Hi,

I am using Asterisk certified/16.8-cert3

and in AGI I am setting the static value and need to retrieve or get the same value

$fastagi-\>set\_variable(“plan\_id”, 123);  
$plan\_id = $fastagi-\>get\_variable(‘plan\_id’);  
$fastagi-\>verbose(“MYRESULT-\>”.$plan\_id);

Below is my full debug log line where it shows that I am getting the value “123” but not able to use that in the same AGI, just wanted to know the functionality for get\_variable

[Jan 18 07:10:43] DEBUG[853153][C-00000002]: pbx\_variables.c:375 ast\_str\_retrieve\_variable: Result of ‘plan\_id’ is ‘123’

Why are you using a certified version, rather than the latest, when you aren’t getting paid support from Sangoma?

Which AGI class library are you using?

You don’t appear to have enabled AGI debugging.

Hi @david551

I will upgrade to Asterisk 18.1  
and currently, we are using PHP-AGI 2.2

Below is the AGI Debug enabled logs where I am getting the information that get\_variable has the value “123” but unable to use that in my agi file

\<PJSIP/1002202-0000000c\>AGI Tx \>\> 200 result=1  
\<PJSIP/1002202-0000000c\>AGI Rx \<\< GET VARIABLE plan\_id  
\<PJSIP/1002202-0000000c\>AGI Tx \>\> 200 result=1 (123)

That suggests the problem lies with the library, rather than Asterisk.

declare the variable on the php enviroment

$myvar=123;

looks this method set\_variable() doesnt not create the variable on php side.

Your console log snippet shows you retrieved the channel variable, but not what happened when you execute ‘verbose()’. It probably looks like:

```auto
<SIP/poly-77a1-00000007>AGI Rx << VERBOSE "MYRESULT->Array" 1
 example.php: MYRESULT->Array
<SIP/poly-77a1-00000007>AGI Tx >> 200 result=1

```

meaning ‘$plan\_id’ is an array, not a scalar.

The ‘get\_variable()’ method, returns an array. The array consists of 3 members: code, data, and result. You can access the members like:

```auto
        $agi->verbose('code->'.$plan_id['code']);
        $agi->verbose('data->'.$plan_id['data']);
        $agi->verbose('result->'.$plan_id['result']);

```

Which will result in a console log like:

```auto
<SIP/poly-77a1-00000008>AGI Rx << VERBOSE "code->200" 1
 example.php: code->200
<SIP/poly-77a1-00000008>AGI Tx >> 200 result=1
<SIP/poly-77a1-00000008>AGI Rx << VERBOSE "data->123" 1
 example.php: data->123
<SIP/poly-77a1-00000008>AGI Tx >> 200 result=1
<SIP/poly-77a1-00000008>AGI Rx << VERBOSE "result->1" 1
 example.php: result->1

```

If return an arrary then is just use the key and value holding the data

Hi @sedwards, Thanks but it is not working in my case as I am using fastagi on Ast 18.1.1 with PHP-AGI 2.2

```auto
$fastagi->set_variable("plan_id", "123654");
$plan_id = $fastagi->get_variable("plan_id");

 $fastagi->verbose(print_r($plan_id, TRUE));
 $fastagi->verbose(print_r(${plan_id}, TRUE));

$fastagi->verbose('code->'.$plan_id['code']);
$fastagi->verbose('data->'.$plan_id['data']);
$fastagi->verbose('result->'.$plan_id['result']);

Which version of AGI you are using?

At this stage of the game, I don’t think fastagi is your issue. Try just ‘plain agi’ to confirm.

The AGI protocol is a line oriented request/response kind of animal – you issue 1 request, you read 1 response, lather, rinse, repeat.

I suspect using print\_r() is your issue. This is going to output a mulit-line description of $plan\_id, thus, breaking the AGI protocol. Try it without the 2 verbose(print\_r()) statements.

Which version of _phpagi_ am I using? 2.20.
