That's the very problem. str_replace() works with no explicit LC_ALL setting, but str_ireplace() doesn't. That is rather misleading. I guess this should be mentioned in the docs. Previous Comments: ------------------------------------------------------------------------ [2017-09-18 14:33:21] cmb@php.net str_ireplace() regards the currently set locale, see <https://3v4l.org/AaXAm>, but apparently that is not mentioned in the documentation. ------------------------------------------------------------------------ [2017-09-18 14:29:03] requinix@php.net Virtually all of the regular string functions are not for multibyte encodings. ------------------------------------------------------------------------ [2017-09-18 14:28:23] spam2 at rhsoft dot net this is NOT a bug - most of the string funtion don't work for UTF8 at all and be warned about making decisions about strlen() on UTF8 strings http://php.net/manual/en/book.mbstring.php ------------------------------------------------------------------------ [2017-09-18 14:27:12] 1234ru at gmail dot com An actual example is this: echo str_ireplace("Б", "1", "БББббб"); // yelds 111ббб instead of 111111 (It doesn't allow me to edit the bug description so I post it as a comment.) ------------------------------------------------------------------------ [2017-09-18 14:20:25] 1234ru at gmail dot com Description: ------------ In other words, it simply ignores case-insensitive replacement when dealing with any letters except Latin. Not a single word in the documentation at http://php.net/str_ireplace covers the issue. And there is no corresponding mb* function. Test script: --------------- echo str_ireplace("б", "1", "111ббб"); // russian letters in UTF-8 encoding Expected result: ---------------- 111111 Actual result: -------------- 111ббб ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75225&edit=1
