I have some basic PHP code:
$raceramps56[\"short\"] = \"My Test Product\";
$leftMenu =
\'
I thought I'd provide some extra information just so you understand.
In your code:
$raceramps56["short"] = "My Test Product";
$leftMenu =
'';
You are including literally.
Take a read of this. http://php.net/manual/en/language.types.string.php
When I was first learning, I did not understand the different between literal ' and double quotes and it especially caused problems when I was trying to echo things.
Take a look at this:
If you were to use " " instead of ' you would not get the same output because " will interpret everything rather then take it literally.
I hope this has been of additional help, even though you have had your question answered already.
