我通过一个连接发送和接收数据时检查了内存，而且我似乎正在清除变量，因为内存返回到之前的值。
但由于某些原因，如果我建立新连接，然后关闭连接，内存泄露。我相信当接受套接字时可能会出现问题。
我正在使用PHP 5.2.10
希望你们中的一个人能够找到时间与源头进行比赛，并找出出错的地方。提前致谢

编辑：抱歉，您可能需要将套接字接受更改回： if（$ newchannel = @socket_accept（$ socket ['socket']））

然后关闭连接，内存泄露
这是一个棘手的问题 - 即使是标准的引用计数垃圾收集器也只能以难以预测的间隔启动。调用gc_collect_cycles（）应该触发gc。每当你关闭一个连接时，请尝试调用它，看看它是否有所作为。
如果你仍然遇到问题 - 那么检查你是否已经编译了循环引用计数器 - 如果没有，那么就得到它。
答案 1 :(得分：-1)
关闭连接后，Channel数组从未删除过，令人惊讶的是没人接听。内存使用现在非常紧张。
未设置（这 - $＆GT;插座[$ socket_id] [ '通道'] [$ CHANNEL_ID]）;
但这确实意味着LOST_SOCKET_CHANNEL的任何事件暂时都没用。
当堆栈溢出允许时，将接受我自己的答案。谢谢你的帮助ppl ..我猜..
