Reading SCRIPT_FILENAME thru cron

[BG Mahesh]

hi

I am using PHP 5.0.4 on OpenSuse 10.x. I have the following piece of
code,

$sp1 = $_SERVER["SCRIPT_FILENAME"];

$sp1 is set correctly when I execute file.php thru the browser. But
when I run that script thru cron [as root] $sp1 is always null.

But on Redhat we see that $sp1 has value [when file.php is executed
thru cron].

We don't see any error messages on OpenSuse. What could we be doing
wrong? Any pointers are appreciated

From PHP manual:

$_SERVER is an array containing information such as headers, paths, and
script locations. The entries in this array are created by the webserver.
There is no guarantee that every webserver will provide any of these;
servers may omit some, or provide others not listed here. That said, a
large number of these variables are accounted for in the » CGI 1.1
specification, so you should be able to expect those.

The "webserver" thing is a typo, but it's true that available variables
differ depending on where you execute the script. I suggest you try this
code:

<?

print_r($_SERVER);

?>
It'll tell you what variables you can use.

When I run this script from the command line or the web it does show
SCRIPT_FILENAME [with the correct value]. But when the script runs from
cron it is NULL. Is this normal behavior?

Is the cron job calling the page through the web server? Or is it just
executing the script?

$_SERVER is filled in by the web server - and it won't exist if you
don't access the page though the server (http://...).

Not necessarily. I do get quite a large $_SERVER variable when running PHP
from command line. But as manual warns available values may vary.

hi

I think I found the problem. On the machine where things work I have
PHP-CLI and the other one that was giving me grief had PHP-CGI.

Where does one find rpms for PHP-5.0.4-CLI [OpenSuse]?
