php中fsockopen用法实例
这篇文章主要介绍了php中fsockopen用法,实例分析了fsockopen的创建、写入及关闭等具体流程,需要的朋友可以参考下
本文实例讲述了php中fsockopen用法。分享给大家供大家参考。
具体实现方法如下:
复制代码 代码如下:
$fp=fsockopen("127.0.0.1",80); //打开数据流
if(!$fp) //如果打开出错
{
echo "unable to openn"; //输出内容
}
else //如果成功打开
{
fwrite($fp,"get / http/1.0rnrn"); //向数据流写入内容
stream_set_timeout($fp,2); //进行超时设置
$res=fread($fp,2000); //读取内容
$info=stream_get_meta_data($fp); //获取数据流报头
fclose($fp); //关闭数据流
if($info['timed_out']) //如果超时
{
echo 'connection timed out!'; //输出内容
}
else
{
echo $res; //输出读取内容
}
}
//实例二
//创建服务端
$socket=stream_socket_server("tcp://0.0.0.0:8000",$errno,$errstr);
//如果创建失败
if(!$socket)
{
echo "$errstr ($errno)
n";
}
//如果创建成功
else
{
//接受连接
while($conn=stream_socket_accept($socket))
{
//写入数据
fwrite($conn,'the local time is '.date('n/j/y g:i a')."n");
//关闭连接
fclose($conn);
}
//关闭socket
fclose($socket);
}
//
$file="test.txt"; //定义文件
$fp=fopen($file,"w"); //打开数据流
if($fp) //如果成功打开
{
stream_set_write_buffer($fp,0); //设置缓冲区
fwrite($fp,$output); //写入内容
fclose($fp); //关闭数据流
}
希望本文所述对大家的php程序设计有所帮助。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
