The encoding of the php file itself should match the encoding of the web page.

A. if you want to use gb23 12 encoding, then php should output header ("content-type: text/html; Charset=gb23 12 "), adding static pages.

B. If utf-8 encoding is to be used, php should output header ("content-type: text/html; Charset=utf-8 "), static page addition; Parameter selection->; File-> UTF-8 signature, select Always Delete, and then save to delete BOM information.

Php itself is not Unicode, so functions such as substr should be changed to mb_substr (mbstring extension is required); Or transcode with iconv. ?

If your HTML file is garbled, you can add UTF8 coding (internationalization coding) to the head tag: UTF-8 has no national coding, so it can be used independently of any language.

Extended data:
