Question

We have a “potential” 7 digit number that we need to break into 7 separate variables. If it is a 4 digit number, then the other 3 digits should be empty. As an example:

$total = 12345 

$var1 = ""
$var2 = ""
$var3 = "1"
$var4 = "2"
$var5 = "3"
$var6 = "4"
$var7 = "5"

Anyone have any ideas on the best way to do this?

Thanks in advance.

Answer 1

Split, then pad:

$a = 123456;
$arr = array_pad(str_split($a), -7, "");

See output.

And if you absolutely need 7 variables:

$a = 123456;
$arr = array_pad(str_split($a), -7, "");
$i = 1;
foreach($arr as $s)
    ${"var".$i++} = $s;

But I strongly suggest using an array.
