    <p>These are some issues in your code that affects performance:</p> <ol> <li><p><strong>You should not call <code>print</code> for each row of your table</strong>. That penalizes performance (if the server is not caching the output) as everytime you call <code>print</code> you will be sending bytes across the net which is a costly operation that is better be done <strong>once for one big chunk of data</strong> rather than <strong>many times for small chunks of data</strong> , that is the reason web servers will often cache all your PHP output prior to sending it to the browser.</p></li> <li><p>You should <strong>pass by reference the array value</strong> when traversing the array with foreach, to avoid the copy of a variable in each iteration of the loop.</p></li> <li><p><strong>Echo with commas, not periods</strong>. If you use periods, PHP has to concatenate the string before it outputs. If you use commas, it just outputs them in order with no extra processing.</p></li> <li><p><strong>You should use echo instead of <code>print()</code></strong>. As a language construct rather than a function, echo has a slight performance advantage over print().</p></li> </ol> <p>So this is your code with points 2, 3 and 4 above corrected, thus assuming your web server is caching output:</p> <pre><code>&lt;?php $query = $db-&gt;query('SELECT type FROM card_type'); $rows = $query-&gt;fetchAll(); foreach($rows as &amp;$row) { echo '&lt;option value="', $row['type'] ,'"&gt;' ,$row['type'] , '&lt;/option&gt;'; } ?&gt; </code></pre> <p>and this is your code with point 1 and 2 above corrected, thus assuming your web server is not caching the output:</p> <pre><code>&lt;?php $query = $db-&gt;query('SELECT type FROM card_type'); $rows = $query-&gt;fetchAll(); $out = ''; foreach($rows as &amp;$row) { $out .= '&lt;option value="'.$row['type'].'"&gt;'.$row['type'].'&lt;/option&gt;'; } echo $out; ?&gt; </code></pre>

    1. CO[print is not actually a real function (it is a language construct).](http://php.net/manual/en/function.print.php) I've no idea whether there's a performance difference or not. I'd never seen echo accepting multiple parameters though - have always used concatenate or just exited php and re-entered. `?>SOME HTML HERE<?php` Don't all servers cache output? Surely they aren't sending tiny fragments of code for each echo.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
