[on-asterisk] How to pass ${EXTEN} from dialplan to php file which accept variable $did_numb ???
Bruce N
Hi Everyone,
Trying to pass ${EXTEN} to a php file for processing. Not sure how to. The php file takes $did_numb as defined:
<?php$did_numb = $_GET['did_numb'];?>
I know that http://serverIP/file.php?did_numb=416-444-5555 works fine but when calling php file by system() from dialplan how can this be done?
exten => s,n,system(php file.php?did_numb=${EXTEN}) |||| This method doesn't work as "php file.php?did_numb=416-444-555" simply doesn't work from the CentOS prompt.
What is the proper syntax here?
I also want whatever that file.php returns to be saved in $var for later usage in dial-plan afterwards.
Thanks.

There are two ways to do this. If you insist on using a system() call you could pass the variable as an aguement. I don't recall how to use the system() function to pass an argument so I'll guess here:
exten => s,n,system(php file.php "${EXTEN}")
Then in PHP use:
#!/usr/bin/php
<?php
$did_numb = $_GLOBALS['argv'][1]
?>

Okay so what you really want is to use AGI. Get an AGI library for PHP. I recall using one called phpagi.php (http://sourceforge.net/projects/phpagi/)
You will want to use the get_variable() and set_variable() functions.
Again from memory:
exten => s,n,agi(file.php)
Then the PHP code
#!/usr/bin/php
<?php
// Use the phpagi library
require "phpagi.php';
// It's an object so let's instantiate it
$agi = new AGI();
// Get a variable from dial plan
$agi->get_variable($EXTEN);
// do something, like assign a value to $var
$var = "something";
// Set a dial plan variable
$agi->set_variable("var", $var);
exit(0);
?>

Thanks for that John. PHPAGI seems to be the right choice.
However when doing a NoOp I am getting channel info like ip and sip info for the variable. It seems to me that the variable is not passed the right way back to the dial-plan.
NoOp reults:
NoOp("SIP/64.64.65.65-00000d31", "") in new stack
Maybe the problem:
$agi->set_variable("var", $var);

Just so I'm clear, your doing something like:
exten => s,n,NoOP(${var})
And getting the results you mention? that doesn't show a channel name, but rather that ${var} contains "".
You probably want quite on the php, that could screw up the set_variable stuff.
#!/usr/bin/php -q
Of use the -q argument when invoking php.
P.S. There is a typo in my code below. The get_variable command should be:
$agi->get_variable("EXTEN");

Thanks for the great input again. It was the phpagi path that I had wrong in the .agi file. Once that was set properly everything works fine. Now, I need to find out a way to check status of a registered peer. Wondering if there is a request I can send for that in the phpagi?!
Thanks,
Bruce

I think you need to use the Manager API for that. Two ways:
You could use PHP's system() call to run "asterisk -r ...." and capture and parse the output.
Or you could get a asterisk manager library for PHP and do it as a function.
Which you choose depends on how often Asterisk will call the AGI script.

Going to resort to asterisk -rx as this is a simple call and want to temporarily solve the issue rather quickly but I need to find out what the escape charecter is for this line as it doesn't work:
$sip_peer = 2342342342
$peer_count = system('asterisk -rx "sip show peer $sip_peer" | grep -c "X-Lite"', $retval);
Above is supposed to return 1 if $sip_peer is registered (by utilizing grep -count) with X-Lite as word found and 0 if it is not registered but it always returns 0, I think because the " " are confusing php.
I searched and since no one probably uses asterisk -rx this way, there are no results on google. In addition, php people never use asterisk -rx either....so their solutions never include the use of " " inside ' '
What could be the escape charecter for I guess "sip show peer $sip_peer" and "X-Lite" part so it returns the proper value back.
Thanks,
Bruce

Thanks for the input. I tried that but it didn't work. Seems to be a bit more complex. However this works:
$peer_count = system("sudo /usr/sbin/asterisk -rx " . escapeshellarg("sip show peer $sip_peer\"\"") . " | grep -c X-Lite");
Thanks for all the help everyone.

Bruce,
Try this instead:
$peer_count = system("asterisk -rx \"sip show peer $sip_peer\" | grep -c \"X-Lite\"", $retval);
In php, when you use single quotes, the string will be interpreted as is, statically. Only when you use double quotes you'll have the variables getting translated.
