Paypal DoCapture batch process loop - loops

Question

I am trying to implement a batch process for the doCapture API from paypal. I have the code below and it only processes the first record of the database...Help!!
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
<?php
include("xxxxx.php");<---- this is just the database connection
$query2="SELECT *
FROM x where payment_status = 'Pending'";
// WHERE custom IN (
// SELECT custom
// FROM x
// GROUP BY custom
// HAVING count(custom) > 1
// )
//ORDER BY custom";
$results=mysql_query($query2);
$row2 = mysql_fetch_array($results);
$row_count=mysql_num_rows($results);
echo $row_count;
//$auth=$row2['auth_id'];
//while($row2 =mysql_fetch_array($results)){
$arrSize=sizeof($row_count);
for ($number = 0; $number < $arrSize; $number++) {
//for($i=0; $i<$row_count; $i++){
echo $row2['auth_id']; // prints hello
//echo $row2['auth_id'];
/** DoCapture NVP example; last modified 08MAY23.
*
* Capture a payment.
*/
$environment = 'sandbox'; // or 'beta-sandbox' or 'live'

You're only fetching one row out of the database, because your $row2 = mysql_fetch_array($results); line is outside of your for loop. Essentially, you're trying to capture the same payment over and over again, and I'm willing to bet that only the first one is succeeding. Move the fetch statement to just inside the for loop.
