could someone help me with my ereg_replace converted to preg_replace

I just need a bit of help with my ereg_replace changed to preg_replace..

ereg_replace('<caption.*</caption>', '', $match);
 

and I've tried

preg_replace('/<caption.*</caption>/', '', $match);
 

but it doesn't work.. and it says "Warning: preg_replace(): Unknown modifier 'c'"

I'm new to this kinda thing.. so any help would be appreciated :)
