    <p>I have tried to get the below code to work for a good couple of hours, but just don't succeed.</p> <p>I have this date array: </p> <pre><code>Array ( [0] =&gt; Array ( [0] =&gt; 2007 ) [1] =&gt; Array ( [0] =&gt; 2008 ) [2] =&gt; Array ( [0] =&gt; 2009 ) ... ) </code></pre> <p>and this plusMinus one:</p> <pre><code>Array ( [0] =&gt; Array ( [plus] =&gt; 2 [date] =&gt; 2007 ) [1] =&gt; Array ( [minus] =&gt; 1 [date] =&gt; 2008 ) [2] =&gt; Array ( [minus] =&gt; 1 [date] =&gt; ) [3] =&gt; Array ( [plus] =&gt; 1 [date] =&gt; 2010 [minus] =&gt; 1 ) ) </code></pre> <p>I have been trying to combine them into this:</p> <pre><code>Array ( [0] =&gt; Array ( [date] =&gt; 2007 [plus]=&gt; 2) [1] =&gt; Array ( [date] =&gt; 2008 [minus]=&gt; 1) [2] =&gt; Array ( [date] =&gt; 2009 [plusMinus]=&gt; 0) [3] =&gt; Array ( [date] =&gt; 2010 [plus] =&gt; 1 [minus]=&gt;1 ) ... ) </code></pre> <p>So basically I want to check if a value of the date array exists in the plusMinus array. If true the date and values from the plusMinus array shall replace the entry in the date array. If false, the original date array entry is complemented by a [plusMinus] => 0 key-value pair.</p> <p>The way I have tried to do it is this:</p> <pre><code>foreach ($filler as $key1 =&gt; $value1) { foreach ($plusMinus as $key2 =&gt; $value2) { if ($value1['0'] !== $value2['date']) { $value1['plusMinus'] = '0'; $result2[$key1][] = $value1; } elseif ($value1['0'] == $value2['date']) { if (array_key_exists('plus',$value2)) { $value1['plus'] = $value2['plus']; $result2[$key1][]=$value1; } elseif(array_key_exists('minus',$value2)) { $value1['minus'] = $value2['minus']; $result2[$key1][]=$value1; } elseif(array_key_exists('minus',$value2) &amp;&amp; array_key_exists('plus',$value2)) { } } } } $valuesComplete = array(); foreach ($result2 as $value) { $result2 = $value['0']; array_push($valuesIncomplete, $result2); } return $valuesComplete; </code></pre> <p>Instead of the desired outcome described above I get this:</p> <pre><code>Array ( [0] =&gt; Array ( [0] =&gt; 2007 [plus] =&gt; 2 ) [1] =&gt; Array ( [0] =&gt; 2008 [plusMinus =&gt; 0 ) [2] =&gt; Array ( [0] =&gt; 2009 [plusMinus] =&gt; 0 ) [3] =&gt; Array ( [0] =&gt; 2010 [plusMinus] =&gt; 0 ) [4] =&gt; Array ( [0] =&gt; 2011 [plusMinus] =&gt; 0 ) [5] =&gt; Array ( [0] =&gt; 2012 [plusMinus] =&gt; 0 ) [6] =&gt; Array ( [0] =&gt; 2013 [plusMinus] =&gt; 0 ) ) </code></pre> <p>What am I missing? Thanks for any help!</p>

    2. COFirst of all for brevity kick those elseifs and use continue(in the loop) to see what you are doing please... I do not understand why people complicate things to get in to trouble...:)

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.

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