str_ireplace — Case-insensitive version of str_replace().
This function returns a string or an array with all occurrences of
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.
replace are arrays, then str_ireplace() takes a value from each array and uses them to search and replace on
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.
replace are arrays, their elements are processed first to last.
The value being searched for, otherwise known as the needle. An array may be used to designate multiple needles.
The replacement value that replaces found
search values. An array may be used to designate multiple replacements.
The string or array being searched and replaced on, otherwise known as the haystack.
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 passed, this will be set to the number of replacements performed.

Example #1 str_ireplace() example
$bodytag = str_ireplace("%body%", "black", "<body text=%BODY%>");
Note: This function is binary-safe.
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.
