Hello,

the proto for str_replace shows this:

/* {{{ proto mixed str_replace(mixed search, mixed replace, mixed subject [, bool boyer])
   Replaces all occurrences of search in haystack with replace */

What is that "boyer" parameter doing there? It seems that it selects a
different algorithm for str_replace, but what is the difference?
