syntax error with header

[cupboy]

I tried using this:
header(’Cache-Control: private, max-age=10800, pre-check=10800’);

results:
A PHP Error was encountered

Severity: Parsing Error

Message: syntax error, unexpected ':'

I don't see the problem.

PHP documentation: http://php.net/manual/en/function.header.php

Those quote characters you have there don't look right.

Well, that's what I get for copying and pasting something I saw on the web. Thanks!
