How do I insert a variable into a PHP array?

Question

I have looked for some responses on the web, but none of them are very accurate.

I want to be able to do this:

$id = \"\" . $result [\"id\"] . \"\";
$i

Yes, you can store variables within arrays, though you'll need to remove the space between $result and the opening bracket.

$foo = $result["bar"]; // assuming value of 'bar'

$collection = array( $foo, "fizz" );

foreach ( $collection as $item ) {
  // bar, fizz
  echo $item;
}
