[Asterisk-Users] Re: AGI GET Variable Problem

[Kenige Ho]

Dear All,

 

Never Mind, I have solved the problem.  It seems that you should clear the buffer for any 'waiting' response or else you will be getting an empty '200 result=1' response.  So be sure to read, before you write in php agi script to ensure that you will get a proper response.

Dear All,

 

I am trying to get a variable via AGI "GET VARIABLE XXXX", but using AGI DEBUG I actually do see the variable get return but somehow my retrieving the variable via php.  I don't get the value of the variable.  Below is my code and my results.  Please help.  thank you.

 

Coding:

#!/usr/bin/php -q
<?php
ob_implicit_flush(true);
set_time_limit(6);
$in = fopen("php://stdin","r");
$stdlog = fopen("/var/log/asterisk/my_agi.log", "w");

// toggle debugging output (more verbose)
$debug = false;

// Do function definitions before we start the main loop
function read() {
        global $in, $debug;
        $input = str_replace("\n", "", fgets($in, 4096));
        if ($debug) fputs($stdlog, "read: $input\n");
        return $input;
}

function errlog($line) {
        global $err;
        echo "VERBOSE \"$line\"\n";
}

function write($line) {
        global $debug;
        if ($debug) fputs($stdlog, "write: $line\n");
        echo $line."\n";
}

// parse agi headers into array
while ($env=read()) {
        $s = split(": ",$env);
        // $agivar[str_replace("agi_","",$s[0])] = trim($s[1]);
        // errlog($s[0].",".$s[1]);
        $agivar[$s[0]] = trim($s[1]);
        if(($endid.phpv=="") || ($env=="\n")) {
        break;
        }
}

// main program
echo "VERBOSE \"fone-check\"\n";
$tmp = "GET VARIABLE xxxxx";
write($tmp);
errlog("Temp Var is " . $tmp);
$result = read();
errlog("Before Strip Result is " . $result);
$result = trim(ereg_replace("200 result=1","",$result));
$result = trim(ereg_replace("\(","",$result));
$result = trim(ereg_replace("\)","",$result));
errlog("After Strip Result is " . $result);

// clean up file handlers etc.
fclose($in);
fclose($stdlog);

exit;
?>

Results:
