In the php script below I use 3 variables:
1. &day
2. $hour
3. $minute.


Filename:/opt/lampp/htdocs/uptime/uptime.php

$data = shell_exec('uptime');
$uptime = explode(' up ', $data);
$uptime = explode(',', $uptime[1]);
$uptime = $uptime[0].' ' .$uptime[1];


$days = explode(' ', $uptime);
$hours = explode(':', $days[3]);

$day = $days[0];
$hour = $hours[0];
$minute = $hours[1];

?>

Question: How to I pass those 3 variables from the script, to 3 variables in
Linux (Debian).

Something like:
asterisk:~# day=${CURL(http://localhost/uptime/uptime.php)} (?????)
asterisk:~# hour=...........
asterisk:~# minute=.........

You would need to use

export day=`php /path/to/yout/file/uptime.php`

if you use it this way, you need to make the script to take arguments, so that
you can get the day, hour and minute alone. Don't forget to echo about the value.

Otherwise you can use a shell script with awk that can read out the values and
then set each variable, but then you could skip using php, as you get the
uptime from uptime command directly.

Can you please be a little bit more specific. It's not quit clear to me.
Why (and how) must the script take arguments?
The values of the 3 variables are already known to the script.
I only need to pass them to the operating system.

You right, this is also a possibility.

But what's the operating system going to do with them?

The operating system doesn't take parameters. Rather, you run a program
(even if it is the shell) which does something with parameters.

As you can't export three shell variables at the same time, you require to set
them one at the time. If you still want to output all three at the same time
in the php script, then you need to use awk or another string manipulating
command and in which case it's less overhead to make a shell script that does
all itself.

The values are already "stored" in the OS in question, it do have track of
it's own lifespan, but of course not stored as a variable that is accessible
by the shell.

if the OP exports the value, they will only be in the shell he currently works
in, switching to another virtual console will just make that the variables in
question are empty as they never been set.
Of course it would be possible to set the values in ~/.bashrc, but then the
values will be different for each shell.

Not sure if the OP really thought about what he wants to do...

Yes jerry, you are right. That's exactly what I want.
Sorry for my confusion.

I want to pass the values of the three variables in the php script to my PBX
dial plan (Asterisk):

exten => 3014,1,Playback(wait-moment)
exten => 3014,n,Set(days=...) <----Here I need the value of $days from the
php script.
exten => 3014,n,Set(hours=..) <----Here I need the value of $hour from the
php script.
exten => 3014,n,Set(minutes=..)<---Here I need the value of $minutes from
the php script.
exten => 3014,n,System(echo "the server uptime is ${days} days and ${hours}
hours and ${minutes} minutes" | /usr/bin/text2wave -scale 1.5 -F
8000 -o /tmp/uptime.wav)
exten => 3014,n,Playback(/tmp/uptime)
exten => 3014,n,System(rm /tmp/uptime.wav)
exten => 3014,n,Playback(goodbye)
exten => 3014,n,Hangup()
>


I use something similar to get my account balance from the web:

exten => 3000,1,Answer
exten => 3000,n,Playback(astcc-account-balance-is)
exten =>
3000,n,Set(status=${CURL(http://localhost/credit/credit_dialnow.php)})
<----HERE I GET MY ACCOUNT BALANCE.
exten => 3000,n,SayDigits(${status})
exten => 3000,n,Playback(vm-goodbye)
exten => 3000,n,Hangup()

Please Aho see my reply to Jerry.
With awk I can get my dial plan working.

But I want to learn how to do it with a php script.
