str_split

(PHP 5)

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()

 
$str = "Hello Friend";
 
$arr1 = str_split($str);
$arr2 = str_split($str, 3);
 
print_r($arr1);
print_r($arr2);

Output may look like:

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