I want to create a simple php function to return an array of variable in wordpress template.

php function in function.php:

```
function testme (){
     $color = 'imaginary'; // or real  
     $y = 'yellow';
     $s = 'silver' ;

     if ($color != 'imaginary') {
            $y = 'golden';
            $s = 'silver' ;
     } else {
            $y = 'yellow';
            $s = 'white' ;
     }

     $wall = array();
     $wall = array ($y ,$s);
     return $wall;
}

```

Called this function in my template like this:

```
<?php 

testme();

?>

<h1>TOP STRIP COLOR IS <?php echo $wall['0'] ?></h1>
<h2>BOTTOM STRIP  COLOR IS <?php echo $wall['1'] ?></h2>

```

But I am not getting array of values in my `<h1>` and `<h2>` tags. Help me to point out my mistake.
