How to replace array key by its value

Question

I have the following array:

array('Elnett', 'INOA INOA', 'Playball P', 'Preferred Color Specialist', 
      'Série Expert', 'Série Nature', 'Techni 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?

Answer 1

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);

Answer 2

This one-line answer may be useful to someone.

$trans = array_flip($array);

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.
