Thanks for all of the help. The tips I got pointed me in the right direction. Once I changed my foreach loops to while (list($key, $value) = each($patient['Visit'])) and while (list($key, $value) = each($patient['M5Symptoms'])) respectively, my data appeared. I figured this out once I realized the foreach() operates on a copy of the array and list($key, $value) = each($array) doesn't.
