load_url

I have a php file that stops running in the middle if there is an unsuccessful load_url() function call. Is there a way to make the rest of the code execute even if the url can't be reached? Thanks


code
...
$url = "http://www.someurlthatistemporarilydown.com/submit.php";
$result = load_url($url);

//if the url is temporarily down then the code stops and the rest of the code doesn't execute
...
rest of code





Here is the load_url function that is declared before the call to it.
require("http.php");

function load_url( $url ) {
$returnvalue = "";
set_time_limit(0);

$http=new http_class;

$http->timeout=0;
$http->data_timeout=0;
$http->debug=0;
$http->html_debug=0;
$http->follow_redirect=0;
$http->user_agent="Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)";

$error=$http->GetRequestArguments($url,$arguments);

$error=$http->Open($arguments);
if($error) die($error);

$error=$http->SendRequest($arguments);
if($error) die($error);

$headers=array();
$error=$http->ReadReplyHeaders(&$headers);
if($error) die($error);

for(Reset($headers),$header=0;$header<count($headers);Next($headers),$header++) {
$header_name=Key($headers);
if(GetType($headers[$header_name])=="array")
{
for($header_value=0;$header_value<count($headers[$header_name]);$header_value++)
if ($header_name == "location") { return load_url($headers[$header_name][$header_value]); }
}
else
if ($header_name == "location") {
$redir = $headers[$header_name];
$regexp = "http(s?)\:\/\/(.*)\/(.*)";
if(preg_match("/$regexp/siU", $redir, $matches)) {
$url = $redir;
return load_url($url);
} else {
if(preg_match("/$regexp/siU", $url, $matches)) {
$url = "http://".$matches[2].str_replace(" ", "%20", $redir);
return load_url($url);
} else {
return "An Error Has Occurred.";
}
}
}
}

for(;;) {
$error=$http->ReadReplyBody($body,1000);
if ($error!="" || strlen($body)==0)
break;
$returnvalue .= $body;
}
return $returnvalue;
}

If you call the die function, it will stop your script.

You should consider just returning an empty string instead of calling die, when for some reason there was an error.
