does array_merge works on array of integers?
<p>Does array_merge works on array of integers.  </p>

<pre><code>$range = array_merge(range(1, 1)
                    , range(1,10));
</code></pre>

<p>and output is </p>

<pre><code>array(11) { [0]=&gt; int(1) [1]=&gt; int(1) [2]=&gt; int(2) [3]=&gt; int(3) [4]=&gt; int(4) [5]=&gt; int(5) [6]=&gt; int(6) [7]=&gt; int(7) [8]=&gt; int(8) [9]=&gt; int(9) [10]=&gt; int(10) } 
</code></pre>

<p>Edit:</p>

<p>To clarify, I was expecting that the second array would override the first, leaving only 1 element with <code>1</code> as a value. The result should have been</p>

<pre><code>    array(10) { [0]=&gt; int(1) [1]=&gt; int(2) [2]=&gt; int(3) [3]=&gt; int(4) [4]=&gt; int(5) [5]=&gt; int(6) [6]=&gt; int(7) [7]=&gt; int(8) [8]=&gt; int(9) [9]=&gt; int(10) } 
</code></pre>

<p>Why isn't it so?</p>
