How to convert an image to base64 encoding?

Question

Can you please guide me how can I convert an image from a URL to base64 encoding?

Answer 1

Here is the code for upload to encode and save it to the MySQL

if (!isset($_GET["getfile"])) {
    if ($_FILES["file"]["error"] > 0) {
        echo "Error: " . $_FILES["file"]["error"] . "
";
    } else {
        move_uploaded_file($_FILES["file"]["tmp_name"], $_FILES["file"]["name"]);

        $bin_string = file_get_contents($_FILES["file"]["name"]);
        $hex_string = base64_encode($bin_string);
        $mysqli = mysqli_init();

        if (!$mysqli->real_connect('localhost', 'root', '', 'arihant')) {
            die('Connect Error (' . mysqli_connect_errno() . ') ' . mysqli_connect_error());
        }

        $mysqli->query("INSERT INTO upload(image) VALUES ('" . $hex_string . "')");
    }
}

For showing the image use this

echo "";
