php - curl - proxy ? help plz

[AjiNIMC]

Hi all,
I am trying to do some proxy stuff , I am able to retrieve the page but not able to catch the return , what I am doing is

passthru("curl --proxy 195.115.142.120:80 xyz.com");

or

exec("curl --proxy 195.115.142.120:80 xyz.com");

It throws the results (displays the xyz.com) to my page but I want to catch that in a variable like

$variable=passthru("curl --proxy 195.115.142.120:80 xyz.com");
or
$variable=(some php fucntion)("curl --proxy 195.115.142.120:80 xyz.com");

echo $variable ,

should give me the page.

Regards

<?php

ob_start();
passthru("curl -s www.google.com");
$var = ob_get_contents();
ob_end_clean();

echo "-- START --\n\n$var\n\n-- END --\n";
?>

The variable $var holds the page data.
