Php string and Chinese Character splitting method-PHP source code

Ec (2); if you use the php tutorial function & ldquo; str_split & rdquo; to separate it, garbled characters will appear, because the length of Chinese characters is different from that of English characters. However, we can create a new function to convert characters into ascii values first, then correctly split the Chinese strings by judging the length of different characters, store the results into an array, and then use the php function & ldquo; join & rdquo; insert percent sign between characters & lt ;?

If you use the php tutorial function "str_split" to separate the strings, garbled characters will appear, because the length of Chinese characters is different from that of English characters. However, we can create a new function to convert characters into ascii values first, and then divide the Chinese strings correctly by judging the length of different characters, and store the results into arrays, finally, use the php function "join" to insert a percent sign between characters.

Function str_split_utf8 ($ str ){
$ Split = 1;
$ Array = array ();
For ($ I = 0; $ I $ Value = ord ($ str [$ I]);
If ($ value & gt; 127 ){
If ($ value >=192 & $ value <= 223) $ split = 2;
Elseif ($ value >=224 & $ value <= 239) $ split = 3;
Elseif ($ value >=240 & $ value <= 247) $ split = 4;
} Else {
$ Split = 1;
}
$ Key = null;
For ($ j = 0; $ j <$ split; $ j ++, $ I ++ ){
$ Key. = $ str [$ I];
}
Array_push ($ array, $ key );
}
Return $ array;
}
$ String = "www.111cn.net ";
$ Arr1 = str_split_utf8 ($ string );
Echo join ("%", $ arr1 );
?>

Method 2

$ Str = "a poly tutorial Network: http://www.111cn.net ";
Function mbstringtoarray ($ str, $ charset ){
$ Strlen = mb_strlen ($ str );
While ($ strlen ){
$ Array [] = mb_substr ($ str, 0, 1, $ charset );
$ Str = mb_substr ($ str, 1, $ strlen, $ charset );
$ Strlen = mb_strlen ($ str );
}
Return $ array;
}
$ Arr = mbstringtoarray ($ str, "gb2312 ");
?>

Note:

1. The $ charset variable is webpage encoding, for example, "gb2312" or "UTF-8 ";

2. method 1 requires that the server must enable the mbstring. dll extension. Otherwise, the code execution is incorrect. Therefore, you can consider using the second method for your friends who use the VM.

Method 2:

Function str_to_arr ($ str ){
$ L = strlen ($ str );
For ($ I = 0; $ I <$ l; $ I ++ ){
$ Arr [] = ord ($ str [$ I]) & gt; 127? $ Str [$ I]. $ str [++ $ I]: $ str [$ I];
}
Return $ arr;
}
$ Arr = str_to_arr ($ str );
?>
