Aaaaar matey. That's one dirty dawg of a problem, but I vanquished it 
last night convertin' my blog to pirate. Here's the trick, ya scurvy 
land lubber:

function myFunction($bits) {
     $text = $bits[1];
     // Now run the replacements on $text
     // ...
     return '>'.$text.'<';

$text = preg_replace_callback('/>(.*?)</s', 'myFunction', $text);

That thar snippet be just the trick. Now down yer grog, fire up yer 
hornpipe and find yerself a comely wench. Ye international talk like a 
pirate is almost at an end!
