execute/read back from remote script

[Anon]

Since my server/host does not allow the use of ping, how can I call a php scipt from another server, have it execute and then read back it's output ?

It would go something like this:
run from cron: home/test.php
calls/executes http://domain.com/tested.php

tested.php: upon execution would query it's datbase & get $result.
$name=test;
$result = mysql_query("select Name from Names where Name='$name'");

Then I want test.php to read $result, if no result send email to me.
if (empty($result) or $result == 0) {
mail("to myself","DB error", "result: $result", "FROM: me$netzero.net");
} else {
success=do nothing;
}

What do you think ?
Thanks,
Peter

I would have it just call the file from another server.

ie.

$url = "http://www.whateveritis.com/ping.php";

$fp = fopen($url);
while (!feof ($fd))
{
$result .= fgets($fd, 4096);
}
flcose($fp);
echo $result;

I think thats what your looking for.

Hi Joe,

I'm already doing that and it only tells me that the file can be read and the server is reachable.
If I can make the remote script query it's database and then read back the result, that would tell me that the PHP and Mysql are running ok/server is not bogged down or plain 100% down !

on top of that I could at some timing code:

<?
$Begin=mktime();

call external script, execute query
read the $result variable 0 or 1

$End = mktime();
$diff=$End - $Begin;

if($result == 0 or $diff > 60) {
mail( send email message )
}

Perhaps there is an easire way to go about it ?!
