Hello, coders! 💻

How about a quick little challenge?

How would you left pad zeros to month and day parts of this stringified date 2022-5-3 so that we get 2022-05-03?

Click for a solution using PHP

$input = '2022-5-3';
$output = vsprintf('%04d-%02d-%02d', explode('-', $input));

vsprintf takes an array as input so we do that using explode and then we specify the output format.

Happy coding! ⌨️
