Echo foo based on if $bar is isset
<p>Normally when I retrieve an array from the database, I check to see if a certain element exists or is set to a certain value and echo text out accordingly:</p>

<pre><code>if (isset($bar)) // or is true 
{
  echo "something";
}
else  // elseif is set to false
{
  echo "not something";
}
</code></pre>

<p>But once you lots of variables, it can make your code quite an eyesore. I know you can easily create a function to do this, but does php provide an functionality built in to do this? What do fellow SOs do to get around this? </p>
