I need to break an integer where each digit in this integer is to be an element in an array like this:
$x = 123;
var_dump($x_array);
Will out put something like this:
Array
(
[0] => 1
[1] => 2
[2] => 3
)
Thanks.

print_r(str_split($x));
Array ( [0] => 1 [1] => 2 [2] => 3 )
Don't forget the "php" tag next time!

Thanks to Graphox I got this solution: $x= 1234; $array = array(); $x = str_split($x); foreach($x as $number){ $number = intval($number); array_push($array,$number); } var_dump($x); var_dump($array); but after some work and the help of Ayyash I got this: $x = 1234; $y = 1; $array = array(); while($y){ $remainder = $x % 10 ; array_push($array, $remainder); $x = $x - $remainder; $x = $x /10; if($x == 0){ $y = 0; } }
(1) Array of digits as strings:
$x_array = str_split($x);
var_dump($x_array);
0 => string '1' (length=1)
1 => string '2' (length=1)
2 => string '3' (length=1)
(2) Array of digits as integers:
$x_array = array_map('intval', str_split($x));
var_dump($x_array);
0 => int 1
1 => int 2
2 => int 3
