I have a php script that returns just plain text without any html. Now I want to make a cURL request to that script and I get the following response:

HTTP/1.1 200 OK
Server: nginx/1.0.0
Date: Tue, 14 Feb 2012 14:38:46 GMT
Content-Type: text/html
Transfer-Encoding: chunked
Connection: keep-alive
X-Powered-By: PHP/5.3.8

The actuall response is just the XML.want to retrieve it from the response above by just removing the header information.



$url = $_GET['url'];

if ( !$url ) {

  // Passed url not specified.
  $contents = 'ERROR: url not specified';
  $status = array( 'http_code' => 'ERROR' );

} else if ( !preg_match( $valid_url_regex, $url ) ) {

  // Passed url doesn't match $valid_url_regex.
  $contents = 'ERROR: invalid url';
  $status = array( 'http_code' => 'ERROR' );

} else {
  $ch = curl_init( $url );

  if ( strtolower($_SERVER['REQUEST_METHOD']) == 'post' ) {
    curl_setopt( $ch, CURLOPT_POST, true );
    curl_setopt( $ch, CURLOPT_POSTFIELDS, $_POST );
  }

  curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );
  curl_setopt( $ch, CURLOPT_HEADER, true );
  curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );

  curl_setopt( $ch, CURLOPT_USERAGENT, $_GET['user_agent'] ? $_GET['user_agent'] : $_SERVER['HTTP_USER_AGENT'] );

  list( $header, $contents ) = preg_split( '/([\r\n][\r\n])\\1/', curl_exec( $ch ), 2 );

  $status = curl_getinfo( $ch );

  curl_close( $ch );
}

// Split header text into an array.
$header_text = preg_split( '/[\r\n]+/', $header );

if ( true ) {
  if ( !$enable_native ) {
    $contents = 'ERROR: invalid mode';
    $status = array( 'http_code' => 'ERROR' );
  }

  // Propagate headers to response.
  foreach ( $header_text as $header ) {
    if ( preg_match( '/^(?:Content-Type|Content-Language|Set-Cookie):/i', $header ) ) {
      header( $header );
    }
  }
  print $contents;
}
