title: Echo text if value of variable equals zero
body: <p>I have this code:</p>
  
  <pre><code>&lt;?php
  if ( $amount &lt; 5 ) {
    echo 'Credit Balance low! You have';
    echo $amount;
    echo ' remaining credits.';
  } else {
    echo 'No recent alerts...';
  }
  ?&gt;
  </code></pre>
  
  <p>Where it says <code>echo $amount;</code> I want to <code>echo $00.00</code> if the value of <code>$amount == 0</code>. How would I include this in my code?</p>
