php中关于socket的系列函数总结,phpsocket系列函数

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):
复制代码 代码如下:
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:
复制代码 代码如下:
if(!extension_loaded('sockets')){
 if(strtoupper(substr(PHP_OS,3))=="WIN"){
  dl('php_sockets.dll');
 }else{
  dl('sockets.so');
 }
}

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。

socket_accept()    接受一个Socket连接
