In php5.1.6, RECURSION occurs. Please!

In php5.1.6, RECURSION occurs. Excuse me !!! & Lt ;? Php $ m & nbsp ;=& nbsp; array ('1'); $ m ['A'] & nbsp ;=& nbsp; $ m; print_r ($ m ); die ;? & Gt; this is a simple test. The output result is Array & nbs php5.1.6, and RECURSION appears. Excuse me !!!
$ M = array ('1 ');
$ M ['A'] = $ m;
Print_r ($ m );
Die;
?>

This is a simple test. The output result is
Array ([0] => 1 [a] => Array * RECURSION *)

But the result I want is:
Array ([0] => 1 [a] => Array ([0] => 1 ))

Where should I change it? Please answer and share with us: More
