Location’s an illustration fixed successful the PHP guide, astatine this leaf : [HTTP discourse choices][2] *(quoting)* : ``` $postdata = http_build_query( array( ‘var1’ => ‘any contented’, ‘var2’ => ‘doh’ ) ); $opts = array(‘http’ => array( ’technique’ => ‘Station’, ‘header’ => ‘Contented-Kind: exertion/x-www-signifier-urlencoded’, ‘contented’ => $postdata ) ); $discourse = stream_context_create($opts); $consequence = file_get_contents(‘http://illustration.com/subject.php', mendacious, $discourse);
Fundamentally, you person to make a watercourse, with the correct choices *(location is a afloat database connected that leaf)*, and usage it arsenic the 3rd parameter to `file_get_contents` -- thing much ;-)
Arsenic a sidenote : mostly talking, to direct HTTP Station requests, we lean to usage curl, which offers a batch of choices an each -- however streams are 1 of the good issues of PHP that cipher is aware of astir... excessively atrocious...
