I am using Amazon API to display dvd and bluray product information on my website. I have the following PHP code that looks up product information based on its ItemID.
$movies = file_get_contents('movies.xml');
$xml = new SimpleXmlElement($movies);
$dvd = $xml->movie->amazon->dvd;
$bluray = $xml->movie->amazon->bluray;
$request = aws_signed_request('co.uk', array(
'Operation' => 'ItemLookup',
'ItemId' => '$dvd, $bluray',
'ResponseGroup' => 'Medium, Offers',
'MerchantId' => 'All'), $public_key, $private_key, $associate_tag);
I know the following line of code causes the problem:
'ItemId' => '$dvd, $bluray'
I'm not sure how I can assign two variables inside the array wrapped in single quotes.
If I assign direct values to ItemId, then everything works:
$request = aws_signed_request('co.uk', array(
'Operation' => 'ItemLookup',
'ItemId' => 'B004Q9SZGC, B004Q9T6CO',
'ResponseGroup' => 'Medium, Offers',
'MerchantId' => 'All'), $public_key, $private_key, $associate_tag);
However, I would like to use my $dvd
and $bluray
variables to look up ItemId stored in the local XML file (movies.xml) rather than hardcode the actual ItemId value inside the array.

In PHP you can concatenate expressions (e.g. variables and strings) with the .
sign.
For example:
'ItemId' => $dvd.', '.$bluray,
