PHP Regex - Exploding 2 string dates in a single string-CodePudding

I have a date field that looks like the following:

$exampleOne = 'Sep 04-08';
$exampleTwo = 'Sep 29-Oct 01';

How can I separate them to become:

$exampleOneResult = {'Sep 04', 'Sep 08'};
$exampleTwoResult = {'Sep 29', 'Oct 01'};

I was thinking to make a loop of splitting '-' first, then splitting ' ' second, but I think that would be too resource heavy?

CodePudding user response：

Split at the dash for from and to. And then check for the second value and supply if missing.

Doing such logic is not resource heavy. Why using a regex for such a simple thing?

This example is for PHP8

$exampleOne = 'Sep 04-08';
$exampleTwo = 'Sep 29-Oct 01';

print_r(parseDateRange($exampleOne));
print_r(parseDateRange($exampleTwo));

function parseDateRange($dateRange): array {
    [$from, $to] = explode('-', $dateRange);
    [$month] = explode(' ', $from);
    if(!str_contains($to, ' ')) {
        $to = "$month $to";
    }

    return [$from, $to];
}

prints

Array
(
    [0] => Sep 04
    [1] => Sep 08
)
Array
(
    [0] => Sep 29
    [1] => Oct 01
)
