    <p>I have an array with "gaps" like this:</p> <pre><code>$arr = array ( "bananas" =&gt; array ( "2010-01-01" =&gt; "10.1", "2010-01-02" =&gt; "11.4", "2010-01-05" =&gt; "13.3", //missing 03, 04 "2010-01-06" =&gt; "09.2", "2010-01-07" =&gt; "11.1" ), "grapes" =&gt; array ( "2011-01-05" =&gt; "20.1", "2011-01-06" =&gt; "21.4", "2011-01-07" =&gt; "23.3", "2011-01-08" =&gt; "29.2", "2011-01-10" =&gt; "21.1", //missing 09 "2011-01-11" =&gt; "21.0" ), "coconuts" =&gt; array ( "2012-01-28" =&gt; "50.1", "2012-01-29" =&gt; "51.4", "2012-02-02" =&gt; "53.3", //missing 30, 31, 01 "2012-02-03" =&gt; "51.1" ) ); </code></pre> <p>I don't know how many products and "date=>price" are there in an array.<br/> How I can fill missing date(s) with last price before gap?</p> <p><strong>Important:</strong> dates can be in different months (look at <code>"coconuts"</code>).</p> <p>I want the result to be like this:</p> <pre><code>$arr = array ( "bananas" =&gt; array ( "2010-01-01" =&gt; "10.1", "2010-01-02" =&gt; "11.4", //was last price before gap "2010-01-03" =&gt; "11.4", //filling missing "2010-01-04" =&gt; "11.4", //filling missing "2010-01-05" =&gt; "13.3", "2010-01-06" =&gt; "09.2", "2010-01-07" =&gt; "11.1" ), "grapes" =&gt; array ( "2011-01-05" =&gt; "20.1", "2011-01-06" =&gt; "21.4", "2011-01-07" =&gt; "23.3", "2011-01-08" =&gt; "29.2", //was last price before gap "2011-01-09" =&gt; "29.2", //filling missing "2011-01-10" =&gt; "21.1", "2011-01-11" =&gt; "21.0" ), "coconuts" =&gt; array ( "2012-01-28" =&gt; "50.1", "2012-01-29" =&gt; "51.4", //was last price before gap "2012-01-30" =&gt; "51.4", //filling missing "2012-01-31" =&gt; "51.4", //filling missing "2012-02-01" =&gt; "51.4", //filling missing "2012-02-02" =&gt; "53.3", "2012-02-03" =&gt; "51.1" ) ); </code></pre> <p>Thank you for your time.</p>

    2. COYou'll have to calculate the differences between the entries. If its more than a day than it is a gap

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.
