Database Abstraction Layer for PHP

Use of 64 bit processors and later versions of PHP have effectively made this function obsolete. It may be removed in later releases of ADOdb

float dbObject::unixDate(){
       string $timestamp


The static function unixTimeStamp() Parses the timestamp string $str and returns it in UNIX mktime format (.g. a number indicating the seconds after January 1st, 1970.

It expects the date passed to be in one of the following formats:

  • “Y-m-d, H:i:s” (1970-12-24, 00:00:00)
  • “Y-m-d H:i:s” (1970-12-24 00:00:00)
  • “YmdHis” (19701225000000)
  • “M d Y h:i:s” (Dec 25 1970 00:00:00AM) (SQL Server and Sybase only) (the 3 letter month strings are controlled by a global array, which might need localisation).

For databases that do not support the functionality, the function makes use of ADOdb time handling library.


SQL Server example

 * Connection to SQL Server database assumed
$d = $db::unixDate(strtotime('1920-10-10 00:00:00'));
print $d;
 * returns -1553450400
print date('Y-m-d',$d);
 * Returns the following string: '1920-10-10'
