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

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
<?php
$zzz = file_get_contents("http://www5.playnet.com/bv/wwiiol/axis_playnow.jsp");
$zzz = str_replace("<table width=\"100%\" border=\"0\" cellspacing=\"0\">","",$zz
$zzz = str_replace("<font face=\"Arial, Helvetica, sans-serif\" size=\"1\">","",$zzz);
$zzz = str_replace("</font>","",$
$patterns[0] = "/<b>/";
$replacements[0] = "· ";
$begin = "<!--Axis RDP Archive -->";
$end = "<td align=\"center\" valign=\"middle\"><font face=\"Arial, Helvetica, sans-serif\" size=\"2\">";
$zzz = preg_replace("'<html[^>]*?
$zzz = preg_replace("'<\/table[^>
$zzz = preg_replace($patterns, $replacements, $zzz);
?>
