Evaluate a function, except the last word at the end

Evaluate a function. The last character except the tail is as follows;
$ Str = "Demi, an earthquake city. ";
$ Str = "winter! ";


Do not use the last punctuation mark. how can this problem be achieved? It is a Chinese character.

Iconv_set_encoding ("internal_encoding", "GBK"); // modify echo iconv_substr based on your character set ("Zhenming city, earthquake city. ", 0,-1), PHP_EOL; echo iconv_substr (" about winter! ", 0,-1), PHP_EOL;

Jinmi city of the epicenter
Appointment in winter

[Code = php] iconv_set_encoding ("internal_encoding", "GBK"); // modify according to your character set
Appointment in winter

Thank you, Big Brother.
