Ejemplo

El siguiente ejemplo demuestra date_parse_from_format () con formatos relativos -

<?php
   print_r(date_parse_from_format("Y-m-d", "2009-18-18-+52 week +25 hour"));
   print("\n");
   print_r(date_parse_from_format("Y-m-d", "1990-06-06 +52 week +25 hour"));
?>

Esto producirá el siguiente resultado:

Array
