PHP Curl script works from browser, doesn't work as Cron Job

Question

I have a very simple PHP script that is supposed to make a POST request. The code is the following:

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($ch);
curl_close($ch);
mail('[email protected]','Script run with success','Script run with success',$headers);

When I execute it from the browser, it works fine. However, when I try to execute it as a cron job the Curl part won't work. The rest of the script works even as a cron job, as I receive the confirmation email at the end.

Here's the cron entry:

*/5 * * * * /usr/bin/php /home/username/scripts/test.php

Any clue regarding why Curl is not executing as a cron job?

Update: I tried to run the script via shell and the Curl part failed to run too. So:

Browser: curl works
Shell: curl doesn't work
Cron: curl doesn't work

Update 2: Adding -dsafe_mode=Off while running via shell make the script run fine. However adding the same flag to the cron entry didn't do anything. So I still need to figure out how to make it work from cron.

What happens when you simply run the script in the shell? It might be something as simple as you need to add the -f flag to the php binary - — rm-vanda

Where/how are you defining $url, $fields, and $headers? — Patrick Q

If you're relying on $_SERVER values in your cron script, it probably won't work. — Jeff Lambert

There are different php.ini files for webserver and CLI. Make sure the options relevant to your script are the same in both. — Barmar

$url, $fields and $headers are not the problem because when I test via the browser it works fine. I am not relying on any $_SERVER values either. — Daniel Scocco

It turned out to be an authentication problem. I solved it by adding the following two lines to the CURL configuration:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

Hope it helps someone.
