You don't need strtolower if you use the i modifier.

The content type should be safe (because set by some friendly code), but 
  your regexp matches ALL after the = (incl. any white space and further 
header content).

Maybe you can use this $GLOBALS['LANG']->csConvObj->parse_charset() if 
you expect variant spellings of the charsets. It will do the trimming 
and case lowering as well.
