PHP file_get_contents() not reading entire page

Hi. Im trying to write a web page parser which will extract weather data from a web site. The URL is : “http://www.accuweather.com/adcbin/public/inthbh_local.asp?partner=accuweather&metric=1&whend=1&whent=8”

I have encountered a problem where the function file_get_contents(URL) does not read the entire web page. I have even tried using fopen() and it still always gets only half of the page. Does anyone know why this is happening?
