fsockopen(): unable to connect...

[FreeFall]

Hello,
i am trying to set up a page which tells you if my radio server is online or not.
I have had a word with the people who host my radio, and they said the script works fine, but the host i am on "may block outbound connections.

Can anyone offer any advice on why i get this error:

Warning: fsockopen(): unable to connect to 213.48.102.229:9150 in /home/sosolidp/public_html/radio_stats.php on line 25

Here is some code, line 25 is "$page .= fgets($scfp, 1000);"

$scfp = fsockopen("$scip", $scport, &$errno, &$errstr, 30);
 if(!$scfp) {
  $scsuccs=1;
echo''.$scdef.' is Offline'; 
 }
if($scsuccs!=1){
 fputs($scfp,"GET /admin.cgi?pass=$scpass&mode=viewxml HTTP/1.0\r\nUser-Agent: SHOUTcast Song Status (Mozilla Compatible)\r\n\r\n");
 while(!feof($scfp)) {
 $page .= fgets($scfp, 1000);
 }

FreeFall,

First thing I would suggest you to do is adding error diagnostic. There are quite a few factors to consider when connection can't be established and blocking (or filtering) is only one of them.

Let us know how it goes.

LOL, i have no idea how to do that, i will ask my radio hosts again maybe there is something wrong/another solution :P

Since it looks like you are just trying to connect to a web server, you may want to try using fopen() (or even file()) instead of fscock open. With fopen()/file() you can pass a URL as the file path. Then you can just start fgets()ing, you don't need to start talking HTTP with fputs().

Example:
fopen('http://213.48.102.229:9150/admin.cgi?pass=$scpass&mode=viewxml', 'r');

file() would make it even easier, as it will return just the content of the request (without the headers to parse out) in an array when you simply pass the URL.

if i have $scfp = file($scip, $scport, &$errno, &$errstr, 30); i get:
Warning: file() expects at most 2 parameters, 5 given in /home/sosolidp/public_html/radio_stats.php on line 25

If i use fopen i get:
Warning: fopen() expects at most 4 parameters, 5 given

If you cannot already tell, i know nothing about PHP

Jason,

That might work, but HTTP protocol also allows to send data in 'chunks', in which case the actual data could be mixed with HTTP headers when you just read everything.

Besides, we dont know why fsockopen doesn't work, what would be the point of substituting it with fopen()?
Even if there is a problem with fsockopen, checking the error first looks like the best course of action time-wise.

FreeFall:
Add the following after the first line (with fsockopen):

print "Error code: $errno, Error string: $errstr<BR>\n"; 

then try to run the script again and let us know what response you get.

All you need is

$scfp = file('<url as above>'); {or}
$scfp = fopen('<url as above>', 'r');

If you use file() and it works, $scfp will be an array that will contain whatever the server r eturns. You should then use this command to condence it into a single string as you would get with the method you posted in your sample:

$page = implode('', $scfp);

You'll probably want to comment out (recommended) or remove the block of code starting with the fsockopen() call and likely ending with fclose() to avoid any problems. Then insert the above two lines in their place.

With fopen(), $scfp will contain a file handle the same way that an fsockopen() call would. You'll want to comment out (again, recommended) or remove the fsockopen() and fputs() lines, but leave the fgets() and fclose() lines alone. In this case, $page will contain both the content that the site returns and the headers. I'd suspect that farther down in your code there are lines to handle this, so this might be the better route to try.

Hope this helps.
