What is =& in PHP?

Question

Look at this example. There is a line:

  $client =& new xmlrpc_client(\'/xml-rpc\', \'api.quicktate.com\', 80);
  $client->return_type = \'xmlrpcvals         


        

Answer 1

The = and the & should* have a space between them - they're two different operators. The & means get a reference to this.

The -> is for object member access - this means assign 'xmlrpcvals' to the return_type member of $client.
