title: What is this Colon inside foreach statement for php?
body: <p>Okay I am officially confused. 
  I'm reading up on this MVC intro in php and I see this code, and I added some items into array on top to see if it really works. </p>
  
  <pre><code>  &lt;?php 
   $members  = array('apple', 'oranges', 'banana');
    ?&gt;
  
  &lt;html&gt;
  &lt;h1&gt;Members of community.com:&lt;/h1&gt;
  &lt;ul&gt;
  &lt;?php foreach ($members as $i =&gt; $member) : ?&gt;
  &lt;li&gt;Member #&lt;?php echo $i + 1; ?&gt;: &lt;?php echo $member; ?&gt;&lt;/li&gt;
   &lt;?php endforeach; ?&gt;
   &lt;/ul&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>I notice there's a : in the line of the foreach statement. Where does this come from? More importantly, what is it?  Is this : symbol mean "okay we will continue this statement in the next line" ? </p>
  
  <p>But besides that, this is cool trick I learned. Less html tags inside my php echo's I guess.</p>
  
  <p>let me know what you think, thanks! </p>
