PHP 套接字链接,能否设置时间?该如何解决
PHP 套接字链接,能否设置时间?
- PHP code
<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); $IP=$row['IP']; $connection = socket_connect($socket, $IP, 2012);
貌似默认是30秒,要是连不上的话等的时间太长了,能否设置其只有10秒?
------解决方案--------------------
在线手册的用户注释区其实有很多有用的参考,你可以在 http://php.net/manual/en/function.socket-get-option.php 里搜索 timeout,因为这个问题很普遍,所以肯定会有。
如果你懒的动手,摘录一段代码给你
SO_SNDTIMEO Reports the timeout value specifying the amount of time that an output function blocks because flow control prevents data from being sent. array. The array will contain two keys: sec which is the seconds part on the timeout value and usec which is the microsecond part of the timeout value.
To set a socket timeout value (assuming you've set it blocking) use:
- PHP code
socket_set_option( $socket, SOL_SOCKET, // socket level SO_SNDTIMEO, // timeout option array( "sec"=>10, // Timeout in seconds "usec"=>0 // I assume timeout in microseconds ) );<br><font color="#e78608">------解决方案--------------------</font><br>

可以这样,把连接的php代码放到单独的一个文件中,用AJAX访问,结果放到一个div中
