* Note: Try to avoid using this function. Use api_preg_replace() with Perl-compatible regular expression syntax.
*
* Scans string for matches to pattern, then replaces the matched text with replacement, ignoring case, with extended multibyte support.
* By default this function uses the platform character set.
* @param string $pattern The regular expression pattern.
* @param string $replacement The replacement text.
* @param string $string The searched string.
* @param string $option (optional) Matching condition.
* If i is specified for the matching condition 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.
* @return mixed The modified string is returned. If no matches are found within the string, then it will be returned unchanged. FALSE will be returned on error.
* This function is aimed at replacing the functions eregi_replace() and mb_eregi_replace() for human-language strings.
