Convert array index to custom value?

Question

I have an array $indexedarray

printr($indexedarray) gives something like this

array (size=3)
  0 => string 'Homes' (length=5)
  1 => string 'Apartments' (length=10)
  2 => string 'Villas' (length=6)

I want to change this arrays index also same as value, like

array (size=3)
  'Homes' => string 'Homes' (length=5)
  'Apartments' => string 'Apartments' (length=10)
  'Villas' => string 'Villas' (length=6)

is it posssible??

At Stack Overflow you are expected to try to write the code yourself. After doing more research if you have a problem you can post what you've tried with a clear explanation of what isn't working and providing a Minimal, Complete, and Verifiable example. I suggest reading How to Ask a good question and the perfect question. Also, be sure to take the tour and read this. — John Conde

You can use array_combine:

$indexedarray= ['Homes', 'Apartments', 'Villas'];
print_r(array_combine($indexedarray, $indexedarray));

Gives:

Array
(
    [Homes] => Homes
    [Apartments] => Apartments
    [Villas] => Villas
)

But be aware that your duplicate values will be dropped. Keys will be unique!

What if those values are dynamic? How will know know what values to put into $arr?

At the hour of need, it can be done, but not before!

You mean at the time of building this array?

Yes, at the time of building that array

Yes it can be done when initializing - $indexedarray[$value] = $value instead of just $indexedarray[] = $value. But not sure how OP is filling this array!

Try This :

$myArray = [
   0 => 'Homes',
   1 => 'Apartments',
   2 => 'Villas' ];


$newArray = [];

foreach($myArray as $key => $value){
  $newArray[$value] = $value;
}

var_dump($newArray);

It will remove duplicates as arrays can only have unique keys
