Coping with the arrays having different numbers of members needs something like this (not tested):- <pre><code><?php usort($DAs, "cmpDA"); usort($CAs, "cmpCA"); $DaAccount = 0; $CaAccount = 0; $DaKey = 0; $CaKey = 0; while($DaAccount < 999999 OR $CaAccount < 999999) { switch true { case $DAs[$DaKey]['DebitAccount'] == $CAs[$CaKey]['CreditAccount'] : echo "Account number is ".$DAs[$DaKey]['DebitAccount'].", Value is ".($CAs[$CaKey]['SUM(j.Amount)'] - $DAs[$DaKey]['SUM(j.Amount)'])." (".$CAs[$CaKey]['SUM(j.Amount)']." - ".$DAs[$DaKey]['SUM(j.Amount)'].") "; $DaKey = (($DaKey < count($DAs)) ? $DaKey + 1 : 999999); $CaKey = (($CaKey < count($DAs)) ? $CaKey + 1 : 999999); break; case $DAs[$DaKey]['DebitAccount'] < $CAs[$CaKey]['CreditAccount'] : echo "Account number is ".$DAs[$DaKey]['DebitAccount'].", Value is ".(0 - $DAs[$DaKey]['SUM(j.Amount)'])." (0 - ".$DAs[$DaKey]['SUM(j.Amount)'].") "; $DaKey = (($DaKey < count($DAs)) ? $DaKey + 1 : 999999); break; case $DAs[$DaKey]['DebitAccount'] > $CAs[$CaKey]['CreditAccount'] : echo "Account number is ".$CAs[$CaKey]['CreditAccount'].", Value is ".($CAs[$CaKey]['SUM(j.Amount)'] - 0)." (".$CAs[$CaKey]['SUM(j.Amount)']." - 0) "; $CaKey = (($CaKey < count($DAs)) ? $CaKey + 1 : 999999); break; } } function cmpDA($a, $b) { return (($a['DebitAccount'] == $b['DebitAccount']) ? 0 : (($a['DebitAccount'] < $b['DebitAccount']) ? -1 : 1) ); } function cmpCA($a, $b) { return (($a['CreditAccount'] == $b['CreditAccount']) ? 0 : (($a['CreditAccount'] < $b['CreditAccount']) ? -1 : 1) ); } ?> </code></pre> Sort the 2 arrays into the same key order. The do a while loop, while either array key isn't maxed out. When there keys match you can do the calculation. When one is bigger than the other then there is no matching record for the other so put it out an increment the array key to the other array. If it is the end of the array set the array key to something silly and large. Eventually both arrays will be completed and both keys set to something high. However if the data is stored on a database then it is likely to be FAR quicker and easier to do this in SQL.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
