what does "&" mean in front of classes in php?
<p>I've just inherited this code in PHP which seems to do some kind of web service call to googles api. I'm not quite an expert on PHP and there is a few syntax questions I have specifically relating to the following line
    $soapClients = &amp;APIlityClients::getClients();</p>

<p>I understand the double "::" as indicating that APIlityClients is a static class but I'm not sure what the "&amp;" in front of APIlityClients means.</p>
