Answer 1

The way your code is written, if my name is Jay and I am 31 years old, the array will look like this...

{
'Jay' => 'Jay',
'31' => 31
}

The keys should be constant strings, and not (in this case) variables, as indicated by the $ sign.

Try this instead.

$result = array(
    'name'=>$name,
    'age'=>$age
);

This will yield

{
'name' => 'Jay',
'age' => 31
}

Important you must also change the way you are echo'ing your array values

//echo $result[$name];
echo $result['name'];

Answer 2

When passing it, you should not have the $ in the array key. Instead they should be quoted strings:

// Incorrect:
$result = array($name=>$name,$age=>$age);

// Should be:
$result = array('name'=>$name,'age'=>$age);
