mb_ereg_replace — Replace regular expression with multibyte support

### Descripción

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

Scans `string` for matches to `pattern` , then replaces the matched text with `replacement`

### Lista de parámetros

`pattern`

  The regular expression pattern.

  Multibyte characters may be used in `pattern` .

`replacement`

  The replacement text.

`string`

  The string being checked.

`option`
  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.

### Valores retornados

The resultant string on success, or `FALSE` on error.

### Notes

> Note: The internal encoding or the character encoding specified by mb_regex_encoding() will be used as the character encoding for this function.

Warning

Never use the e modifier when working on untrusted input. No automatic escaping will happen (as known from preg_replace()). Not taking care of this will most likely create remote code execution vulnerabilities in your application.
