title: Using braces with dynamic variable names in PHP
body: <p>I'm trying to use dynamic variable names (I'm not sure what they're actually called) But pretty much like this:</p>
  
  <pre><code>for($i=0; $i&lt;=2; $i++) {
      $("file" . $i) = file($filelist[$i]);
  }
  
  var_dump($file0);
  </code></pre>
  
  <p>The return is <code>null</code> which tells me it's not working. I have no idea what the syntax or the technique I'm looking for is here, which makes it hard to research. <code>$filelist</code> is defined earlier on.</p>
