file_get_contents .. display error message if no connect

i think this is an easy one, but I can't get it working.  im using something similar to below to grab data from other sites, what I want to do is in case that site is down or unreachable for some reason .. i want to display a nice error message like 'Data not available' or something like that ...

file_get_contents("http://website.html");

any help?  thanks

you should be able to do something simple like

$gc = file_get_contents("http://website.html");
if (!$gc) {
 echo "data does not exist";
}

file_get_contents returns false if it fails so you can use a simple if statement as shown above to check if it was successful or not, obviously !$gc means not $gc (or in other words if $gc returns false).

you could always use alternative methods such as

if (!fopen("http://www.example.com/", "r") {
  echo "data does not exist";
}

or even a slightly more advanced mthod using fsockopen (http://www.php.net/manual/en/function.fsockopen.php) but the first suggestion should work fine.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

thanks for the response.

I tried that and, while it works ... it still dispalys the 'Connection refused ' error if the source is not available.  here is my code below

<?php

$zzz = file_get_contents("http://www5.playnet.com/bv/wwiiol/axis_playnow.jsp");
$zzz = str_replace("<table width=\"100%\" border=\"0\" cellspacing=\"0\">","",$zzz);
$zzz = str_replace("<font face=\"Arial, Helvetica, sans-serif\" size=\"1\">","",$zzz);
$zzz = str_replace("</font>","",$zzz);

$patterns[0] = "/<b>/";
$replacements[0] = "&middot;&nbsp";

$begin = "<!--Axis RDP Archive -->";
$end = "<td align=\"center\" valign=\"middle\"><font face=\"Arial, Helvetica, sans-serif\" size=\"2\">";

$zzz = preg_replace("'<html[^>]*?>.*?$begin'si", $end, $zzz);
$zzz = preg_replace("'<\/table[^>]*?>.*?<\/html>'si", '', $zzz);
$zzz = preg_replace($patterns, $replacements, $zzz);

?>

<html>
<head>
<title>Allied RDP Brief</title>
<link rel="stylesheet" href="stats.css" type="text/css">
</head>
<body bgcolor="#CCCCCC" text="#000000" topmargin="0" bottommargin="0" leftmargin="0" marginwidth="0" marginheight="0">
<table width="350" class="text1" bgcolor="#CCCCCC"><tr><td class="text1" valign="middle" align="left" bgcolor="#CCCCCC"><u><b><em>Axis RDP Brief</em></b></u></td></tr>
<?php if (!$zzz) {
 echo "Data not available";
} else {
?>
<list>
<?php echo "$zzz";
}
?>

</td></tr></table>
</body>
</html>

i presume you mean you just want to hide the error (which is as much as you can do)

just add the @ operator in front of the function to supress the error

ie.

$zzz = @file_get_contents("http://www5.playnet.com/bv/wwiiol/axis_playnow.jsp");
