php socket相关函数

本文列举了所有关于PHP语言中使用socket相关服务的一些函数。注意使用如下函数之前,你需要确保你的socket已打开,如果你没有打开,请编辑你的php.ini文件,去掉下面这行前面的注释(分号):

extension=php_sockets.dll

如果你无法去掉注释,那么请使用下面的代码来加载扩展库:

<?php
if(!extension_loaded('sockets')){
	if(strtoupper(substr(PHP_OS,3))=="WIN"){
		dl('php_sockets.dll');
	}else{
		dl('sockets.so');
	}
}
Copy after login

如果你不知道你的socket是否打开,那么你可以使用phpinfo()函数来确定socket是否打开。你通过查看phpinfo信息了解socket是否打开。
