什么是=&在PHP中? [英] What is =& in PHP?

问题描述

看这个例子.有一行:

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

=&是什么?$client->return_type中的->是什么意思?

What is the =& and what does the -> in $client->return_type mean?

推荐答案

=和&应该*之间有一个空格-它们是两个不同的运算符. &表示获取对此的引用.

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

->用于对象成员访问-这意味着将'xmlrpcvals'分配给$client的return_type成员.

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