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.

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


$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);


<title>Allied RDP Brief</title>
<link rel="stylesheet" href="stats.css" type="text/css">
<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 (!$zzz) {
 echo "Data not available";
} else {
<?php echo "$zzz";

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
