buildJSON.php

<?php
/* Läser in skjutsar från Skjutsgruppens hemsida, lagrar skjutsar som ännu inte hänt i liftsJSON1.php. Dessa kombineras sedan i combineJSON.php.  Läser in var man ska börja från startLift.txt som är den första giltiga skjutsen förra körningen. Sparar var man slutar i startLift3.txt som sedan läses av buildJSON3.Servern kan inte hantera för många anrop i samma fil, därav uppdelningen i tre. Sannolikt behöver detta utökas till ännu fler, skulle jag tro. 
	
Observera att man behöver fylla i en giltig användares epost och lösenordet i $url-variabeln, f.n. rad 26.
	
Den här filen ska köras först av alla, därefter buildJSON2, buildJSON3, combineJSON och sist facebookboten.
