = mysqli_real_escape_string($conn, $content);
$sql = "insert into images (name, size, type, content) values ('{$name}', '{$size}', '{$type}', '{$content}')";
