str_ireplace

(PHP 5)

str_ireplace — Case-insensitive version of str_replace().

Description

mixed str_ireplace ( mixed $search , mixed $replace , mixed $subject [, int &$count ] )

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.

Parameters

search

Note: Every replacement with search array 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 .

Return Values

Returns a string or an array of replacements.

Changelog

Version Description
5.0.0 The count parameter was added.
