title: writing a php function to verify data in an array
body: <p>How would i go about writing a function that would handle the data in an array?</p>
  
  <p>What i mean is, can i use</p>
  
  <pre><code>function CheckStuff($_POST){}
  </code></pre>
  
  <p>instead of</p>
  
  <pre><code>function CheckStuff($_POST['var1'], $_POST['var2']){}
  </code></pre>
  
  <p>Reason im asking is i need the function to work through all the values stored in the array and there are quite a few.</p>
