How can i change the key of the array with the value of the same array in PHP?

Question

This is the result of my array:

array(3) {
  [968]=>
  string(12) "TRALALAA0"
  [918]=>
  string(23) "TRALALAA1"
  [912]=>
  string(66) "TRALALAA2"
}

I want that output would be:

 array(3) {
      ['TRALALAA0']=>
      string(12) "968"
      ['TRALALAA1']=>
      string(23) "918"
      ['TRALALAA0']=>
      string(66) "912"
    }

Is there a function to do that stuff in PHP ?

Using the array_flip() function

You can use array_flip for this.

$valsAsKeys = array_flip($array);

You are looking for array_flip()

$arr = array_flip($arr);
