mb_splitSplit multibyte string using regular expression

Description

array mb_split ( string $pattern , string $string [, int $limit = -1 ] )

Split a multibyte string using regular expression pattern and returns the result as an array.

Parameters

pattern

The regular expression pattern.

string

The string being split.

limit
If optional parameter limit is specified, it will be split in limit elements as maximum.

I figure most people will want a simple way to break-up a multibyte string into its individual characters. Here's a function I'm using to do that. Change UTF-8 to your chosen encoding method.

<?php
function mbStringToArray ($string) {
   
$strlen mb_strlen($string);
    while (
$strlen) {
       
$array[] = mb_substr($string,0,1,"UTF-8");
       
$string mb_substr($string,1,$strlen,"UTF-8");
       
$strlen mb_strlen($string);
    }
    return 
$array;
}
?>

We are talking about Multi Byte ( e.g. UTF-8) strings here, so preg_split will fail for the following string: 

'Weiße Rosen sind nicht grün!'

And because I didn't find a regex to simulate a str_split I optimized the first solution from adjwilli a bit:

<?php
$string 
'Weiße Rosen sind nicht grün!'
$stop   mb_strlen$string);
$result = array();

for( 
$idx 0$idx $stop$idx++)
{
   
$result[] = mb_substr$string$idx1);
}
?>

Here is an example with adjwilli's function:

<?php
mb_internal_encoding
'UTF-8');
mb_regex_encoding'UTF-8'); 

function 
mbStringToArray
$string
)
{
 
$stop   mb_strlen$string);
 
$result = array();

  for( 
$idx 0$idx $stop$idx++)
  {
     
$result[] = mb_substr$string$idx1);
  }

  return 
$result;
}

echo 
'<pre>'PHP_EOL
print_rmbStringToArray'Weiße Rosen sind nicht grün!'true)), PHP_EOL,
'</pre>'
?>

Let me know [by personal email], if someone found a regex to simulate a str_split with mb_split.

an other way to str_split multibyte string:
<?php
$s
='әӘөүҗңһ';

//$temp_s=iconv('UTF-8','UTF-16',$s);
$temp_s=mb_convert_encoding($s,'UTF-16','UTF-8');
$temp_a=str_split($temp_s,4);
$temp_a_len=count($temp_a);
for(
$i=0;$i<$temp_a_len;$i++){
   
//$temp_a[$i]=iconv('UTF-16','UTF-8',$temp_a[$i]);
   
$temp_a[$i]=mb_convert_encoding($temp_a[$i],'UTF-8','UTF-16');
}

echo(
'<pre>');
print_r($temp_a);
echo(
'</pre>');

//also possible to directly use UTF-16:
define('SLS',mb_convert_encoding('/','UTF-16'));
$temp_s=mb_convert_encoding($s,'UTF-16','UTF-8');
$temp_a=str_split($temp_s,4);
$temp_s=implode(SLS,$temp_a);
$temp_s=mb_convert_encoding($temp_s,'UTF-8','UTF-16');
echo(
$temp_s);
?>

In addition to Sezer Yalcin's tip.

This function splits a multibyte string into an array of characters. Comparable to str_split().

<?php
function mb_str_split$string ) {
   
# Split at all position not after the start: ^
    # and not before the end: $
   
return preg_split('/(?<!^)(?!$)/u'$string );
}

$string   '火车票';
$charlist mb_str_split$string );

print_r$charlist );
?>

# Prints:
Array
(
    [0] => 火
    [1] => 车
    [2] => 票
)

The $pattern argument doesn't use /pattern/ delimiters, unlike other regex functions such as preg_match.

<?php
   
# Works. No slashes around the /pattern/
   
print_rmb_split("\s""hello world") );
   Array (
      [
0] => hello
     
[1] => world
   
)

   
# Doesn't work:
   
print_rmb_split("/\s/""hello world") );
   Array (
      [
0] => hello world
   
)
?>

To split an string like this: "日、に、本、ほん、語、ご" using the "、" delimiter i used:

     $v = mb_split('、',"日、に、本、ほん、語、ご");

but didn't work.

The solution was to set this before:

       mb_regex_encoding('UTF-8');
      mb_internal_encoding("UTF-8"); 
     $v = mb_split('、',"日、に、本、ほん、語、ご");

and now it's working:

Array
(
    [0] => 日
    [1] => に
    [2] => 本
    [3] => ほん
    [4] => 語
    [5] => ご
)

a (simpler) way to extract all characters from a UTF-8 string to array with a single call to a built-in function:

<?php
  $str 
'Ма-
руся'
;
 
print_r(preg_split('//u'$strnullPREG_SPLIT_NO_EMPTY));
?>

Output:

Array
(
    [0] => М
    [1] => а
    [2] => -
    [3] => 

    [4] => р
    [5] => у
    [6] => с
    [7] => я
)

I agree that some people might want a mb_explode('', $string);

this is my solution for it:

<?php

$string 
'Hallöle';

$array array_map(function ($i) use ($string) { 
    return 
mb_substr($string$i1); 
}, 
range(0mb_strlen($string) -1));

expect($array)->toEqual(['H''a''l''l''ö''l''e']);

?>
