Method inside output buffer not working

Question

Assume having just a trivial snippet:

public function myMethod($file)
{
    require $file;
}

public function capture($file, array $args)
{
    extract($args, EXTR_SKIP);

    ob_start();

    $this->myMethod($file); //not working
    require $file; //works

    return ob_get_clean();
}

Could anyone explain why the snippet above works in case of using require only and not when using the method?

Answer 1

You need to make available the parameters to myMethod:

public function myMethod($file, array $args)
{
    extract($args, EXTR_SKIP);

    require $file;
}

public function capture($file, array $args)
{
    ob_start();

    $this->myMethod($file, $args);

    return ob_get_clean();
}

See about the scope of a variable.
