Tri des résultats d'un script de miniatures PHP

J'ai trouvé le script PHP suivant sur le net qui prend un répertoire d'images et crée des miniatures. Cette partie fonctionne très bien, attendez que j'ai remarqué que le tri est désactivé. Le mieux que je peux dire est qu'il utilise des noms de fichiers, je voudrais utiliser la date de création que je suis en train de trier un répertoire d'images créées à partir d'une caméra de sécurité.Tri des résultats d'un script de miniatures PHP

Toute entrée et un peu (ok, beaucoup) de direction serait génial car je n'ai pas beaucoup d'expérience PHP, mais je peux me déplacer un peu.

Merci encore pour l'aide!

J'ai ajouté un tri très sale (pas efficace). Passez la ligne ci-dessous à SORT_DESC ou SORT_ASC dans le code pour trier par ordre décroissant ou croissant.

arraySortByColumn($exifData, 'time', SORT_DESC);
