Since, according to the array above, assign has only one element, and the key to that element is '1', $assign will always be one and this code run through just once. $details is an array with three key/value pairs. They are 'type' => 'Transcript', 'rows' => '603', and 'codeapply' => (an array). > > > foreach ($assign['codeapply'] as $codeapply => $ca_details) > > > { So, looking at this it looks like what you actually want to do is: foreach($details['codeapply'] ... ) $details['codeapply'] has a single key/value pair, which is ('1' => (an array)). This array can be reached by using $ca_details['codeset']... etc. > > > echo "<tr>"; > > > echo "<td>"; > > > echo $details['type']."
