I think you may be doing something wrong. It works for me. Or maybe I
don't understand your question. Here's what I tested:
<?php
$t = array(
array( 'a1', 'b1' ),
array( 'a2', 'b2' )
);

foreach( $t as $i => $v )
var_dump( $v );
?>

And here's what I get:
array(2) {
[0]=>
string(2) "a1"
[1]=>
string(2) "b1"
}
array(2) {
[0]=>
string(2) "a2"
[1]=>
string(2) "b2"
}

Is this test similar to yours?
