i am running one linux command with shell_exec() in my php script. 

$output = shell_exec('/usr/bin/linux-command ');

After execution of the command i am getting the value into a variable. That's okay.
But, here my linux command will give the output continuously in terminal.
It will come like this.. 

$linux-command  
123    456    789  
789    456    123  
123    456    789 .. //and so on..(by pressing 'Ctrl+c' only we can stop this.

For every 5 seconds it will display one line. how to retrieve the line for every 5 sec.
My Page is in loading ........ Because, it is waiting for the $output.
Is there any way to solve my problem ??
Any idea is appreciated. Thank you in advance

Try the passthru function. The output is displayed directly. You can test it with this small script:

<?php
passthru('tail -f /var/log/apache2/access.log');
?>

  • sorry I thought the you were talking about a cli script not a web script. – lexmihaylov May 30 '13 at 13:12
  • Hmm. can you use shell_exec($command.' > '.$filename.' 2>'.$filename.' &'); and after that just periodicaly get with an ajax method the contents from $filename, parse it and do something with it ? – lexmihaylov May 30 '13 at 13:16
