Implode not working

[r_sole]

Hi.

I have a variable variable called

${'stringstack_'.$categoryno} = array();

Im new to the variable variable thing..

And Im trying to implode that array but for some reason it wont work (I think because of the use of a variable variable)

foreach ($categorynos as $categoryno)
  {
   implode("','",${'stringstack_'.$categoryno});
}

I can directly echo variables from the array. and use count on the array..

  echo ${'stringstack_'.$categoryno}[0];
  echo count(${'stringstack_'.$categoryno});

that works fine for some reason

But what do you do with the results of the [man]implode[/man]? Nothing, judging by that code.

Incidentally, I can't remember the last time I had to deal with variable variables myself: better ways of managing data exist (e.g., associative arrays). Oh, wait; I think it was in an Obfuscated PHP gag.

works for me.

$myarray = [1,2,3,4,5];

$mine = 'my';
$imploded = implode( ',',${$mine.'array'} );

var_dump( $imploded );
/* prints:

string(9) "1,2,3,4,5"

*/

What do you mean by "it wont work"[sic]? You need to describe what is going wrong.
