Le code ci-dessous est une fonction PHP qui a pour rôle de donner le temps écoulé entre deux dates. Le tableau retourné est composé de 6 champs : years, months, days, hours, minutes, seconds. Ce genre de fonction vous permettra d'afficher des textes du genre : "ceci s'est produit il y a 1 an, 3 mois, 12 jours, 4 heures et 5 minutes, 10 secondes".
Attention, le format d'entrée ($from et $to) est une chaîne de caractères du type YYYY-MM-DD HH:II:SS (format DateTime MYSQL). function DateDiff($from,$to)
{
// $from has to be before $to
