Compare file names on upload

[dniezby]

I use this code to read information from a flash file that uploads files to my server.

$target_path = "uploads/";
$target_path = $target_path . basename( $_FILES['Filedata']['name']); 

if(move_uploaded_file($_FILES['Filedata']['tmp_name'], $target_path)) 
{
     echo "The file ". basename( $_FILES['Filedata']['name']). " has been uploaded";
} 
else
{
     echo "There was an error uploading the file, please try again!";
}

What would I have to do to have it check to see if a file already on the server exists so it doesn't get overwritten?

if(file_exists($target_path))
{
   // it already exists, so don't do it
}
else
{
   // go ahead an move the file
}

So something like this should work....Or is my syntax off?

$target_path = "uploads/";
$target_path = $target_path . basename( $_FILES['Filedata']['name']); 

if(file_exists($target_path)) {
		echo "Same name error. Please rename file";
	}else{
		if(move_uploaded_file($_FILES['Filedata']['tmp_name'], $target_path)) 
			{
			echo "The file ". basename( $_FILES['Filedata']['name']). " has been uploaded";
		}else{
			echo "There was an error uploading the file, please try again!";
			}
	}
