String to array - array with only one index (PHP)

Question

I have this string:

$string = "123456789"

It should become an array:

Array ( [0] => 123 ) Array ( [1] => 456 ) Array ( [2] => 789 )

but I get:

Array ( [0] => 123 ) Array ( [0] => 456 ) Array ( [0] => 789 )

I use loop to get this string:

for ($i=0; $i<$num; $i++)
{
    $string = $tree['a']['b'][$i]['c'];
}

Next I use explode function to get an array. Why I got the array with only one index - zero? What I should do to get:

 Array ( [0] => 123 ) Array ( [1] => 456 ) Array ( [2] => 789 ).

Please help me understand this.

What generates the output you publish here? What is $tree? What is ` $string` ?
I parse xml file. I got data in a tree structure (multi-dimensional Array).

Use str_split($string, 3) to create the array.

	Thanks but I got the same (array with only one index). – Delicja Apr 24 '12 at 7:03
	the function str_split should work `$arr = str_split($string, 3);` – SuperNoob Apr 24 '12 at 7:49
