  Instead of concatenating strings, I suggest to use the http_build_query()
function:

<?php
$data = array('param1' => 'val1',
              'param2' => 'val2',
              'param3' => 'val3');
$query = http_build_query($data);
echo "Query: {$query}\n";
 ?>

  So, to create a query string based on your $_POST request parameters,
you just need to use the function as follows:

<?php
$query = http_build_query($_POST);
echo "Query: {$query}\n";
 ?>

  This will create the proper query string to be used on your URL.
