    <p>I am trying to use array_combine to combine two multi-dimensional arrays, but somehow not doing it correctly. </p> <p>Here is array1:</p> <pre><code>Array( [Nov 18, 2011] =&gt; Array( [C] =&gt; 107705.5792 [I] =&gt; 44561.52 ) [Nov 22, 2011] =&gt; Array( [C] =&gt; -8992.8352 ) ) </code></pre> <p>and here is array2:</p> <pre><code>Array( [Nov 18, 2011] =&gt; Array( [C] =&gt; 3 [I] =&gt; 1 ) [Nov 22, 2011] =&gt; Array( [C] =&gt; 2 ) ) </code></pre> <p>Here is my attempt at array_combine, which is not working:</p> <pre><code>$array1 = ($arr1); $array2 = ($arr2); $result = array_combine($arr1, $arr2); echo '&lt;pre&gt;'; print_r($result); echo '&lt;/pre&gt;'; </code></pre> <p>What am I doing wrong? This is the result that I am looking for:</p> <pre><code>Array( [Nov 18, 2011] =&gt; Array( [3] =&gt; 107705.5792 [1] =&gt; 44561.52 ) [Nov 22, 2011] =&gt; Array( [2] =&gt; -8992.8352 ) ) </code></pre> <p>Thanks for your help.</p> <ul> <li>EDIT -</li> </ul> <p>I have found that if I instead use array_merge_recursive, this is my the result that I get. Not what I was looking for, but close:</p> <pre><code>Array( [Nov 18, 2011] =&gt; Array( [C] =&gt; Array( [0] =&gt; 3 [1] =&gt; 107705.5792 ) [I] =&gt; Array( [0] =&gt; 1 [1] =&gt; 44561.52 ) ) [Nov 22, 2011] =&gt; Array( [C] =&gt; Array( [0] =&gt; 2 [1] =&gt; -8992.8352 ) ) ) </code></pre> <ul> <li>FURTHER EDIT -</li> </ul> <p>Here is the way that I have tried to implement one of the suggestions below, however this is not working for me. What is wrong?:</p> <pre><code>function cust_array_merge(array &amp;$array1, array $array2){ // loop through main array foreach ($array1 as $key =&gt; $val) { // check if $array2 has the same index if (array_key_exists($key, $array2)) { // reset $array1's indexes to $array2's values foreach ($array2[$key] as $subKey =&gt; $subVal) { if (array_key_exists($subKey, $array1[$key])) { $tempVal = $array1[$key][$subKey]; unset($array1[$key][$subKey]); $array1[$key][$subVal] = $tempVal;}}}}} $merged = cust_array_merge($arr_cats_per_bill_date, $arr_cvat); echo '&lt;pre&gt;'; print_r($merged); echo '&lt;/pre&gt;'; </code></pre>

    1. COAre you wanting to keep key references or do you not care if it becomes 0 1 2? You can't have two keys of "C" or "I" or any other value in your array.

    2. COWhy do literally **ALL** of your questions have the exact same content and arrays? Are we doing your homework or something for school? This is literally the _third_ or _fourth_ question of yours that I've seen in the last week or two that is almost exactly the same as the previous one..

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.
