PHP实现模仿socket请求返回页面的方法,phpsocket

本文实例讲述了PHP实现模仿socket请求返回页面的方法。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:

 $url = "www.XXXX.com";  //自己做替换
 $parse = parse_url($url);  //对URL进行解析,返回起组成部分。
 $host = $parse['host'];
 $path = $parse['path'];
 $port = 80;
 $timeout = 80;
 $fp = @fsockopen($host, $port, $errno, $errstr, $timeout);  //打开socket链接
 if (!$fp){
     echo $errno."--".$errstr;  //如果错误,则返回错误代码和错误信息
 } else {
     $out = "POST $path HTTP/1.1\r\n";  //以下是HTTP请求头信息
     $out .= "Host: ".$host."\r\n";
     $out .= "Accept: */*\r\n";
     $out .= "Connection: Close\r\n";
     $out .= "Cookie: $cookie\r\n\r\n";
   
     @fwrite($fp, $out);  //把请求信息写到链接中
     $status = stream_get_meta_data($fp);
     if(!$status['timed_out']) {    
                 while (!feof($fp)) { 
                     if(($header = @fgets($fp)) && ($header == "\r\n" ||  $header == "\n")) {    
                         break;    
                     }    
                 }    
        
                 $stop = false;    
                 while(!feof($fp) && !$stop) {    
                     $data = fread($fp,8192);      //8192为可返回字节数
                     $return .= $data;        
                 }    
             }    
     fclose($fp);
     print_r($return);
 }

希望本文所述对大家的PHP程序设计有所帮助。

php 要对一个页面进行400多次的循环,每次返回时间不定,结果往往是超出访问时间这应该怎办

1.用js的setInterval+ajax来请求,PHP里面加条件判断是否成功;
2.用PHP递归循环来做,如:


function test($url)
{
echo $url.'\t\n--------';
$r = @file_get_contents($url);//我这里返回的是页数,如果没有下一页的时候返回0,停止执行
echo $r;
if($r > 0)
{
$url = 'test.com/1.php?p='.$r;
test($url);
}
else
{
echo 'fail';
}
}

$url = 'test.com/1.php?p=1';
$res = test($url);
?>
 

php使用socket获取网页内容

function GETBySocket($URL, $port=80) {
//get host from url
preg_match('/\/\/.*\//sU',$URL,$host_array);
if(!$host_array[0]) {
$URL.='/';
preg_match('/\/\/.*\//sU',$URL,$host_array);
}
$host=substr($host_array[0],2,-1);
//connect
$fp = stream_socket_client("$host:$port", $errcode, $errstr, 1);// or die("get ". $host ." failed");
//
$header = "GET ". $URL. " HTTP/1.1\r\n";
$header .= "Accept: */*\r\n";
$header .= "Accept-Language: zh-cn\r\n";
//$header .= "HTTP_CONNECTION: Keep-Alive\r\n";
$header .= "HTTP_ACCEPT: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5\r\n";
$header .= "HTTP_ACCEPT_CHARSET: gbk,*,utf-8\r\n";
//$header .= "Accept-Encoding: gzip, deflate\r\n";
$header .= "User-Agent: Mozilla/4.0(compatible; MSIE 6.0; Windows NT 5.1;)\r\n";
$header .= "Host: ". $host ."\r\n";
//$header .= "Connection: Keep-Alive\r\n";
//$header .= "Cookie: cnzz02=2; rtime=1; ltime=1148456424859; cnzz_eid=566......余下全文>>

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,
