title: In php, is 0 treated as empty?
body: <p>Code will explain more:</p>
  
  <pre><code>$var = 0;
  
  if (!empty($var)){
  echo "Its not empty";
  } else {
  echo "Its empty";
  }
  </code></pre>
  
  <p>The result returns "Its empty". I thought empty() will check if I already set the variable and have value inside. Why it returns "Its empty"??</p>
