Pull One Key

[lilman]

I have an associative array, and I want to pull each key of the array by using a loop, but I am not sure how to pull just the key in the array. Could someone inform me how I can do this, thank you.

[code]
<?php
  $array = array('foo' => 'bar','bill' => 'bob');
  $keys = array_keys($array);
  foreach ($keys as $key) {
    echo $key."\n";
  }
?>
[/code]
