fwrite not working when called from Cron

[kayb91]

The subject pretty much sums it up. I've written a script to create a file and chmod to 0777. Then the script writes data to the new file. When I call it from my browser it works. When I call it from Cron, it creates the file and chmod's the file successfully. However it will not write any data to the file.

Is there something special that I should be doing? Here is the code I am using to write to the file:

$filename = $userid.'.txt';
$content = "<center>Hello World.\n";

if (is_writable($filename)) {

if (!$handle = fopen($filename, 'a')) {
     print "Cannot open file ($filename)";
     exit;
}

if (!fwrite($handle, $content)) {
    print "Cannot write to file ($filename)";
    exit;
}

print "Success, wrote ($content) to file ($filename)";

fclose($handle);

} else {
print "The file $filename is not writable";
}

As previously stated, this code works when called from my browser, but fails when called from Cron.

Any ideas why? 😕

Could it be a path problem?

The writeable file may not be in the current dir when run from cron.

I tried that too. Here is the path that I used to create the file:

$ftp_file="/public_html/user/reports/$userid.txt";

I changed the code in the above code to reflect this same path but still no luck.

That also worked from the browser but not from cron. 😕

Does the file already exist?

It may be a problem with cron being run as a different user.
It should work if the files exists and is chmod to 777.
If not, it probably won't work.

Thank You. It was a path problem. The path that finally worked was /home/loginid/public_html/user/reports/$userid.txt

Thanks for brainstorming with me 🙂

No problem, thats what forums are for.
