PHP removes the last character of the string with the use of substr and MB_SUBSTR

Normal string:

Original string: 1,2,3,4,5,6,

This string: 1,2,3,4,5,6, toward the last character of the Lost ","

Remove the last character "," and the end result is 1,2,3,4,5,6

$str = "1,2,3,4,5,6,"; $newstr = substr ($str, 0,strlen ($STR)-1); Echo $newstr;

Kanji string:

Original string: Wuzhou

Remove the last Chinese character "City", the end result for Wuzhou (Utf-8 code)

$get _city= ' Wuzhou '; $get _city=mb_substr ($get _city,0,strlen ($get _city)-3); echo $get _city;

The above describes the PHP removal of the last character of the string with substr and MB_SUBSTR usage, including the substr aspect of the content, I hope to be interested in PHP tutorial friends helpful.
