PHP substr打破表情符号

I need to get only 30 characters from the paragraph submitted by user. In case the 30th character is an emoji, the output shows question marks. How can I avoid breaking the emojis?

echo substr("Hello world Hello world Hell

    I think the simplest solution would be to use mb_substr

    Performs a multi-byte safe substr() operation based on number of characters.

    php > $myvariable = array();
    php > $myvariable['hello'] = mb_substr("Hello world Hello world Hell
