STR_SPLIT(3) 1 STR_SPLIT(3)
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
as the first (and only) array element.
EXAMPLES
Example #1
Example uses of str_split(3)
<?php
$str = "Hello Friend";
$arr1 = str_split($str);
$arr2 = str_split($str, 3);
print_r($arr1);
print_r($arr2);
?>

Array

[0] => H
[1] => e
[2] => l

[4] => o
[5] =>
[6] => F
