PHP DateTime __construct() Failed to parse time string (xxxxxxxx) at position x

Question

I had this construction error when trying to creating a new DateTime object using a timestamp:

Exception: DateTime::_construct(): Failed to parse

Answer 1

This worked for me.

   /**
     * return date in specific format, given a timestamp.
     *
     * @param  timestamp  $datetime
     * @return string
     */
    public static function showDateString($timestamp)
    {
      if ($timestamp !== NULL) {
        $date = new DateTime();
        $date->setTimestamp(intval($timestamp));
        return $date->format("d-m-Y");
      }
      return '';
    }
