Tijden veranderen
Verjaardags script
Gebruikers kunnen hun verjaardag zelf toevoegen.
Op de site zou je dan kunnen zien wie die dag jarig is en wie de komende 7 dagen. Tliefst zonder gebruik van MySQL
Je moet dan bij iedere bezoeker een .txt inlezen, per regel in een array. Dan per item kijken naar de datum en dat vervolgens displayen.
Je zou het met een cronjob 1x per dag kunnen doen. Maar eigenlijk zou ik het advies geven om hier niet aan te beginnen zonder database.
Dit werkt met interne array. Ma tzou moeten werken zodat gebruikers via een formulier ofzo hun namen zlef in de array kunnen steken.
