PHP Split string into array like explode with no delimiter

Question

I have a string such as       0123456789    and need to split EACH character into an array   I for the hell of it tried   explode      123545789      But it gave me the obvious  Warning  No delimiter defined in explode      How would I come across this  I can t see any method off hand  especially just a function

Here is an example that works with multibyte ( UTF-8 ) strings.

$str = 'äbcd';

// PHP 5.4.8 allows null as the third argument of mb_strpos() function
do {
    $arr[] = mb_substr( $str, 0, 1, 'utf-8' );
} while ( $str = mb_substr( $str, 1, mb_strlen( $str ), 'utf-8' ) );

It can be also done with preg_split() ( preg_split( '//u', $str, null, PREG_SPLIT_NO_EMPTY ) ), but unlike the above example, that runs almost as fast regardless of the size of the string, preg_split() is fast with small strings, but a lot slower with large ones.

array   str split   string      will actuall work pretty fine  BUT if you want to preserve the special characters in that string  and you want to do some manipulation with them  THAN I would use  do        array     mb substr   string  0  1   utf-8       while    string   mb substr   string  1  mb strlen   string     utf-8         because for some of mine personal uses  it has been shown to be more reliable when there is an issue with special characters
