How to format a string with leading zeros?
A quick reminder:
How do I pad a string so that a number or string gets leading zeros?
Answer:
By using sprintf:
my $number = 123;
$number = sprintf(”%07d”, $number);
print $number;
Output: “0000123″
after the %: “0″ is the character to add, <number>d is the amount of digits (that’s why it’s “d”) to add. See the documentation for sprintf.
