title: PHP Cron Manager / Scheduler
body: <p>We work on projects in which we have several cron jobs. One that run every 30 mins , one that runs every midnight, one that runs at 2:00 PM etc. Now instead of setting individual cron jobs every time, is there some sort of PHP cron manager class, which I can schedule to run say every 1 minute and using that manager I can fire other crons/scripts at specific time or intervals. We are planning of developing one like this, but I was looking for existing options before we start, but couldn't find any. Any suggestions?</p>
  
  <p>Thanks</p>
