php not loading all of file with file_get_contents and very slow

Well I am having a problem and I don't know if it is the server or php or what.

I have this code that restyles the google calendar with my own css for my webpage.  
The code used to work and now it just kind of stopped.  Basically now the page acts like it is loading for a minute then only displays part of the page.  

My code reads the html in and replaces the css lines and hyperlinks with ones to my page.  But the problem is that it stops reading after so many lines and just prints that to the screen.

But I tested this on my server at work and it works fine loads in 2 secs and displays everything correctly.  
But on my godaddy server it doesn't work so great anymore.

Here is my code.

$stylesheet = 'http://rlchome.org/googlecal/googlecal.css';



/* Default URL

 * This is the embeddable public address for the calendar.  If this value is an

 * empty string, then the script will return a blank page if a valid query

 * string is not submitted. This URL will typically be of the form

 *

 *   http://www.google.com/calendar/embed?src=user%40domain.tld

 *

 * where user@domain.tld is a valid Google Calendar account

 */



$url = "http://www.google.com/calendar/embed?src=brenda%40churchthatcares.org&chrome=NAVIGATION&mode=MONTH&height=900";
//print $url;

// Request the calendar

$buffer = file_get_contents($url);

// Fix hrefs, image sources, and stylesheet

$pattern = '/(href="render)/';

$replacement = 'href="http://www.google.com/calendar/render';

$buffer = preg_replace($pattern, $replacement, $buffer);



$pattern = '/(href="event)/';

$replacement = 'href="http://www.google.com/calendar/event';

$buffer = preg_replace($pattern, $replacement, $buffer);



$pattern = '/(http:\/\/www.google.com\/calendar\/embed)/';

$replacement = 'cal.php';

$buffer = preg_replace($pattern, $replacement, $buffer);



$pattern = '/(src="images)/';

$replacement = 'src="http://rlchome.org/googlecal/images';

$buffer = preg_replace($pattern, $replacement, $buffer);



$pattern = '/(<link.*>)/';

$replacement = '<link rel="stylesheet" type="text/css" href="' . $stylesheet . '" />';

$buffer = preg_replace($pattern, $replacement, $buffer);



// display the calendar

print $buffer;



Also I have tried replaceing the file get conents with this.  No difference.

$fd = fopen ($url, "r");

while (!feof ($fd))

    $buffer .= fread($fd, 8192);

fclose ($fd);



Here is the page. I have tried php4 and 5 both do the same thing.  
http://rlchome.org/googlecal/cal.php


So any help would be appreciated.  I am stuck on this one.
