(no version information, might be only in CVS)
This function returns a string or an array with all
occurences 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.
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.
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.
This function is binary safe.
