php script problem

I copy the php script in the web. I found that it has the following error massage “Warning: file(http://www.hko.gov.hk/textonly/forecast/chinesewx.htm) [function.file]: failed to open stream: HTTP request failed! in /var/www/html/weather1.php on line 18” when I use in my web server.

However, it works if I change the code from “$weatherURL=' http://www.hko.gov.hk/textonly/forecast/chinesewx.htm';” to “$weatherURL=' text.html';” (text.html stored the text in the http://www.hko.gov.hk/textonly/forecast/chinesewx.htm).

Can anyone help me.

<?php

$weatherURL=' http://www.hko.gov.hk/textonly/forecast/chinesewx.htm';

$file=file($weatherURL);
$temperature = $file[15]; //line 15
$temperature = ereg_replace("氣 溫 ： ","","$temperature");
$temperature = ereg_replace(" 度","","$temperature");
$temperature = ereg_replace("\n","","$temperature");

echo $temperature;

?>

 

The problem is that the file() function requires a path within the server.

All you need to do is replace $file=file($weatherURL); with
$file=file_get_contents($weatherURL);

 

The error is still happened.

The error massage is
"Warning: file_get_contents(http://www.hko.gov.hk/textonly/forecast/chinesewx.htm) [function.file-get-contents]: failed to open stream: HTTP request failed! in /var/www/html/weather1.php on line 18"

 

I use allways the php webclient class Snoopy to grap websites. But use the Snoopy class from wordpress, that's better maintenced than the original Snoopy class...

 

I think I see the problem, you need to take out that extra space character at the beginning of the URL. Like so:
$weatherURL = '"http://www.hko.gov.hk/textonly/forecast/chinesewx.htm";

 

Are you sure you have outgoing connections enabled ?

 

I check that the outgoing connections is enabled and I use the code like "$weatherURL = '"http://www.hko.gov.hk/textonly/forecast/chinesewx.htm";". The problem is still happened.

 

If this happens to me I just use curl.

$url="weathersite"
$ch = curl_init();
            $user_agent = "Mozilla/4.0 (compatible; MSIE 5.01; ".
                          "Windows NT 5.0)";
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_USERAGENT, $user_agent);
            curl_setopt( $ch, CURLOPT_HTTPGET, 1 );
            curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
            curl_setopt( $ch, CURLOPT_FOLLOWLOCATION , 1 );
            curl_setopt( $ch, CURLOPT_FOLLOWLOCATION , 1 );
            curl_setopt( $ch, CURLOPT_URL, $url );
            curl_setopt( $ch, CURLOPT_REFERER, $ref );
            curl_setopt ($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
            $html = curl_exec($ch);
            curl_close($ch);

PHP:

Then parse $html
