How Can I Parse Dates Before 1970 in PHP?

Parsing Dates Prior to 1970 using strtotime()

In PHP, the strtotime() function is commonly used to parse date strings into timestamps. However, it's crucial to note that this function has a limited range, only accommodating dates from January 1, 1970, onward. This can pose a challenge when dealing with dates prior to 1970.

Workarounds

If you're working with PHP versions prior to 5.1.0 and encountering range limitations on certain operating systems, upgrading to a later version of PHP may resolve the issue.

Using DateTime Objects

For handling dates outside the limited range supported by strtotime(), consider using PHP's DateTime objects. These objects offer greater flexibility and can work with a much wider range of dates.

Procedural Approach

$date = date_create($row['value']);
if (!$date) {
    $e = date_get_last_errors();
    foreach ($e['errors'] as $error) {
        echo "$error\n";
    }
    exit(1);
}

echo date_format($date, "F j, Y");

OOP Approach

try {
    $date = new DateTime($row['value']);
} catch (Exception $e) {
    echo $e->getMessage();
    exit(1);
}

echo $date->format("F j, Y");

By utilizing DateTime objects, you can effectively parse and manipulate dates beyond the limitations of strtotime() and handle a wider range of date values.
