Hi !

 

            I'm trying to use ecasound with PHP (PHP 4.1.2 - Debian Stable).

 

            It works like a charm when I launch it from an SSH session as
root but when I tried to launch the same command line with this code in PHP
:

 

  error_reporting(E_ALL);

 

  $handle = popen('ecasound -i:/var/www/davina.mp3 -o:/var/www/davina.ogg
2>&1', 'r');

  echo "'$handle'; " . gettype($handle) . "\n";

  $read = fread($handle, 2096);

  echo nl2br($read);

  pclose($handle);

 

I get :

 

'Resource id #1'; resource
