Pulling unique data from database into an array

I am pulling data from a database that list the Language a person speaks and the id number. It is in a format like this. user_id field_value 6 English||Spanish 2 English 8 English||Portuguese||Finnish 5 English||Japanese||German 3 English 1 English 9 German each time it looks at a new record it list all the languages that that person speaks with a double pipe in between each language. What I need to do is find all the unique languages so I can generate a list of languages that do not have any repeats in it with each users id number that speaks that language. so the list above would be 6,2,8,5,3,1 English 8 Portuguese 8 Finnish 5 Japanese 5,9 German 6 Spanish Using the script below (I am using ADODB for a database layer) I am able to pull the data into an array of both fields so it gives me an array that looks like this Array ( [6] => English||Portuguese||Finnish [2] => English||Portuguese||German [8] => English [7] => English ) ) But I can not figure out how to split it up so there is a list like I have above. I know I need to use explode, array_merge and array_unique but I am not sure how to set it up so it will work correctly $sql = "SELECT * FROM default_UserDBElements WHERE field_name = 'Languages'"; $ADODB_FETCH_MODE = ADODB_FETCH_ASSOC; $recordSet = $conn->Execute($sql); if (!$recordSet) print $conn->ErrorMsg(); else while (!$recordSet->EOF) { $array[$recordSet->fields['user_id']] = $recordSet->fields['field_value']; $recordSet->MoveNext(); } print_r($array);
