str_split

(PHP 5)

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
			)
