How to determine if value is a date in PHP

Question

I am working with arrays of values in PHP. Some of these values may include a date in various string formats.

I need to convert dates in multiple formats to their numeri

Answer 1

Extrapolating from http://au1.php.net/checkdate#113205 ; just change the $formats array to all the formats you want to check.

public function convertDate($value) {

    $formats = ['M d, Y', 'Y-m-d'];
    foreach($formats as $f) {
        $d = DateTime::createFromFormat($f, $value);
        $is_date = $d && $d->format($f) === $value;

        if ( true == $is_date ) break;
    }

    return $is_date;

}
