Php:6 get and Post request sending method _php Tutorial

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:

 
 

  
  
 
   
  //get comment count, argument is article ID     
 
   
  function   getcommcount (  $postid  )   
 
   
  { 
 
   
   $jsondata  span> =  file_get_contents   (  ); Sets true to return an array, not set or false to return an object   $resjson   = Json_decode (  $jsondata  , True);  return     $resjson   [   [  $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:

 
  
  

  
   
   
 
  
   
   
$url = ' http://www.ido321.com/'
  
   
   
$htmlfile_get_contents($url
  
   
   
echo$html
  
   
   


 
  
  

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

 
  
  
 
   
   
   $fp   =  fopen   (  $url  ,   ' R '  );   
 
   
   
  stream_get_meta_data ( $fp  );   
 
   
   
  while   (!  feof   (  $fp  )) {  
 
   
   
   $result  . =  fgets   (  $fp  , 1024x768);   
 
   
   
 }  
 
   
   
  echo     " 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

 
 

  
  

  
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, 1024x768);
  
  

  
}
  
  

  
Fclose ($fp);
  
  

  
return   $result;
  
  

  
}
  
  

  
}
  
  

  
//Get 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;
  
  

  
}

 
 

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

 
 

  
  

  
function http_post ($URL,$data,$cookie,  $referrer ='') 
  
  

  
{
  
  

  
//parsing the given URL  
  
  

  
$URL _info = Parse_url ($URL);
  
  

  

  
  

  
//Building referrer  
  
  

  
if ($referrer= =") //If not given with this script as referrer  
  
  

  
$referrer = ' 111 ' ; 
  
  

  

  
  

  
//making string from $data  
  
  

  
foreach (    $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 post-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; 
  
  

  
}
 
 

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:  //www.ido321.com/');     
 
   
  curl_setopt ( $ch  , Curlopt_returntransfer, 1); /span>  
 
   
  curl_setopt ( $ch  , Curlopt_connecttimeout ,   $timeout  );   
 
   
   $file _contents   = curl_exec (  $ch  );   
 
   
  curl_close ( $ch  );   
 
   
  echo     $file _contents  ;
