How to replace array key by its value

I have the following array:

array('Elnett', 'INOA INOA', 'Playball P', 'Preferred Color Specialist', 
      'Série Expert', 'Série Nature', 'Tech开发者_C百科ni art')

I would like to have keys and values like:

array('Elnett' => 'Elnett', 
      'INOA INOA' => 'INOA INOA', 
      'Playball P' => 'Playball', 
      'Preferred Color Specialis' => 'Preferred Color Specialist', 
      'Série Expert' => 'Série Expert', 
      'Série Nature' => 'Série Nature', 
      'Techni art' => 'Techni art')

How can I accomplish this?

There's array_combine to create a key/value array out of two arrays. Should be possible to use the same array for keys and values:

$names = array_combine($names, $names);

This one-line answer may be useful to someone.

$trans = array_flip($array);

http://us1.php.net/array_flip

array_flip returns the value=>key format of given key=>value array. as the question changed, this does not exactly answer the OP's question anymore.

Could do something like this. Not sure if there is a cleaner way to do it.

foreach($names as $key => $name){
    $names[$name] = $name;
    unset($names[$key]);
}

foreach($array as $key=>$value){
    $out[$value] = $value;
}

print_r($out);
