PHP POST Request HTTP interface

Here is the curl way, so we must first ensure that the Curl function library open: In the php.ini file, extension=php_curl.dll before the semicolon removed

Code on:

/**
 * analog post for URL request
 * @param string $url
 * @param array $post _data
/function request_post ($url = ' ', $post _data = Array ()) {//url is required  if the address does not require an argument, the If
     (empty ($url)) {return
         false;
     }
     
    if (!empty ($post _data)) {
     $params = ';
      foreach ($post _data as $k => $v) 
      { 
          $params. = "$k =". UrlEncode ($v). "&";
         $params. = "$k =". $v. "&";
      }
      $params = substr ($params, 0,-1); 
     $ch = Curl_init ()///Initialize Curl
     curl_setopt ($ch, Curlopt_url, $url);//crawl The specified page
     curl_setopt ($ch, Curlopt_header, 0)//Set Header
     curl_setopt ($ch, Curlopt_returntransfer, 1),//request result string and output to screen
     curl_setopt ($ch, Curlopt_ POST, 1);//post Submission Mode
     if (!empty ($post _data)) curl_setopt ($ch, Curlopt_postfields, $params);
     $data = curl_exec ($ch);//Run Curl
     curl_close ($ch);
     return $data;
}

Test without parameters

Request_post (' http://www.baidu.com ');

With parameters

$post _data[' id ']= ' 1 ';

Request_post (' http://www.baidu.com ', $post _data);
