Question

From the topic itself, how am i supposed to do that?… I’m getting the output from linux to Php using pipes.

e.g

echo "<textarea cols='100' rows='20' readonly='readonly' style='resize:none;'>";

       $dev = stream_get_contents($pipes[1]);

       echo $dev;

       echo "</textarea>";

       fclose($pipes[1]);

Here is my form.

<form method="post">
<input type="radio" name="cmd" value="./iodev scan">Scan<br />
<input type="radio" name="cmd" value="./monitor">Enable Monitoring<br />
<input type="submit" value="GO">
</form>

Now when i got the data i need it to retain in the textarea when loaded into a new tab or page or on page reload it will sit there and not disappear.

Thanks,

You can try something like amusing your textarea name is textPipes

if (!isset($_POST['textPipes']) || empty($_POST['textPipes'])) {
    $_POST['textPipes'] = stream_get_contents($pipes[1]);
    fclose($pipes[1]);
}

echo "<textarea cols='100' rows='20' readonly='readonly' style='resize:none;' name='textPipes' >";
echo $_POST['textPipes'];
echo "</textarea>";

* EDIT ! *

Based on your request you can also sore it in Memcache

$mem = new Memcache();
$mem->connect("localhost",11211);

#Identify current user
$currentUser = "demic0de";

#Create Unique Key
$key = $currentUser . sha1($pipes[1]);

if(!$mem->get($key))
{
    #set value and expire every 10 mins 
    $mem->set($key,stream_get_contents($pipes[1]) ,null,600);
    fclose($pipes[1]);
}


echo "<textarea cols='100' rows='20' readonly='readonly' style='resize:none;' name='textPipes' >";
echo $mem->get($key);
echo "</textarea>";
