file get contents behind a proxy

Question

At work we have to use a proxy to basically access port 80 for example  we have our own custom logins for each user   My temporary workaround is using curl to basically login as myself through a proxy and access the external data I need   Is there some sort of advanced php setting I can set so that internally whenever it tries to invoke something like file get contents   it always goes through a proxy  I m on Windows ATM so it d be a pain to recompile if that s the only way   The reason my workaround is temporary is because I need a solution that s generic and works for multiple users instead of using one user s credentials   Ive considered requesting a separate user account solely to do this but passwords change often and this technique needs to be deployed throughout a dozen or more sites    I don t want to hard-code credentials basically to use the curl workaround

Use stream context set default function  It is much easier to use as you can directly use file get contents or similar functions without passing any additional parameters  This blog post explains how to use it  Here is the code from that page    lt  php    Edit the four values below  PROXY HOST    proxy example com      Proxy server address  PROXY PORT    1234         Proxy server port  PROXY USER    LOGIN         Username  PROXY PASS    PASSWORD        Password    Username and Password are required only if your proxy server needs basic authentication   auth   base64 encode   PROXY USER  PROXY PASS    stream context set default   array     http    gt  array      proxy    gt   tcp    PROXY HOST  PROXY PORT       request fulluri    gt  true      header    gt   Proxy-Authorization  Basic  auth        Remove the  header  option if proxy authentication is not required             url    http   www pirob com     print r  get headers  url      echo file get contents  url     gt

To use file get contents   over through a proxy that doesn t require authentication  something like this should do     I m not able to test this one   my proxy requires an authentication    aContext   array       http    gt  array           proxy              gt   tcp   192 168 0 2 3128            request fulluri    gt  true             cxContext   stream context create  aContext     sFile   file get contents  http   www google com   False   cxContext    echo  sFile    Of course  replacing the IP and port of my proxy by those which are OK for yours  -   If you re getting that kind of error    Warning  file get contents http   www google com   function file-get-contents   failed to open stream  HTTP request failed  HTTP 1 0 407 Proxy Authentication Required   It means your proxy requires an authentication   If the proxy requires an authentication  you ll have to add a couple of lines  like this     auth   base64 encode  LOGIN PASSWORD      aContext   array       http    gt  array           proxy              gt   tcp   192 168 0 2 3128            request fulluri    gt  true           header             gt   Proxy-Authorization  Basic  auth              cxContext   stream context create  aContext     sFile   file get contents  http   www google com   False   cxContext    echo  sFile    Same thing about IP and port  and  this time  also LOGIN and PASSWORD  -  Check out all valid http options   Now  you are passing an Proxy-Authorization header to the proxy  containing your login and password   And    The page should be displayed  -
