php分手数变量？

Question

有没有办法在没有任何空格的情况下分解指定变量中的值？

例如.

$var = 123456789;

我可以通过爆炸阵列购买来做到这一点,因为没有空间我有困难.

$result = explode("", $var);

$results[0] = $a;
$result[1] = $b;
$result[2] = $c;

等等...

$a would = 1
$b would = 2
$c would = 3

等等...

这可能吗？

这str_split是为了什么.它将隐式将其参数转换为字符串:

$num = 12345;

$arr1 = str_split($num);

print_r($arr1);

输出:

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
)
