                                   str_split

   (PHP 5 CVS only)
   str_split --  Convert a string to an array

Description

   array str_split ( string string [, int split_length])

   Converts a string to an array. If the optional split_length parameter
   is specified, the returned array will be broken down into chunks with
   each being split_length in length, otherwise each chunk will be one
   character in length.

   FALSE is returned if split_length is less than 1. If the split_length
   length exceeds the length of string, the entire string is returned as
   the first (and only) array element.

   Example 1. Example uses of str_split()
   <?php
   $str = "Hello Friend";
   $arr1 = str_split($str);
   $arr2 = str_split($str, 3);
   print_r($arr1);
   print_r($arr2);
   ?>

   Output may look like:
Array
(
    [0] => H
    [1] => e
    [2] => l
    [3] => l
    [4] => o
    [5] =>
    [6] => F
    [7] => r
    [8] => i
    [9] => e
    [10] => n
    [11] => d
)

Array
(
    [0] => Hel
    [1] => lo
    [2] => Fri
    [3] => end
)

   Example 2. Examples related to str_split()
   <?php
   $str = "Hello Friend";
   echo $str{0};  // H
   echo $str{8};  // i
   // Creates: array('H','e','l','l','o',' ','F','r','i','e','n','d')
   $arr1 = preg_split('//', $str, -1, PREG_SPLIT_NO_EMPTY);
   ?>
