MySQL DATETIME Helper

Category:Helper::Community | Category:Helper::Date | Category:Helper::Database

To enhance CI's date helper with MySQL DATETIME / DATE functionality just create [b]date_helper.php[/b] in your application’s helpers directory, paste the [b]original date_helper.php[/b] in (to keep its functionality) and then add the following code:

[code]/**

• Convert MySQL's DATE (YYYY-MM-DD) or DATETIME (YYYY-MM-DD hh:mm:ss) to timestamp

• Returns the timestamp equivalent of a given DATE/DATETIME

• @todo add regex to validate given datetime

• @author Clemens Kofler clemens.kofler@chello.at

• @access public

• @return integer */ function mysqldatetime_to_timestamp($datetime = "") { // function is only applicable for valid MySQL DATETIME (19 characters) and DATE (10 characters) $l = strlen($datetime); if(!($l == 10 || $l == 19)) return 0;

  // $date = $datetime; $hours = 0; $minutes = 0; $seconds = 0;

  // DATETIME only if($l == 19) { list($date, $time) = explode(" ", $datetime); list($hours, $minutes, $seconds) = explode(":", $time); }

  list($year, $month, $day) = explode("-", $date);

  return mktime($hours, $minutes, $seconds, $month, $day, $year); }

/**

• @access public
• @return integer */ function mysqldatetime_to_date($datetime = "", $format = "d.m.Y, H:i:s") { return date($format, mysqldatetime_to_timestamp($datetime)); }

/**

• @return string */ function timestamp_to_mysqldatetime($timestamp = "", $datetime = true) { if(empty($timestamp) || !is_numeric($timestamp)) $timestamp = time();

  return ($datetime) ? date("Y-m-d H:i:s", $timestamp) : date("Y-m-d", $timestamp); }[/code]

New functions to enhance still more the CI's date helper with MySQL DATETIME / DATE functionality. The procedures continue being the same ones, just add in your date_helper.php, in your application’s helpers directory, the following code:

[code]/**

/**

  $day = $date[1]; $month = $date[2]; $year = $date[3]; $hour = (empty($date[6])) ? 0 : $date[6]; $min = (empty($date[7])) ? 0 : $date[7]; $sec = (empty($date[9])) ? 0 : $date[9];

  return mktime($hour, $min, $sec, $month, $day, $year); }
