Passing content of web page as string argument in shell_exec()

Question

If I pass string content then it works fine and on submit it shows me result. But when I pass the content of webpage received using escapeshellarg(strip_tags($text));. It shows nothing on the screen.

<?php
//sent has value "http://www.paulgraham.com/herd.html"
$url=$_POST['sent'];
$text = file_get_contents($url);
$temp=escapeshellarg(strip_tags($text));
//$temp="one two two"; If I pass $temp with string content it gives result
echo $temp;  //Echo $temp shows content of webpage 
$output=shell_exec("/home/technoworld/Videos/LinSocket/Modular/x '$temp'");
echo $output;
?>
