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
preg_replace() with the i modifier.
If search and replace are
arrays, then str_ireplace() takes a value from each
array and uses them to 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. The
converse would not make sense, though.
If search or replace
are arrays, their elements are processed first to last.
searchThe value being searched for, otherwise known as the needle. An array may be used to designate multiple needles.
replace
The replacement value that replaces found search
values. An array may be used to designate multiple replacements.
subjectThe string or array being searched and replaced on, otherwise known as the haystack.
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.
countIf passed, this will be set to the number of replacements performed.
Returns a string or an array of replacements.

Example #1 str_ireplace() example
<?php
$bodytag = str_ireplace("%body%", "black", "<body text=%BODY%>");
?>
Notă: Această funcție acceptă și date binare.
Because str_ireplace() replaces left to right, it might replace a previously inserted value when doing multiple replacements. Example #2 in the str_replace() documentation demonstrates how this may affect you in practice.
