Trying to create an array from two values of an array

Question

So I'm iterating over this $elements array. I am trying to get the key and value from each individual item of the $elements array, which is also an array (which I will call $element).

Here's my code:

  $options = array();  
  foreach ($elements as $element) {
    if ($element['#active']) {
      continue;
    }


    $options[$element]['#query'] = $element['#indexed_value'];



  }

This doesn't work. How would I get the value of $element['#query'] and $element['indexed_value'] as a key => value pair?

Can you provide a sample of the array that you're iterating through, and a sample of the expected results? — Armin

At first glance, you are using $element as an array and as an array key. It does not matter what your script is doing; it will not work. — Sverri M. Olsen

try this

 $options[$element['#query']] = $element['#indexed_value'];

I execute following code

 $options["junaid"] = "hassan";
 echo print_r($options, true);

Got following result

 Array
 (
     [junaid] => hassan
 )

It gives me, "array()" when I print_r($options, true);

Hmm If I understand the problem:

$elements = array(array('a' => 1, 'b' => 2, 'c' =>3), array('d' =>4, 'e' =>5,'f' =>6) );
$options = array();
$temp = array();
$temp2 = array();

//value is each array in $elements
foreach ($elements as $element) {       
    $temp = array_merge($temp, array_keys($element));   
    $temp2 = array_merge($temp2, array_values($element));   
}
$options = array_combine($temp, $temp2);
var_dump($options);

and it produces this output:

array(6) { ["a"]=> int(1) ["b"]=> int(2) ["c"]=> int(3) ["d"]=> int(4) ["e"]=> int(5) ["f"]=> int(6) }
