$server = "www.example.com";
$port    = 80;

$fp = @fsockopen($server, $port, $errno, $errstr, 5);

  echo "down";
} else {

thx, i hope this works

how could you make it so you could input the $server and $port from the webpage?

[drew010]

since all public webservers run on port 80, its not really necessary to grab the port but you can use a form to get the server.

<?php
if (isset($_GET['server'])) { 
  $fp = @fsockopen($_GET['server'], 80, $errno, $errstr, 5);
  if (!$fp) {
    echo "Server is down.";
  } else {
    echo "Server is up.";
  }
}
?>
<br /><br />
<form method="GET">
<input type="text" name="server"><br />
<input type="submit" value="Query Server">
</form>

<form method="GET">
Server/IP: <input type="text" name="server"><br />
<style="text-indent: -0.5in; margin-left: 0.5in">Port:<span> <input type="text" add value="80" name="port"><br />
<input type="submit" value="Check">
</form>
<?php
if (isset($GET['server']) && isset($GET['port'])){
$fp = @fsockopen($GET['server'], 80, $errno, $errstr, 5);
if (!$fp) {
echo "<b>{$GET['server']}:{$GET['port']}</b> is down.";
} else {
echo "<b>{$GET['server']}:{$_GET['port']}</b> is up.";
}
