OK, so I have the following code that reads a csv file that than outputs the result in the form of a HTML table: <pre><code>$fhdrop = fopen("ac.csv", "r"); while (!feof($fhdrop) ) { $at[] = fgetcsv($fhdrop, 1024); } $fhdrop2 = fopen("rc.csv", "r"); while (!feof($fhdrop2) ) { $at2[] = fgetcsv($fhdrop2, 1024); } ?> <table border=1> <tr> <td>a</td> <td>b</td> <td>c</td> <td>d</td> <tr> <td><?php echo $at[0][0] ?></td> <td><?php echo $at[0][1] ?></td> <td><?php echo number_format($at[0][1]*$at2[0][1],2) ?></td> <td><?php echo number_format($at[0][1]*$at2[1][1],2) ?></td> </tr> <tr> <td><?php echo $at[1][0] ?></td> <td><?php echo $at[1][1] ?></td> <td><?php echo number_format($at[1][1]*$at2[0][1],2) ?></td> <td><?php echo number_format($at[1][1]*$at2[1][1],2) ?></td> </tr> <tr> <td><?php echo $at[2][0] ?></td> <td><?php echo $at[2][1] ?></td> <td><?php echo number_format($at[2][1]*$at2[0][1],2) ?></td> <td><?php echo number_format($at[2][1]*$at2[1][1],2) ?></td> </tr> <tr> <td><?php echo $at[3][0] ?></td> <td><?php echo $at[3][1] ?></td> <td><?php echo number_format($at[3][1]*$at2[0][1],2) ?></td> <td><?php echo number_format($at[3][1]*$at2[1][1],2) ?></td> </code></pre> Wag1 pplz!!! This account is mine now!!! The contents of ac.csv are: <pre><code>a, 5, b, 10, c, 24, d, 21 </code></pre> The contents of rc.csv are: <pre><code>not, 1.87, notatall, 1.78 </code></pre> As you can guess from the original code, in the second to columns I need a multiplication. So for example in the second row, third coloumn I need 5*1.87 and 5*1.78. So basically a*not and a*notatall. My code is not very efficient, how can I make it more efficient? I want all of these (somehow) put into a loop. It needs to have the exact same outcome, due to the complexity and the fact that it has 2d arrays, I have not yet been able to do this!

Guidance

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.
