In these cases, the result is NULL. It works well with PHP versions < 7.1 but fails with PHP 7.1 and above. Test script: --------------- mb_regex_encoding('SJIS'); $string = "hello ここに文を入れる。"; $pattern = "hello"; $replacement = 'hi'; //expected result: hi ここに文を入れる。 //but it returns NULL var_dump(mb_ereg_replace($pattern, $replacement, $string)); //Similar error for binary strings, you can test more here. //http://sandbox.onlinephpfunctions.com/code/1a741afb48b299c6f335d9175be730a5ec3854d5 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79118&edit=1
