for loop with update query?

[wizardry]

i think i need to have a for loop with this update query but i have not used a for loop with an update query before. can you show me an example ?

<?php

$fooArray = explode(',',$_SESSION['foo_string_id']);

$count_size = count($fooArray);

$t = 0;

while ($t < $size) {

						// the data table
  					 $Foo0 =  GetSQLValueString(isset($_POST['Foo']) ? "true" : "", "defined","'Y'","'N'")[$t];
					 $FooDefault0 =  GetSQLValueString(isset($_POST['FooDefault']) ? "true" : "", "defined","'Y'","'N'")[$t];
					 $FooSize0 =  GetSQLValueString($_POST['FooSize'], "int")[$t];
foreach( $fooArray as $fooId ) {
 
$update = sprintf("UPDATE footable SET `Foo`='$Foo0', FooDefault='$FooDefault0', FooSize='$FooSize0' WHERE FooId=$fooId");

mysql_select_db($database_foo, $Foo);
  $Result = mysql_query($update, $Foo); // or die(mysql_error());



	} // end of query
} // end of while loop

?>

thanks in advance for your help!
