title: Code Igniter POST Variable
body: <p>I am brand new to Code Igniter but I can't seem to find a way to do this in the documentation,
  In normal PHP you can retrieve the contents of the entire POST variable like this</p>
  
  <p><code>$_POST = $postedVars</code></p>
  
  <p>But I can't seem to find something that does this in the same manner, I've tried</p>
  
  <p><code>$arr = $this-&gt;input-&gt;post;</code></p>
  
  <p>and</p>
  
  <p><code>$arr = $this-&gt;input-&gt;post();</code></p>
  
  <p>With no luck! Is this possible in CI? Thanks in advance!</p>
