str_split - Convert a string to an array

SYNOPSIS
       array str_split (string	$string, [int  $split_length = 1])

DESCRIPTION
	Converts a string to an array.

PARAMETERS
	      o $string
		- The input string.

	      o $split_length
		- Maximum length of the chunk.

RETURN VALUES
	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
