exec not found

[androidealp]

I got an error:
http://www.samba33.com/teste/teste.php

My python version is 2.6.6.
I update new version youtube-dl "youtube-dl -U"

I try this script:

<?php 
    $url = "http://www.youtube.com/watch?v=coq9klG41R8";
    $template = 'youtube-dl "'.$url.'" -f 18 -o "/var/www/vhosts/samba33.com/httpdocs/teste/%(id)s.%(ext)s"';
    exec($template);

    $string = ('youtube-dl ' . escapeshellarg($url) . ' -f 18 -o ' .
          escapeshellarg($template));

    $descriptorspec = array(
   0 => array("pipe", "r"),  // stdin
   1 => array("pipe", "w"),  // stdout
   2 => array("pipe", "w"),  // stderr
);
    $process = proc_open($string, $descriptorspec, $pipes);

    $stdout = stream_get_contents($pipes[1]);
fclose($pipes[1]);
$stderr = stream_get_contents($pipes[2]);
fclose($pipes[2]);
$ret = proc_close($process);
echo json_encode(array('status' => $ret, 'errors' => $stderr,
                       'url_orginal'=>$url, 'output' => $stdout,
                       'command' => $string));
?>

Could you help me to identify the error?

It looks like youtube-dl is not in the PATH of your web user's account. Type which youtube-dl to find out where the binary is installed, and env to see the environment variables.

You can either fix the path (by modifying the PATH environment variable for the webserver user), or use the complete path (i.e.

$string = 'python /PATH/GOES/HERE/youtube-dl ' . escapeshellarg($url) . ' - f 18 -o ' . escapeshellarg(template);

or download youtube-dl into the local directory, and then call the local version

$string = 'python ./youtube-dl ' . escapeshellarg($url) . ' - f 18 -o ' . escapeshellarg(template);

By the way, you should either use exec or proc_open - otherwise, you'd call youtube-dl twice.

I'm closing this issue now since any of the above solutions should fix it. You are however more than welcome to comment, both if it works and if it doesn't. We'll open the issue then if necessary.
