How I have to use

Answer 1

If using Curl in php...

function disguise_curl($url) 
{ 
  $curl = curl_init(); 

  // Setup headers - I used the same headers from Firefox version 2.0.0.6 
  // below was split up because php.net said the line was too long. :/ 
  $header[0] = "Accept: text/xml,application/xml,application/xhtml+xml,"; 
  $header[0] .= "text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"; 
  $header[] = "Cache-Control: max-age=0"; 
  $header[] = "Connection: keep-alive"; 
  $header[] = "Keep-Alive: 300"; 
  $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7"; 
  $header[] = "Accept-Language: en-us,en;q=0.5"; 
  $header[] = "Pragma: "; // browsers keep this blank. 

  curl_setopt($curl, CURLOPT_URL, $url); 
  curl_setopt($curl, CURLOPT_USERAGENT, 'Googlebot/2.1 (+http://www.google.com/bot.html)'); 
  curl_setopt($curl, CURLOPT_HTTPHEADER, $header); 
  curl_setopt($curl, CURLOPT_REFERER, 'http://www.google.com'); 
  curl_setopt($curl, CURLOPT_ENCODING, 'gzip,deflate'); 
  curl_setopt($curl, CURLOPT_AUTOREFERER, true); 
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); 
  curl_setopt($curl, CURLOPT_TIMEOUT, 10); 

  $html = curl_exec($curl); // execute the curl command 
  curl_close($curl); // close the connection 

  return $html; // and finally, return $html 
} 

// uses the function and displays the text off the website 
$text = disguise_curl($url); 
echo $text; 
?>

I understand you want to open a xml file using php. That's called to parse a xml file. The best reference is here.

http://php.net/manual/de/function.xml-parse.php

Answer 3

<?php
function wget($address,$filename)
{
  file_put_contents($filename,file_get_contents($address));
}
?>

use:

<?php
wget(URL, FileName);
?>

Answer 4

You can use curl in order to both fetch the data, and be identified (for both "basic" and "digest" auth), without requiring extended permissions (like exec or allow_url_fopen).

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/file.xml");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_USERPWD, "user:pass");
$result = curl_exec($ch);
curl_close($ch);

Your result will then be stored in the $result variable.

Answer 5

If the aim is to just load the contents inside your application, you don't even need to use wget:

$xmlData = file_get_contents('http://user:pass@example.com/file.xml');

Note that this function will not work if allow_url_fopen is disabled (it's enabled by default) inside either php.ini or the web server configuration (e.g. httpd.conf).

If your host explicitly disables it or if you're writing a library, it's advisable to either use cURL or a library that abstracts the functionality, such as Guzzle.

use GuzzleHttp\Client;

$client = new Client([
  'base_url' => 'http://example.com',
  'defaults' => [
    'auth'    => ['user', 'pass'],
]]);

$xmlData = $client->get('/file.xml');

This method is only one class and doesn't require importing other libraries or reusing code.

Personally I use this script that I made a while ago. Located here but for those who don't want to click on that link you can view it below. It lets the developer use the static method HTTP::GET($url, $options) to use the get method in curl while being able to pass through custom curl options. You can also use HTTP::POST($url, $options) but I hardly use that method.

/**
  *  echo HTTP::POST('http://accounts.kbcomp.co',
  *      array(
  *            'user_name'=>'demo@example.com',
  *            'user_password'=>'demo1234'
  *      )
  *  );
  *  OR
  *  echo HTTP::GET('http://api.austinkregel.com/colors/E64B3B/1');
  *                  
  */

class HTTP{
   public static function GET($url,Array $options=array()){
    $ch = curl_init();
    if(count($options>0)){
       curl_setopt_array($ch, $options);
       curl_setopt($ch, CURLOPT_URL, $url);
       $json = curl_exec($ch);
       curl_close($ch);
       return $json;
     }
   }
   public static function POST($url, $postfields, $options = null){
       $ch = curl_init();
       $options = array(
          CURLOPT_URL=>$url,
          CURLOPT_RETURNTRANSFER => TRUE,
          CURLOPT_POSTFIELDS => $postfields,
          CURLOPT_HEADER => true
          //CURLOPT_HTTPHEADER, array('Content-Type:application/json')
          ); 
       if(count($options>0)){
           curl_setopt_array($ch, $options);
       }
       $json = curl_exec($ch);
       curl_close($ch);
       return $json;
   }
}
