Error when create array in php
<p>I have a sample code:</p>

<pre><code>$id = '1,2,3,4,5';
$name = 'Iphone 3,Iphone 3S,Iphone 4,Iphone 4S,Iphone 5';
$id_arr = array($id);
$name_arr = array($name);
$arr = array_combine($id_arr, $name_arr);
print_r($arr);
</code></pre>

<p>When I <code>print_r($arr)</code> is result is <code>([1,2,3,4,5] =&gt;'Iphone 3,Iphone 3S,Iphone 4,Iphone 4S,Iphone 5')</code></p>

<p>How to fix this is the result <code>([1]=&gt;'Iphone 3' [2] =&gt; 'Iphone 3S' ... [5]=&gt;'Iphone 5')</code></p>
