i want to make the filename uniqe

[bvilleit]

ok i have an upload script that starts with a normal form then nxt page is this upload script

<?
if(isset( $Submit ))
{
//If the Submitbutton was pressed do:

copy ($FILES['imagefile']['tmp_name'], "files/".$FILES['imagefile']['name'])
or die ("Could not copy");

echo "";
echo "Copy Done....";
echo"<br>$imagefile_name";
echo "<img src='/files/$imagefile_name'> ";
}

else {
echo "";
echo "Could Not Copy, Wrong Filetype (".$_FILES['imagefile']['name'].")";

}

?>

and finally i have s cript that creats a random number

srand((double)microtime()*1000000);
$unique_str = md5(rand(0,9999999));
print $unique_str;

how do i make it change the filename to the filename+the number+the filetype

<?php

if(isset( $Submit )) 
{ 
	//If the Submitbutton was pressed do: 

srand((double)microtime()*1000000); 
$unique_str = md5(rand(0,9999999)); 
print $unique_str;

// This code will grab everything before and after the last dot and turn
// it into the new filename.
$old_name = $_FILES['imagefile']['name'];
$p = strrpos( $old_name , "." );
$new_name = substr( $old_name , 0 , $p ) . $unique_str . substr( $old_name , $p , ( strlen( $old_name ) - $p ) );

copy( $_FILES['imagefile']['tmp_name'] , "files/".$new_name ) or die( "Could not copy" ); 

echo ""; 
echo "Copy Done...."; 
echo"<br>$imagefile_name"; 
echo "<img src='/files/$imagefile_name'> "; 
} 
else
{ 
	echo ""; 
	echo "Could Not Copy, Wrong Filetype (".$_FILES['imagefile']['name'].")"; 
}

?>

if i substitute
$new_name with $imagefile_name would it still work since $imagefile_name is predefined by php as the uploaded files name

the reson i ask is i have 3 pages of code and i use this code 3 times on my website and it would make it much simpler to only modify one page of code each time

You shouldn't have to change anything in my code. I copied the name ( $_FILES[ "imagefile" ][ "name" ] ) and then modified it a little...

oh its not a problem with your code
its just on my script i have it send the $imagefile_name to a db so thats why i was wondering

Oh, ok. Well, then you could change $new_name to $imagefile_name.
