    <p>To simplify this posed question, assume that each cell has a Row Name and a Column name that properly maps you to the appropriate cell. I'm looping through DB records and creating a location for certain fields in a 2D array that I'll be returning to the caller. My question is how can I tell if a cell already exists at array[rownName][colName]?</p> <p>Here's a high level view of what I'm attempting to do: </p> <pre><code> //While there are more records: while ($row = mysql_fetch_assoc($result)) { //If this key doeesn't already exist in the return array, //add this key/value pair. //Proper logic for determining whether or not a cell has already been //created for this record would go here... $ret[$row['output_row_id']][$row['output_name']] = $row['output_value']; } </code></pre> <p>Thanks in advance for all of your help SO!</p>

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.
