$ cat demo.php
<html>

<br />
<input type="submit" name="submit" value="Submit" />
</form>
<p>
<?php
if(isset($_POST['submit'])) {
if ($_FILES["file"]["error"] > 0) {
echo "Error: " . $_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 "Stored in: " . $_FILES["file"]["tmp_name"];

}
?>

$ cat demo.php
