This example describes how to implement httpRequest in php. Share it with you for your reference. The details are as follows:

I tried many methods to capture data from the website of the school library and then return it to the browser. First, I tried http_request (), but this school's pecl_http support, and later I tried the class HttpRequest, which is widely circulated on the Internet. It may be that I won't use it, but it also failed. Then we can see the function httpRequest ($ url, $ post = '', $ method = 'get', $ limit = 0, $ returnHeader = FALSE, $ cookie = '', $ bysocket = FALSE, $ ip = '', $ timeout = 15, $ block = TRUE). You can use it to share it. The function code is as follows:

The Code is as follows:

<? Php
/**
* Respose A Http Request
*
* @ Param string $ url
* @ Param array $ post
* @ Param string $ method
* @ Param bool $ returnHeader
* @ Param string $ cookie
* @ Param bool $ bysocket
* @ Param string $ ip
* @ Param integer $ timeout
* @ Param bool $ block
* @ Return string Response
*/
Function httpRequest ($ url, $ post = '', $ method = 'get', $ limit = 0, $ returnHeader = FALSE, $ cookie ='', $ bysocket = FALSE, $ ip = '', $ timeout = 15, $ block = TRUE ){
$ Return = '';
$ Matches = parse_url ($ url );
! Isset ($ matches ['host']) & $ matches ['host'] = '';
! Isset ($ matches ['path']) & $ matches ['path'] = '';
! Isset ($ matches ['query']) & $ matches ['query'] = '';
! Isset ($ matches ['Port']) & $ matches ['Port'] = '';
$ Host = $ matches ['host'];
$ Path = $ matches ['path']? $ Matches ['path']. ($ matches ['query']? '? '. $ Matches ['query']: ''): 'http: // www.jb51.net /';
$ Port =! Empty ($ matches ['Port'])? $ Matches ['Port']: 80;
If (strtolower ($ method) = 'post '){
$ Post = (is_array ($ post) and! Empty ($ post ))? Http_build_query ($ post): $ post;
$ Out = "POST $ path HTTP/1.0 \ r \ n ";
$ Out. = "Accept: */* \ r \ n ";
// $ Out. = "Referer: $ boardurl \ r \ n ";
$ Out. = "Accept-Language: zh-cn \ r \ n ";
$ Out. = "Content-Type: application/x-www-form-urlencoded \ r \ n ";
$ Out. = "User-Agent: $ _ SERVER [HTTP_USER_AGENT] \ r \ n ";
$ Out. = "Host: $ host \ r \ n ";
$ Out. = 'content-Length: '. strlen ($ post). "\ r \ n ";
$ Out. = "Connection: Close \ r \ n ";
$ Out. = "Cache-Control: no-cache \ r \ n ";
$ Out. = "Cookie: $ cookie \ r \ n ";
$ Out. = $ post;
} Else {
$ Out = "GET $ path HTTP/1.0 \ r \ n ";
$ Out. = "Accept: */* \ r \ n ";
// $ Out. = "Referer: $ boardurl \ r \ n ";
$ Out. = "Accept-Language: zh-cn \ r \ n ";
$ Out. = "User-Agent: $ _ SERVER [HTTP_USER_AGENT] \ r \ n ";
$ Out. = "Host: $ host \ r \ n ";
$ Out. = "Connection: Close \ r \ n ";
$ Out. = "Cookie: $ cookie \ r \ n ";
}
$ Fp = fsockopen ($ ip? $ Ip: $ host), $ port, $ errno, $ errstr, $ timeout );
If (! $ Fp) return ''; else {
$ Header = $ content = '';
Stream_set_blocking ($ fp, $ block );
Stream_set_timeout ($ fp, $ timeout );
Fwrite ($ fp, $ out );
$ Status = stream_get_meta_data ($ fp );
If (! $ Status ['timed _ out']) {// No timeout
While (! Feof ($ fp )){
$ Header. = $ h = fgets ($ fp );
If ($ h & ($ h = "\ r \ n" | $ h = "\ n") break;
}

$ Stop = false;
While (! Feof ($ fp )&&! $ Stop ){
$ Data = fread ($ fp, ($ limit = 0 ||$ limit> 8192? 8192: $ limit ));
$ Content. = $ data;
If ($ limit ){
$ Limit-= strlen ($ data );
$ Stop = $ limit <= 0;
}
}
}
Fclose ($ fp );
Return $ returnHeader? Array ($ header, $ content): $ content;
}
}
?>

The call is also very simple. Simple Example:

The Code is as follows:

Echo httpRequest ('HTTP: // www.baidu.com ');

I hope this article will help you with php programming.
