mb_ereg_replace — Replace regular expression with multibyte support

### Description

string mb_ereg_replace ( string `$pattern` , string `$replacement` , string `$string` [, string `$option` ] )

mb_ereg_replace() scans `string` for matches to `pattern` , then replaces the matched text with `replacement` and returns the result string or `FALSE` on error. Multibyte character can be used in `pattern` .

Matching condition can be set by `option` parameter. If i is specified for this parameter, the case will be ignored. If x is specified, white space will be ignored. If m is specified, match will be executed in multiline mode and line break will be included in '.'. If p is specified, match will be executed in POSIX mode, line break will be considered as normal character. If e is specified, `replacement` string will be evaluated as PHP expression.

The internal encoding or the character encoding specified in mb_regex_encoding() will be used as character encoding.
