lots of methods available in php to read a file like exec, file_get_contents, curl and fopen but it depend on your requirement and file permission

Visit this file_get_contents vs cUrl

Basically file_get_contents for for you

$data = file_get_contents($file_url);

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    gt   http   example com      defaults    gt         auth       gt    user    pass           xmlData    client- gt get   file xml

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

wget  wget is a linux command  not a PHP command  so to run this you woud need to use exec  which is a PHP command for executing shell commands   exec  wget --http-user  user  --http-password  pass  http   www example com file xml      This can be useful if you are downloading a large file - and would like to monitor the progress  however when working with pages in which you are just interested in the content  there are simple functions for doing just that   The exec function is enabled by default  but may be disabled in some situations  The configuration options for this reside in your php ini  to enable  remove exec from the disabled functions config string   alternative  Using file get contents we can retrieve the contents of the specified URL URI  When you just need to read the file into a variable  this would be the perfect function to use as a replacement for curl - follow the URI syntax when building your URL      standard url  content   file get contents  http   www example com file xml        or with basic auth  content   file get contents  http   user pass www example com file xml      As noted by Sean the Bean - you may also need to change allow url fopen to true in your php ini to allow the use of a URL in this method  however  this should be true by default   If you want to then store that file locally  there is a function file put contents to write that into a file  combined with the previous  this could emulate a file download   file put contents  local file xml    content

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   gt  demo example com                   user password   gt  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 gt 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  gt  url            CURLOPT RETURNTRANSFER   gt  TRUE            CURLOPT POSTFIELDS   gt   postfields            CURLOPT HEADER   gt  true             CURLOPT HTTPHEADER  array  Content-Type application json                        if count  options gt 0               curl setopt array  ch   options                    json   curl exec  ch          curl close  ch          return  json
