you can write simple php script following , run script scheduling in cron job , once script runs, delete cron tab (the script keep runing):

while (true) {     // setup curl request foursquare     // fire curl request , results     // processing     // can put sleep here before again   loops     // here magic break infinite loop - check     // variable database table or ini file , break loop     // if variable set }
