best way to escape string for regex?

Some client content is starting to contain slashes and other oddities. Generally, preg_replace will give "unknown modifier" errors on the character directly following a slash in client content.

 

So, I've patched it using addcslashes, but I'm not sure I have the complete regex special character list. Is there a built-in php function that's eluding me, or is addcslashes the only way to go?

 

If the latter, I have "\/^$*+?.()|{}," -- am I missing any?
