Printing out each array element
<p>I have an array and I use <code>print_r</code> and this what happen:</p>

<pre><code>Array
(
    [141] =&gt; 1
    [171] =&gt; 3
    [156] =&gt; 2
    [241] =&gt; 1
    [271] =&gt; 1
    [256] =&gt; 1
    [341] =&gt; 1
    [371] =&gt; 1
    [356] =&gt; 1
    [441] =&gt; 1
    [471] =&gt; 1
)
</code></pre>

<p>How can I print out the index [141] and so on?</p>
