The substr () function is used to intercept strings, but there may be problems with Chinese characters. The two functions, mb_substr () and mb_strcut, can be used in a similar way to substr, you only need to add one more parameter at the end of the function to set the encoding of the string. in ini, open php_mbstring.dll.

<? Php header ("content-type: text/html; charset = UTF-8"); $ string = "hello, everyone"; echo strlen ($ string ).'
'; Echo mb_substr ($ string, 'utf-8 ').'...
'; Echo mb_strcut ($ string, 'utf-8').'... ';?>

Output result:

21
Hello, I am...
You...

From the above example, we can see that mb_substr separates characters by words, while mb_strcut separates characters by byte, but does not produce half a character.
