Question... by Eddie on 07-02-2007 at 12:25 PM
Hello guys, another web based question 
With the code that collects a number from a certain website, is constantly failing when the connection that site isnt working...here is the code.
code:Is there a way i can make it so that when the website it collects data from isnt working it just displays "Some" or something, because the "die blablabla" doesnt seem to do that
$data = file_get_contents("http://www.habbo.com.au/habbo_count_xml.action") or die("Could not get data");
$usercount = preg_replace("/<usercount>([0-9]+)<\\/usercount>/", "\\1", $data);
echo $data;

first, you have to remove the die message. then, put if statements around any place that uses the contents of $data to see if it is null or empty

What MeEtc means:
code:
$data = file_get_contents("http://www.habbo.com.au/habbo_count_xml.action");
if ($data)
{
$usercount = preg_replace("/<usercount>([0-9]+)<\\/usercount>/", "\\1", $data);
// and all the other stuff you want to do with $data
echo $data;
}
else
{
echo("Unable to retreive data");
}

code:Shows the number of users.
$data = @file_get_contents("http://www.habbo.com.au/habbo_count_xml.action") or die("Could not get data");
$usercount = preg_replace("/<usercount>([0-9]+)<\\/usercount>/", "\\1", $data);
echo $data;
code:(Notice the aa at the end of the URL, bumming it up). This works as it should for me. (ie, Could not get data is sent to the browser).
$data = @file_get_contents("http://www.habbo.com.au/habbo_count_xml.actionaa") or die("Could not get data");
$usercount = preg_replace("/<usercount>([0-9]+)<\\/usercount>/", "\\1", $data);
echo $data;
Notice the @ in front of file_get_contents - this disables warnings. (Edit: For that function).
You could also do (as the last line):
echo ($data) ? $data : "No Data";
