title: Any equivalent to .= for adding to beginning of string in PHP?
body: <p>Just wondering if there is something like .= for adding text to the beginning of a string, e.g.:</p>
  
  <pre><code>$foo =. 'bar';
  </code></pre>
  
  <p>which doesn't work.</p>
  
  <p>Edit: example was originally <code>$foo =. $bar;</code> which can be achieved with <code>$bar .= $foo;</code></p>
