help with multidimentional arrays

Hello, What I intend to do is put the database query results in a multidimentional array like this. $sponsor_id['sponsor1'] = ('project1 title', 'project2 title', 'project3 title'); $sponsor_id['sponsor2'] = ('project1 title','project7 title'); .... Here is the code snippet for doing that: == while( ($rec = odbtp_fetch_array($qry)) ) { if (empty($sponsor_id[$rec[1]])) { $sponsor_id[$rec[1]] = array(); } else { array_push($sponsor_id[$rec[1]], $rec[0]); } } == Now, when the following code is used to print the array $sponsor_id, it only prints out the keys of the array which are: sponsor1 sponsor2 Those project titles are not printed out. == foreach ($sponsor_id as $sponsor => $arr) echo "$sponsor:"; foreach ($arr[$sponsor] as $project) { echo "$project<br>"; } == My expected output should be like: sponsor1: project1 title project2 title project3 title sponsor2 project1 title project7 title What is wrong? I'd appreciate any help. Thanks, Bing
