title: Display array values in PHP
body: <p>So, I'm working with PHP for the first time and I am trying to retrieve and display the values of an array. After a lot of googling, the only methods I can find for this are <code>print_r</code>, <code>var_dump</code> or <code>var_export</code>. However, all of these methods return something that looks like this:</p>
  
  <pre><code>[a] =&gt; apple
  [b] =&gt; banana
  [c] =&gt; orange
  </code></pre>
  
  <p>I can't figure out how to style this outout. I need to strip away the <code>[a] =&gt;</code> part and add commas. I know this must be a pretty straightforward process but I haven't been able to track down any documentation that demonstrates how to do it. </p>
