    <p><strong>Answer:</strong></p> <p>So my issue turned out to be with the $eventValue and not the key. I was assuming the key was wrapped in brackets when it was added to the $days array but that was not the case. var_export showed me what really gets added to the array.</p> <p>To solve the problem, I removed the enclosing quotes from the $eventValue as well as the trailing , comma.</p> <p><strong>Below is the original question:</strong></p> <p>Apologies as I do not know a whole lot of PHP, but I am trying to achieve something that I hope someone here can help with.</p> <p>I have a loop that is finding specific days of a month to highlight on a calendar. In order for the calendar to highlight a specific day and wrap it in a class as well as a link tag, I need the array to be in this format:</p> <pre><code>$days = array( 2 =&gt; array('/weblog/archive/2004/Jan/02', 'linked-day'), 3 =&gt; array('/weblog/archive/2004/Jan/03', 'linked-day'), 8 =&gt; array('/weblog/archive/2004/Jan/08', 'linked-day'), 22 =&gt; array('/weblog/archive/2004/Jan/22', 'linked-day'), ); </code></pre> <p>Within my loop, I have these two variables:</p> <pre><code>$eventDay = substr("$str", -2, 2); $eventValue = "array('http://example.com', 'linked-day'),"; </code></pre> <p>and at the end of my loop I have this:</p> <pre><code>$days[$eventDay] = $eventValue; </code></pre> <p>The problem is, when I print_r ($days), my $eventDay key is wrapped in [] square brackets and so the day cannot be found by the calendar. I need to find a way to prevent it from being wrapped in brackets.</p> <p>Perhaps I am approaching this all wrong. If someone has some suggestions I would really appreciate it.</p> <p>I am using Keith Devens' PHP Calendar script to do this:</p> <p><a href="http://keithdevens.com/software/php_calendar" rel="nofollow">http://keithdevens.com/software/php_calendar</a></p> <p>Thanks!</p> <p><strong>Full code:</strong></p> <p><a href="http://pastie.org/5503664" rel="nofollow">http://pastie.org/5503664</a></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.
