Php:6 kinds of Get and post request sending methods

In the I94web blog, I tried to Chang and say two social comment boxes, and later abandoned the smooth speech, unsafe.

I need to crawl the number of comments from the article remotely and then deposit it into the local database, whether it's a word or a lot. For more said, the requested format is as follows:

Gets the number of comments, the argument is the article IDfunction getcommcount ($postid) {    $jsondata = file_get_contents ("HTTP/ api.duoshuo.com/threads/counts.json?short_name=i94web&threads= $postid ");    //Set True to return an array, not set or false to return an object    $resjson = Json_decode ($jsondata,return $resjson [' response '][$ postid][' comments ');}     

There are a number of ways to do this for remote requests. Today, the LZ has collected six kinds, for everyone's reference.

1, use file_get_contents to get the content:

<?php$url=' http://www.ido321.com/'; $html = file_get_contents ($url);  Echo $html;? > 

2, open the URL with fopen, get the way to obtain

' R '); Stream_get_meta_data ($FP); while (!feof ($fp)) {$result. = fgets ($fp, 1024);} "URL body: $result"; fclose ($fp); 

3. Use file_get_contents to post to get content:

$data =Array (' foo ' = ' bar '), $data = Http_build_query ($data); $opts = Array (' http '  = = Array ( ' Method ' = ' POST ',' header ' = ' content-type:application/x-www-form-urlencodedrn '.' Content-length: '. Strlen ($data). ' rn ',' content ' = $data)); $context = Stream_context_create ($opts); $html = file_get_contents (' http://localhost/e/admin/test.html ',  False, $context); echo $html;               

4. Open the URL with the Fsockopen function, get the complete data in Get mode, including header and Body,fsockopen need php.ini allow_url_fopen option to open

functionGet_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 (! $fp) {Returnfalse;}else {$request =' GET $query http/1.1rn '; $request. = ' Connection:closern ' ; if ($cookie) $request. = ' Cookie: $cookien '; $request. =< Span style= "color: #006080;" > ' RN '; fwrite ($fp, $request); while ([email protected] ($fp)) {$result. = @fgets ($fp, 1024);} Fclose ($FP); return $result;}} //gets the HTML portion of the URL, removing headerfunction geturlhtml ($url, $ Cookie=false) {$rowdata = Get_url ($url, $cookie);  Rnrn '); $body =substr ($body, 4,strlen ($body)); return $body;} return false;}       

5. Open the URL with the Fsockopen function to get the complete data by post, including header and body

functionHttp_post ($URL, $data, $cookie, $referrer =‘‘){Parsing the given url$url_info=parse_url ($URL);Building referrerif ($referrer = =‘‘)If not given use this script as referrer$referrer=' 111 ';Making string from $dataforeach ($dataAs $key = $value) $values []=' $key = '. UrlEncode ($value); $data _string=implode (' & ', $values);Find out which port was needed–if not given use standard (=80)if (!Isset ($URL _info[' Port ']) $URL _info[' Port ']=80;Building post-request: $request. ="POST". $URL _info[' Path '."http/1.1n"; $request. =" Referer: $referern "; $request. =" Content-type:application/x-www-form-urlencodedn "; $request. = ' content-length: '. strlen ($data _string).  ' cookies: $cookien '; $request. = ' Port ']) ; Fputs ($fp, $request); while (!feof ($fp)) {$result. = fgets ($fp, 1024);} Fclose ($FP); return $result;}           

6. Using the Curl Library, before using the Curl Library, you may need to check to see if the php.ini has already turned on the Curl extension

$ch = Curl_init (); $timeout = 5;curl_setopt ($ch, Curlopt_url, ' http:echo $file _contents;
