Example of collecting webpage content using fsockopen in php

Fsockopen is a practical function in php. Next I will introduce the program that uses the fsockopen function to collect web pages. If you need it, please refer to it.

Usage
Int fsockopen (string hostname, int port, int [errno], string [errstr], int [timeout]);

A collection page instance

The Code is as follows:

Copy code

<? Php Function get_url ($ url, $ cookie = false) { $ Url = parse_url ($ url ); $ Query = $ url [path]. "?". $ Url [query]; Echo "Query:". $ query; $ Fp = fsockopen ($ url [host], $ url [port]? $ Url [port]: 80, $ errno, $ errstr, 30 ); If (! $ Fp ){ Return false; } Else { $ Request = "GET $ query HTTP/1.1rn "; $ Request. = "Host: $ url [host] rn "; $ Request. = "Connection: Closern "; If ($ cookie) $ request. = "Cookie: $ cookien "; $ Request. = "rn "; Fwrite ($ fp, $ request ); While (! @ Feof ($ fp )){ $ Result. = @ fgets ($ fp, 1024 ); } Fclose ($ fp ); Return $ result; } } // Obtain the html part of the url and remove the header Function GetUrlHTML ($ url, $ cookie = false) { $ Rowdata = get_url ($ url, $ cookie ); If ($ rowdata) { $ Body = stristr ($ rowdata, "rnrn "); $ Body = substr ($ body, 4, strlen ($ body )); Return $ body; } Return false; } ?>

Solution after being disabled

If fsockopen pfsockopen is disabled on the server, use other functions, such as stream_socket_client (). Note: The parameters of stream_socket_client () and fsockopen () are different.

Replace fsockopen (with stream_socket_client (, and then delete the port parameter "80" in the original fsockopen function and add it to $ host.

Example

The Code is as follows:	Copy code
$ Fp = fsockopen ($ host, 80, $ errno, $ errstr, 30 ); Or $ Fp = fsockopen ($ host, $ port, $ errno, $ errstr, $ connection_timeout ); After modification: $ Fp = stream_socket_client ("tcp: //". $ host. "80", $ errno, $ errstr, 30 ); Or $ Fp = stream_socket_client ("tcp: //". $ host. ":". $ port, $ errno, $ errstr, $ connection_timeout );
