syntax for printing multi-dimensional arrays

Hi all I am having problems printing members of an array that has two dimensions and am wondering if someone can help me with the syntax required to do this. If i have the follwing code: <?php $test=array('test1'=>'a','test2'=>'b'); print "$test[test1]"; ?> I get 'a' echoed to the screen as expected. But if i make the array 2 dimensional like this: <?php $test[0]=array('test1'=>'a','test2'=>'b'); print "$test[0][test1]"; ?> I would expect to get 'a' echoed to the screen again but instead i get this: Array[test1]. Has anyone seen this before and can help or point me to some goods docs on it? Thanks in advance for any help Cheers Bob
