PHP convert string to array

Question

How can I convert a string to an array? For instance, I have this string:

$str = 'abcdef';

And I want to get:

array(6) {
  [0]=>
  string(1) "a"
  [1]=>
  string(1) "b"
  [2]=>
  string(1) "c"
  [3]=>
  string(1) "d"
  [4]=>
  string(1) "e"
  [5]=>
  string(1) "f"
}

Answer 1

Use str_split http://www.php.net/manual/en/function.str-split.php

Answer 2

You can loop through your string and return each character or a set of characters using substr in php. Below is a simple loop.

$str = 'abcdef';
$arr = Array();

for($i=0;$i<strlen($str);$i++){
    $arr[$i] = substr($str,$i,1);
}

/*
OUTPUT:
$arr[0] = 'a';
$arr[1] = 'b';
$arr[2] = 'c';
$arr[3] = 'd';
$arr[4] = 'e';
$arr[5] = 'f';
*/
