This function returns a string or an array with all occurrences of
search in subject
(ignoring case) replaced with the given replace
value. If you don't need fancy replacing rules, you should generally
use this function instead of eregi_replace() or
preg_replace() with the i modifier.
searchNote: Every replacement with
searcharray is performed on the result of previous replacement.
replace
subject
If subject is an array, then the search and
replace is performed with every entry of
subject, and the return value is an array as
well.
count
The number of matched and replaced needles will
be returned in count which is passed by
reference.
If search and replace are
arrays, then str_ireplace() takes a value from each
array and uses them to do search and replace on
subject. If replace has
fewer values than search, then an empty string is
used for the rest of replacement values. If search
is an array and replace is a string; then this
replacement string is used for every value of
search.
