Using associative array values from within the same array

Question

I'm trying to access an associative array's key and value from within the same array. If I have 3 pairs in my array. Can I use the value of let's say the values of something and other within the third one another?

$gar = array("something" => "something value", 
             "other" => "other value", 
             "another" => something . other 
       );

The idea is that another's value will be "something valueother value".

Is this possible? Is there a way to accomplish the same thing?

Answer 1

It should be fine if you use it on multiple lines like this:

$gar = array();
$gar["something"] = "something value";
$gar["other"] = "other value";
$gar["another"] = $gar["something"].$gar["other"];

You could even put the above sequence in a loop then.

Answer 2

how about just something like this

$gar = array("something" => "something value", 
         "other" => "other value"
   );

$gar["another"] = $gar["something"] . $gar["other"];

Answer 3

my question speaks about the analogous problem too. Hope that helps! :)
