PHP implementation method to imitate the socket request return page, phpsocket_php tutorial

PHP implements a method that mimics a socket request to return a page, Phpsocket

The example in this paper describes how the PHP implementation mimics the socket request return page. Share to everyone for your reference. The implementation method is as follows:

Copy CodeThe code is as follows: <?php
$url = "www.XXXX.com"; Do your own replacement
$parse = Parse_url ($url); Resolves the URL and returns the component.
$host = $parse [' Host '];
$path = $parse [' path '];
$port = 80;
$timeout = 80;
$fp = @fsockopen ($host, $port, $errno, $errstr, $timeout); Open the Socket link
if (! $fp) {
echo $errno. "　　--". $errstr; If error, return error code and error message
} else {
$out = "POST $path http/1.1\r\n"; The following is the HTTP request header information
$out. = "Host:". $host. " \ r \ n ";
$out. = "Accept: */*\r\n";
$out. = "connection:close\r\n";
$out. = "Cookie: $cookie \r\n\r\n";

@fwrite ($fp, $out); Write the request information to the link
$status = Stream_get_meta_data ($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 is the number of bytes that can be returned
$return. = $data;
}
}
Fclose ($FP);
Print_r ($return);
}

I hope this article is helpful to everyone's PHP programming.

PHP to a page 400 times the loop, each return time is variable, the result is often beyond the access time what should be done

1. Use JS Setinterval+ajax to request, PHP inside add conditions to determine whether the success;
2. Use the PHP recursive loop to do this, such as:


function test ($url)
{
echo $url. ' \t\n--------';
$r = @file_get_contents ($url);//I return the number of pages here, if there is no next page return 0, stop execution
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 uses sockets to get web content

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 ... the rest of the full text >>
