    mb_eregi_replace

    (PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)

    mb_eregi_replace — Replace regular expression with multibyte support ignoring case

    说明

    mb_eregi_replace(
        string $pattern,
        string $replacement,
        string $string,
        ?string $options = null
    ): string|false|null

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

    参数

    pattern

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

    replacement

    The replacement text.

    string

    The searched string.

    options
    The search option. See mb_regex_set_options() for explanation.

    返回值

    The resultant string or false on error. If string is not valid for the current encoding, null is returned.

    更新日志

    版本 说明
    8.0.0 options is nullable now.
    7.1.0 The function checks whether string is valid for the current encoding.
    7.1.0 The e modifier has been deprecated.

    注释

    注意:

    mb_regex_encoding() 指定的内部编码或字符编码将会当作此函数用的字符编码。

    警告

    处理非信任的输入时从不使用 e 修饰符，就不会转码（即调用 preg_replace()）。不注意这些会很可能会导致应用程序引发远程代码执行的漏洞。

    $f = 'а';
    echo     preg_replace('/('.$f.')/iu', '<b>$1</b>', $s);

    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
