weather script - displaying dregrees Celsius instead of Fahrenheit

[spirelli]

Hi, I run this script to retrieve weather info from msnbc.com on my hopmepage. However this does only display Farenheit, but I need it in Celsuis. I'm not that great with PHP, so maybe ther is someone who can help me. How can I acheive this?

<?php

if (!$accid) {
	$accid="UKXX1764"; # Your default city location code, please change to your city ACCID code.
}



$url ="http://www.msnbc.com/m/chnk/d/weather_d_src.asp?acid=$accid";

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

/*
$fa = fsockopen("www.msnbc.com", 80, &$num_error, &$str_error, 30);
if(!$fa)
   { print "Weather is not available: $str_error ($num_error)\n"; }
else
{
  fputs($fa,"GET /m/chnk/d/weather_d_src.asp?acid=WRRR HTTP/1.0\n\n"); # Replace WRRR with your city ACID code!
  $answer=fgets($fa,128);

[Mr.Happy]

before your print code, right before:

$temp = ($v_Temp-32)*(5/9); 

Then in the third print line, change $v_Temp to $temp
That should make you good to go.

Thanks a lot Mr. Happy. It works!
Small Problem though: It displays a lot of digests after the dot, for example:
2.7777777777778°C

That's a bit mad. Ideally this should say 3°C. How can this be acheived?

Thanks!!

[Mr.Happy]

 $temp = ($v_Temp-32)*(5/9); 
 $temp = round($temp);
// $temp = round($temp,1) this would display 2.8 as opposed to 3 

Try that.

Hey Mr Happy, you've made me very happy!!
All working great now. Thanks!

No problem glad I could help ^_^
