An image upload Situation

[npsari]

I am using this upload file script:

<? 
// Where the file is going to be placed 

$target_path = "images/"; 

/* Add the original filename to our target path. Result is "uploads/filename.extension" */ 

$target_path = $target_path . basename( $_FILES['Image1']['name']); 
$_FILES['Image1']['tmp_name'];  

$target_path = "images/"; 

$target_path = $target_path . basename( $_FILES['Image1']['name']); 

if(move_uploaded_file($_FILES['Image1']['tmp_name'], $target_path)) { 

    echo "The file ".  basename( $_FILES['Image1']['name'])." has been uploaded"; 

} else{ 

    echo "There was an error uploading the file, please try again!"; 
} 

?>

But everytime someone uploads the same image name, the image is over-written.

So this is a little problem because users might upload same image names

How can i prevent the script from overwritting old images

$target_path = "images/"; 
if (file_exists($targetpath)) {
$target_path = $target_path . "a" . basename( $_FILES['Image1']['name']); 
} else {
$target_path = $target_path . basename( $_FILES['Image1']['name']);
}
if(move_uploaded_file($_FILES['Image1']['tmp_name'], $target_path)) { 

    echo "The file ".  basename( $_FILES['Image1']['name'])." has been uploaded"; 
rand()
} else{ 

    echo "There was an error uploading the file, please try again!"; 
} 

?>

Changes in red.

Adds an "a" infront of the filename, so if you want to upload file.jpg and it already exists, you have afile.jpg
