shouldn't there be a "." in there after the closing ) to the function?


echo " <location>" . get_link(".$videoinfo[$i]['url'].")."</location>\n";

And what's with passing the text ".$videoinfo[$i]['url']."?

Try this....

echo " <location>" . get_link($videoinfo[$i]['url'])."</location>\n";

Thnaks for your help. The value that i am passing is youtube url link and the function finds out the direct flv link which i need.

Since the script takes too much time to process i get the follwoing error. I need to call the function 100 times and construct the xml but i keep getting error. could you tell me how to over come this problem this problem?Thanks

The following tags were not closed: playlist, trackList, track. Error processing resource 'http://localhost/list...

<b>Fatal error</b>: Maximum execution time of 30 seconds exceeded in <b>\xml2.php</b> on line <b>94</b><br />



could you also tell me how to call same function and this time send it
mysql url value ? I tried the following but i got empty value :


echo " <location>" . get_link($row["url"])."</location>\n";

There is nothing wrong with while loop since the follwing is pulling title from db:


echo " <title>" . $row["title"] . "</title>\n";






......

// print the random numbers
while($row = @mysql_fetch_array($result)) {

echo " <track>\n";
echo " <title>" . $row["title"] . "</title>\n";
echo " <creator>By me</creator>\n";
//echo " <location>" . $videoinfo[$i]['url'] . ".flv</location>\n";
echo " <location>" . get_link($row["url"])."</location>\n";

echo " </track>\n";



}
// .. and last we add the closing tags
echo " </trackList>\n";
echo "</playlist>\n";

does it work when you comment out the location line?

Yes it works when i comment out the location line.

[techgnome]

What happens when you comment out this line?

$url = get_headers($url);

i tried that and i get this in the screen :

output:.flv

No xml and no error!!! That function is not written by me. i found it from a website. i even tried to make the script running time to unlimited but didn't work!!

[techgnome]

Well, I think there's two things here.... get_headers is the reason for the timeout issues you are getting.... it's taking too long to get the headers. There may also be a problem with what you are doing with that header info when you get it back.

But I'm also no expert in PHP either...
