PHP 6 ways to send get, POST requests concise summary _php instances

This article mainly introduces the PHP send get, POST request 6 ways concise summary, respectively, use file_get_contents, fopen, Fsockopen, curl to send get and post requests, the need for friends can refer to

Method 1: Use file_get_contents to get the content in the Get mode:

<?php$url= ' http://www.jb51.net/'; $html = file_get_contents ($url); Echo $html; >

Method 2: Open the URL with fopen and get the content in get:

<?PHP$FP = fopen ($url, ' R '); Stream_get_meta_data ($FP); while (!feof ($fp)) {$result. = fgets ($fp, 1024);} echo "URL body: $result"; fclose ($FP);? >

Method 3: Use the file_get_contents function to get the URL by post

<?php$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://www.php.cn/', False, $context); Echo $html;? >

Method 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

<?phpfunction 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,); if (! $fp) { return false;} else {$request = "GET $query http/1.1rn"; $request. = "Host: $url [Host]rn"; $request. = "Connection:closern"; if ($cookie) $r Equest.= "Cookie:  $cookien"; $request. = "RN"; fwrite ($fp, $request); while (! @feof ($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, $cookie), or if ($rowdata) {$ Body= stristr ($rowdata, "rnrn"), $body =substr ($body, 4,strlen ($body)); return $body;} return false;}? >

Method 5: Use the Fsockopen function to open the URL, post to get the full data, including header and body

<?phpfunction http_post ($URL, $data, $cookie, $referrer = "") {//parsing the given url$url_info=parse_url ($URL);// Building Referrerif ($referrer = = "")//if not given with this script as referrer$referrer= "111″;//making string from $dataf Oreach ($data as $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 PO St-request: $request. = "POST". $URL _info["path"]. " http/1.1n "; $request. =" Host: ". $URL _info[" host "]." n "; $request. =" Referer: $referern "; $request. =" Content-type:application/x-www-form-urlencodedn "; $request. =" Content-length: ". strlen ($data _string)." n "; $request. =" Connection:closen "; $request. =" Cookie: $cookien "; $request. =" n "; $request. = $data _string." n "; $fp = Fsockopen ($URL _info[" host "], $URL _info[" Port "]), fputs ($fp, $request), while (!feof ($fp)) {$result. = fgets ($fp , 1024);} Fclose ($FP); return $result;}? >

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

<?php$ch = Curl_init (); $timeout = 5;curl_setopt ($ch, Curlopt_url, ' http://www.php.cn/'); curl_setopt ($ch, Curlopt_ Returntransfer, 1); curl_setopt ($ch, Curlopt_connecttimeout, $timeout); $file _contents = curl_exec ($ch); Curl_close ($ CH); echo $file _contents;? >
