<p>What does the <em>=&amp;</em> assigment operator mean in PHP? I could not find any reference in PHP Manual in assignment section.</p>

<p>I saw it in a class instantiation, so I quite don't understand what's the difference between <em>=&amp;</em> and solely <em>=</em>.</p>

<p>Thanks in advance!  </p>
