19、multi_close($mh); 这里要做的就是打开多个curl句柄并指派给一个批处理句柄。然后你就只需在一个while循环里等它执行完毕。这个示例中有两个主要循环。第一个 do-while 循环重复调用 curl_multi_exec() 。这个函数是无隔断（non-blocking）的，但会尽可能少地执行。它返回一个状态值，只要这个值等于常量 curlm_call_multi_perform ，就代表还有一些刻不容缓的工作要做（例如，把对应url的http头信息发送出去）。也就是说，我们需要不断调用该函数，直到返回值发生改变。而接下来的 while 循环，只在 $active 变量为 t

20、rue 时继续。这一变量之前作为第二个参数传给了 curl_multi_exec() ，代表只要批处理句柄中是否还有活动连接。接着，我们调用 curl_multi_select() ，在活动连接（例如接受服务器响应）出现之前，它都是被“屏蔽”的。这个函数成功执行后，我们又会进入另一个 do-while 循环，继续下一条url?php/*snoopy - the php net clientauthor: monte ohrt copyright (c): 1999-2000 ispi, all rights reservedversion: 1.01 * this library is fre
