Do not read the file, but include it and use output bufferig to capture the outcome.

ob_start();
include 'main.php';
$content = ob_get_clean();

// process/modify/echo $content ...

Use a function to generate a new variable scope.

function render($script, array $vars = array())
{
    extract($vars);

    ob_start();
    include $script;

$test = 'one';
echo render('foo.php', array('test' => 'two'));
echo $test; // is still 'one' ... render() has its own scope
