During development, we often intercept strings as needed. If it is a string of English strings, it is fine, and there will be no garbled characters when we intercept it; but if it is a Chinese string, many times it will be intercepted based on the intercepted string. If the length is inappropriate, garbled characters will appear. Let’s implement a method to intercept Chinese strings without garbled characters:

'...'; } else { return $string; } } ?>
