cgi error

[jackvull]

Hi

I have a script which attempts to run an external script on another server. For testing reasons it's 127.0.0.1

$url = "http://127.0.0.1/htdocs/UpdateCount.php?aID=".$aID;
$needle = 'Count:';
$contents = file_get_contents($url);
echo $contents;
if(strpos($contents, $needle)!== false) {
echo '<br />found';
} else {
echo '<br />not found';
}

I get the following error when I run it:
The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:

PHP version 4.4.2
IIS win2k

Any ideas why?
I've seen various bug reports for this error but none are related to file_get_contents and I'm not doing anything strange in the external script. It just runs a DB query and echo's it to the page.

Are you sure you don't want the url to be:

$url = "http://127.0.0.1/UpdateCount.php?aID=".$aID;

Also, why don't you execute the query from your own script?

For testing, yeah, it definitely needs the htdocs in there. That's just the way my dev server is.
I've tested that script by using the url directly in a browser and it outputs some data.

The reason I can't use it directly, is that this script (running the file_get_contents) will actually be run on a different server. So, I'm running it on Server 2, it's supposed to retrieve a database value from server 1 and then use that in some of its variables.

I can't access server 1's DB directly cos of their security setup.

I assume that you've tried running the UpdateCount.php script directly from your web browser. And tried a 'hello world' script in place of the script that's using file_get_contents.

I ran the following, and it worked fine under Apache.

<?php

$aID = "0";
$url = "http://localhost/index.php?id=".$aID;
$needle = 'Count:';
$contents = file_get_contents($url);
echo $contents;
if(strpos($contents, $needle)!== false) {
echo '<br />found';
} else {
echo '<br />not found';
}

Yeah, it works fine when I comment out the file_get_contents section. It just echos the url or whatever I get it to do.
It's starnge because even with the cgi error I can see that the external script was accessed because the database fields change.

I'll try it on Apache later and see if that makes a difference.

It seems like it may be a problem with your "remote" script. I would also take a peek there to see if you can identify what's causing this. I'm assuming that this error message came from that script when you received its contents?

Thanks for all the help.
It works fine on apache.
Must have been an IIS problem.
