    mb_eregi_replace

    (PHP 4 >= 4.2.0, PHP 5)

    mb_eregi_replace — Replace regular expression with multibyte support ignoring case

    說明

    string mb_eregi_replace ( string $pattern , string $replace , string $string [, string $option = "msri" ] )

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

    參數

    pattern

    The regular expression pattern. Multibyte characters may be used. The case will be ignored.

    replace

    The replacement text.

    string

    The searched string.

    option
    option has the same meaning as in mb_ereg_replace().

    回傳值

    The resultant string or FALSE on error.

    註釋

    Note:

    mb_regex_encoding() 指定的內部編碼或字元編碼將會當做此函式用的字元編碼。

    Warning

    處理非信任的輸入時從不使用e 修飾字元，就不會轉法（即呼叫preg_replace()）。不注意這些很可能會導致應用程式引發遠端程式執行的漏洞。

    when trying to find a way to strip newline from a multibyte UTF-8 string i got to this function just to discover later that POSIX don't "do" newline so i can't strip them, examples of what i tried are : \r\n , \\r\\n , (\\r\\n) (\\r|\\n)

    and got no result
    so since i wanted something like mb_nl2br() that's simple i wrote this little recursive function for UTF-8:

    <?php
    function mb_str_replace($find,$replace,&$str)
    {
    $i = mb_strpos($str,$find, 0,"UTF-8");
    if (    $index===false) {return;}
    $str = mb_substr($str, 0,$i).$replace.mb_substr($str, $i+mb_strlen($find,"UTF-8"),mb_strlen($str,"UTF-8"));
    $this->mb_str_replace($find,$replace,$str);
    }
    ?>

    note: moderate unit tesing was done, changed to other encodings
