title: Function verbosity when returning boolean value?
body: <p>Consider:</p>
  
  <pre><code>function something($x, $y)
  {
     if($x == $y){
        return True; 
     }
  }
  </code></pre>
  
  <p>If the the condition in the segment does not evaluate to true, does php require me to 
  explicitly return false?</p>
  
  <p>Example: </p>
  
  <pre><code>$condition = something(1,3);
  if(!$something){///}
  </code></pre>
  
  <p>Will <code>$condition</code> evaluate to false if declared like above?</p>
