Please help me, why class Sphinx gives me empty $result when I run it from AGI, but gives me not empty $result, when I run it from bash. Also class Yandex gives not empty correct $result with both situations. Initial voice_rec.php
#!/usr/bin/php5
<?php
$start = microtime(true);
spl_autoload_register(function ($class) {
include 'Classes/' . $class . '.php';
});
$stdin = fopen('php://stdin', 'r');
$stdout = fopen('php://stdout', 'w');
$stdlog = fopen('my_agi.log', 'w');
$filename = $argv[1];
$table = $argv[2];
$number = $argv[3];
$VoiceClass = new Sphinx();
$result = $VoiceClass->voice2Text($filename);
echo "VERBOSE $result
";
return $result;

exec($command, $ans);
$result = implode("",$ans);
return $result;

Yandex.php (which is working well both in AGI and Bash)
<?php

$res_xml = implode($xml);
if (preg_match('!<variant .*?>(.*)</variant>!si', $res_xml, $arr)) $voice_text = $arr[1];

$result = strtolower($res_xml);
