Question

This site has been up for several months now and has been working fine. I have a PHP page that creates an invoice from data in the url (e.g. viewinvoice.php?id=250 builds an invoice based on record 250). This page is accessible via a web browser and works fine.

On a completely different page (i.e. test.php) I’m trying to access that file via cURL. However, when I make the call and var_dump the results, I get bool(false).

Here’s the function that makes the cURL call:

function file_get_contents_curl($url) {
$ch = curl_init();

curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);

$data = curl_exec($ch);
curl_close($ch);

return $data;
}

HOME is a constant that denotes the full url (e.g. http://www.example.com/).

$invoice_contents = file_get_contents_curl(HOME.'viewinvoice.php?id=242');
echo $invoice_contents;
var_dump( $invoice_contents );

I’ve tried changing the url to an external url (i.e. http://www.google.com/) and the page loads just fine. I get google’s home page. But any page that’s in the same domain won’t load. Is there a reason that this would happen?

I am not the server admin, but I have root access to the server. I have not changed any settings recently, but the server admin may have upgraded the version of apache or php?

In any case, is there a setting I can modify to make this work again?

P.S. I just tried making this exact call from an external server (different domain) and it works just fine.

After your curl execution, put something like this :

echo curl_getinfo($ch) . '<br/>';
echo curl_errno($ch) . '<br/>';
echo curl_error($ch) . '<br/>';

You’ll see what failed during your curl execution.
