    copied!<p>I have tried this now about 20 different ways, set it down and picked it back up several times and I am at a loss for what I am doing wrong. I am trying to create an array of arrays from three separate arrays. The first array I iterate through is a list of dates. Then I iterate through a list of cabins (this is a simple camp scheduling program), and then I randomly assign an activity to each of the cabins from a third array.</p> <p>The three arrays are <code>$cabins</code>, <code>$activities</code>, and <code>$checkeddates</code></p> <pre><code>//swaps key-value so cabin names are keys $cabins = array_flip( $cabins ); //sets each key value pair to be cabinname=&gt; null erase_val( $cabins ); foreach ( $checkeddates as $dates ) { $uberarray[] = $dates; } $uberarray = array_flip( $uberarray ); foreach ( $uberarray as $k =&gt; $v ) { $uberarray[$k] = $cabins; } </code></pre> <p>At this point, a var_dump shows that I have an array of dates each containing an array of cabins names with null values, from this point I have tried a dozen things and this is just where I left it, trying a process of elimination to figure out what it isn't.</p> <pre><code>foreach ( $uberarray as $k =&gt; $v ) { shuffle( $activities ); $s = $activities[0]; $uberarray[] = $s; } </code></pre> <p>In the end, I was thinking to build the large array (with some additional rules not yet written in to prevent multiple assignments of the same thing and such. And then as one function I would iterate through the established combinations in the array to write it to the database. </p> <p><strong>Edit</strong>: Request for how I want it to look in the end:</p> <pre><code>array 'ThuJan1st' =&gt; array 'cabin 1' =&gt; randomactivity1 'cabin 2' =&gt; randomactivity2 'cabin 3' =&gt; randomactivity3 </code></pre> <p>Currently I have 2 out of 3, but I can not seem to randomly add the activities as values.</p> <p><strong>Edit</strong>: This is what @kunal 's suggestion produced: </p> <pre><code>array 'ThuJan1st' =&gt; array 'cabin 1' =&gt; randomactivity1 'cabin 2' =&gt; randomactivity2 'cabin 3' =&gt; randomactivity3 array 'FriJan2nd' =&gt; array 'cabin 1' =&gt; randomactivity4 'cabin 2' =&gt; Null 'cabin 3' =&gt; Null </code></pre> <p>Once it iterated through activities a single time, nothing else was assigned a value.</p>
