表单提交后显示$ _FILES ['image']

Question

How do i display the image uploaded after the form has been submitted? After the form is submitted it will be a preview page, so i'm not storing the image type BLOB in MySQLyet. How do i display $_FILES['image']?

<?php
 
if(isset($_POST['submit'])) {
 
 //preview page
 
$info = getimagesize($_FILES['image']['tmp_name']);
$imagetype = $info['mime'];
$tmpname = $_FILES['image']['tmp_name'];
$fp = fopen($tmpname,'r');
$data = fread($fp,filesize($tmpname));
$data = addslashes($data);
fclose($fp);
 
} else {
?>
 
<form enctype="multipart/form-data" action="http://www.example.com/submit" method="POST">
<input type="file" name="image" value="" size="50" />
<input type="submit" name="submit" value="submit" />
</form>
 
<?php
}
 
?>

If you don't want to store the image on the server you can preview like this:

<?php
if (isset($_FILES['image'])) {
    $aExtraInfo = getimagesize($_FILES['image']['tmp_name']);
    $sImage = "data:" . $aExtraInfo["mime"] . ";base64," . base64_encode(file_get_contents($_FILES['image']['tmp_name']));
    echo '<p>The image has been uploaded successfully</p><p>Preview:</p><img src="' . $sImage . '" alt="Your Image" />;
}

But if you want to store it on the server, just store it and show it without changing the page.
