What does the $GLOBALS['s'] variable contain? It looks like an empty array, but what would it normally hold?
I've encountered it in a tutorial: The WordPress Theme: Single Post, Post Attachment, & 404 Templates, it mentions a long string that gets passed to a printf
function call.
The string looks something like this:
//START OF STRING
$entry_utility = <<<LONGSTR

LONGSTR;
//END OF STRING
NOTE: I've wrapped the long string from the tutorial inside a HEREDOC string instead, it was too hard to follow on the single line.
I've wrapped the $s variables in curly-brackets in case heredocs couldn't interpret them correctly.
