[RESOLVED] Renaming uploaded file?

[gszauer]

<?php
foreach ($_FILES["pictures"]["error"] as $key => $error) {
   if ($error == UPLOAD_ERR_OK) {
       $tmp_name = $_FILES["pictures"]["tmp_name"][$key];
       $name = $_FILES["pictures"]["name"][$key];
       move_uploaded_file($tmp_name, "data/$name");
   }
}
?>

As you might have guessed from the code, i am uploading multiple files all the fields are

<input name="pictures[]" type="file" id="pictures[]" />

Now, my php code uploads the files names exactly as they are.
I am soon putting a variable in there called id, and what i need is for the uploaded files to be renamed so it is first the id,an underscore, then a number, ranging from 0 to 11 (i have 11 fields)
A sample of the name would look like
0_0.jpg
0_1.jpg
0_2.jpg
0_3.jpg
ect...
Is it possible to do this without using the rename function, or what would be the easyest way to achive this?
Thank you for your time

prefix the number, don't try and squeeze it in.

e.g.
1_0.jpg
2_0.jpg
3_0.jpg
4_0.jpg

when you are about to move the file, do a file_exists() and see if one is aleady there. If so, start a counter at 1, prefix to the original name, then loop using file_exists until you find a name which works. Then save/rename/move it.

<?php
$server = "localhost";
$user = "program_program";  

$pass = "program";
$database = "program_program";
$tableName = "db_x";
$conn = @mysql_connect($server,$user,$pass); 
$database = @mysql_select_db($database,$conn); 
$query = @mysql_query("SELECT * FROM $tableName ORDER BY id"); 
$total_rows = @mysql_num_rows($query); 
$counter = 0; 
while($ourData = @mysql_fetch_array($query)){ 
     $id = $ourData["id"]; 
     //$band_url = $ourData["band_url"];
     $counter++; 
echo "$id_";
}
