Making PHP var_dump() values display one line per value

Question

When I echo var_dump($_variable), I get one long, wrapping line with all varable\'s and values like

[\"kt_login_user\"]=>  string(8) \"teacher1\" [\"kt_lo

For devs needing something that works in the view source and the CLI, especially useful when debugging unit tests.

echo vd([['foo'=>1, 'bar'=>2]]);

function vd($in) {
  ob_start(); 
  var_dump($in);
  return "\n" . preg_replace("/=>[\r\n\s]+/", "=> ", ob_get_clean());
}

Yields:

array(1) {
  [0] => array(2) {
    'foo' => int(1)
    'bar' => int(2)
  }
}
