PHP implements HTTP request class _php techniques that support get,post,multipart/form-data

This article describes the PHP implementation of Get,post,multipart/form-data HTTP request class and its application, share for everyone to reference. Specifically as follows:

The HttpRequest.class.php class files are as follows:

<?php/** HttpRequest class, HTTP request class, support Get,post,multipart/form-data * date:2013-09-25 * author:fdipzone * Ve r:1.0 * * Func: * Public setconfig Setting Connection parameters * Public setformdata setting form data * Public setfiledata setting file data * Publi   C Send data * Private Connect Create connection * Private Disconnect disconnect * Private sendget get way, processing sent data, not processing file data * Private Sendpost post mode, processing the sent data * Private Sendmultipart multipart way, processing the sent data, send the file recommended Use this method * * Class httprequest{

The Demo sample program is as follows:

<?php 
require (' HttpRequest.class.php '); 
 
$config = Array ( 
      ' IP ' => ' demo.fdipzone.com ',//null) instead 
      of ' host ' => ' demo.fdipzone.com ', ' 
      port ' = >, 
      ' errno ' => ', ' 
      errstr ' => ', ' timeout ' => ', ' 
      url ' => '/getapi.php ', 
      //' URL ' => '/postapi.php ', 
      //' URL ' => '/multipart.php ' 
); 
 
$formdata = Array ( 
  ' name ' => ' Fdipzone ', ' 
  gender ' => ' man ' 
); 
 
$filedata = Array ( 
    ' name ' => ' photo ', ' 
    filename ' => ' photo.jpg ', 
    ' path ' => ') Photo.jpg ' 
  ) 
); 
 
$obj = new HttpRequest (); 
$obj->setconfig ($config); 
$obj->setformdata ($formdata); 
$obj->setfiledata ($filedata); 
$result = $obj->send (' get '); 
$result = $obj->send (' post '); 
$result = $obj->send (' multipart '); 
 
Echo ' <pre> '; 
Print_r ($result); 
Echo ' </pre> ';
