just built this function, how can I make it better? (multidimensional)

[raccer]

/**
 * preforms a str_replace on every key in passed array (1-Dimensional only)
 *
 * @param $array the array to be processed
 * @param $pattern the string to be replaced/removed
 * @param $replace(optional) leave empty to remove $pattern,
 * 		   or pass a string to replace with.
 *
 * @return the new array
 */
function keyReplace($array, $pattern, $replace = "") {
	$newArray = array();
	foreach ($array as $key => $value) {
		$newKey = str_replace($pattern, $replace, $key);
		$newArray[$newKey] = $value;
	}
	return $newArray;
}

 

I'm a programming noob, just finishing my first php class.... so go easy on me

 

Whats the simplest way to make this function multidimensional array capable? I.E. every key on n^th level will be processed.

 

Thanks for the input!

Make it more re-usable:

 

function keyReplace($key, $pattern, $replace) {
  return str_replace($pattern, $replace, $key);
}

function replaceKeys($array, $pattern, $replace) {
  foreach (array_keys($array) as $key) {
    keyReplace($key, $pattern, $replace);
  }
}
