我如何只从var转储数组中获取值？

Question

Is it possible to escape array(1) { [0]=> string(12)} from var_dump($variable) because I want to show only values from var_dump and except array string?

Testing Code

 <?php
 $array = array(
 "foo" => "bar",
 "bar" => "foo",
 100   => -100,
-100  => 100,
 );
 var_dump($array);
 ?>

now results will be like this

array(4) {
["foo"]=>
string(3) "bar"
["bar"]=>
string(3) "foo"
[100]=>
int(-100)
[-100]=>
int(100)
}

But I want to get only bar and foo values except string(3) and array(4)?

Try

<?php
  $array = array(
    "foo" => "bar",
    "bar" => "foo",
    100   => -100,
    -100  => 100,
  );

  echo '<pre>';
  print_r($array);
  echo '</pre>';
?>
