title: returning variable from function
body: <p>This is probably not the wisest question, but is it possible to return a variable from a function without redeclaring it?</p>
  
  <pre><code>function test(){
  $a = 1;
  return $a;
  }
  </code></pre>
  
  <p>Would it somehow be possible to access $a with just calling the function? test();</p>
  
  <p>not $a = test();</p>
  
  <p>Is that the only way? I want to make $a available after calling the function.</p>
