PHP that supports Chinese characters is split into array code by string length,

The following code is used to separate Chinese and English characters:

<? Phpfunction mbStrSplit ($ string, $ len = 1) {$ start = 0; $ strlen = mb_strlen ($ string); while ($ strlen) {$ array [] = mb_substr ($ string, $ start, $ len, "utf8"); $ string = mb_substr ($ string, $ len, $ strlen, "utf8"); $ strlen = mb_strlen ($ string);} return $ array;} header ('content-type: text/html; charset = UTF-8 '); $ str = 'I love Beijing 3 I love Shanghai-I love xianggang'; $ r = mbStrSplit ($ str, 4); echo '<pre>'; print_r ($ r ); echo '</pre>';?>

Running result:

Array ([0] => I love Beijing [1] => 3 I love [2] => sea-I love [3] => xian [4] => ggan [5] => g)

<? Php function str_split_unicode ($ str, $ l = 0) {if ($ l> 0) {$ ret = array (); $ len = mb_strlen ($ str, "UTF-8"); for ($ I = 0; $ I <$ len; $ I + = $ l) {$ ret [] = mb_substr ($ str, $ I, $ l, "UTF-8");} return $ ret;} return preg_split ("// u", $ str,-1, PREG_SPLIT_NO_EMPTY);}?> $ S = "if you do not want sss to see gfg do not rtret immortal"; // Mild milk print_r (str_split ($ s, 5); print_r (str_split_unicode ($ s, 5 )); // output // Array ([0] => [1] => �� for example, [2] => �� sss [3] => see gf [4] => g users [5] => �� rtr [6] => et does not [7] => bytes) // Array ([0] => s [1] => ss see gf [2] => g do not rt [3] => ret immortal)
