This example describes how php intercepts Chinese characters without garbled characters. Share it with you for your reference. The specific implementation method is as follows:

<? Php // $ str string to be intercepted // $ len number of characters to be intercepted // $ chars number of characters already intercepted // $ res saved string // $ chars saved already intercepted the number of strings // The offset intercepted by $ offset // The number of bytes of the $ length string // if the number of characters of $ len> $ str, result in unnecessary while LOOP, ($ offset <$ length limit) function utf8sub ($ str, $ len) {if ($ len <= 0) {return ;} $ res = ""; $ offset = 0; $ chars = 0; $ length = strlen ($ str); while ($ chars <$ len & $ offset <$ length) {$ hign = decbin (ord (substr ($ str, $ offset, 1); if (strlen ($ hign) <8) {$ count = 1 ;} elseif (substr ($ hign, 0, 3) = "110") {$ count = 2;} elseif (substr ($ hign, 1110) = "") {$ count = 3 ;} elseif (substr ($ hign, 11110) = "111110") {$ count = 4;} elseif (substr ($ hign,) = ") {$ count = 5;} elseif (substr ($ hign, 0,7) = "1111110") {$ count = 6;} $ res. = substr ($ str, $ offset, $ count); $ offset + = $ count; $ chars + = 1;} return $ res;} function utf8sub1 ($ str, $ len) {$ chars = 0; $ res = ""; $ offset = 0; $ length = strlen ($ str ); while ($ chars <$ len & $ offset <$ length) {$ Hign = decbin (ord (substr ($ str, $ offset, 1); if (strlen ($ hign) <8) {$ count = 1 ;} elseif ($ hign & "11100000" = "11000000") {$ count = 2;} elseif ($ hign & "11110000" = "11100000 ") {$ count = 3;} elseif ($ hign & "11111000" = "11110000") {$ count = 4 ;} elseif ($ hign & "11111100" = "11111000") {$ count = 5;} elseif ($ hign & "11111110" = "11111100 ") {$ count = 6;} $ res. = substr ($ str, $ offset, $ count); $ chars ++; $ offset + = $ count;} return $ res ;}$ a = "Chinese ah people Min hdj "; echo utf8sub ($ a, 5);?>
