CURL method is very popular so yes it is good to use it  You could also explain more those codes with some extra comments because starters could understand them

Assuming your php install has the CURL extension  it is probably the easiest way  and most complete  if you wish    Sample snippet     set POST variables  url    http   domain com get-post php    fields   array                         lname   gt urlencode  last name                          fname   gt urlencode  first name                          email   gt urlencode  email                       url-ify the data for the POST foreach  fields as  key  gt  value     fields string     key      value   amp      rtrim  fields string   amp        open connection  ch   curl init       set the url  number of POST vars  POST data curl setopt  ch CURLOPT URL   url   curl setopt  ch CURLOPT POST  count  fields    curl setopt  ch CURLOPT POSTFIELDS   fields string      execute post  result   curl exec  ch      close connection curl close  ch     Credits go to http   php dzone com  Also  don t forget to visit the appropriate page s  in the PHP Manual

For those using cURL  note that CURLOPT POST option is taken as a boolean value  so there s actually no need to set it to the number of fields you are POSTing  Setting CURLOPT POST to TRUE  i e  any integer except zero  will just tell cURL to encode the data as application x-www-form-urlencoded  although I bet this is not strictly necessary when you re passing a urlencoded string as CURLOPT POSTFIELDS  since cURL should already tell the encoding by the type of the value  string vs array  which this latter option is set to  Also note that  since PHP 5  you can use the http build query function to make PHP urlencode the fields array for you  like this   curl setopt  ch  CURLOPT POSTFIELDS  http build query  fields

Possibly the easiest way to make PHP perform a POST request is to use cURL  either as an extension or simply shelling out to another process  Here s a post sample      where are we posting to   url    http   foo com script php       what post fields   fields   array      field1    gt   field1      field2    gt   field2         build the urlencoded data  postvars   http build query  fields       open connection  ch   curl init        set the url  number of POST vars  POST data curl setopt  ch  CURLOPT URL   url   curl setopt  ch  CURLOPT POST  count  fields    curl setopt  ch  CURLOPT POSTFIELDS   postvars       execute post  result   curl exec  ch       close connection curl close  ch     Also check out Zend Http set of classes in the Zend framework  which provides a pretty capable HTTP client written directly in PHP  no extensions required    2014 EDIT - well  it s been a while since I wrote that  These days it s worth checking Guzzle which again can work with or without the curl extension

For PHP processing  look into cURL  It will allow you to call pages on your back end and retrieve data from it  Basically you would do something like this    ch   curl init    curl setopt  ch  CURLOPT RETURNTRANSFER  1   curl setopt   ch  CURLOPT URL  fetch url   curl setopt   ch  CURLOPT HTTPHEADER   headers   curl setopt   ch CURLOPT USERAGENT   user agent  curl setopt   ch CURLOPT CONNECTTIMEOUT 60    response   curl exec    ch    curl close  ch     You can also look into the PHP HTTP Extension

Like the rest of the users say it is easiest to do this with CURL  If curl isn t available for you then maybe http   netevil org blog 2006 nov http-post-from-php-without-curl If that isn t possible you could write sockets yourself http   petewarden typepad com searchbrowser 2008 06 how-to-post-an html

Although not ideal  if the cURL option doesn t do it for you  may be try using shell exec
