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"] . "";
$info = array('$id','Example');
echo $info[0];
Is this possible in any way?

What you need is (not recommended):
$info = array("$id",'Example'); // variable interpolation happens in ""
or just
$info = array($id,'Example'); // directly use the variable, no quotes needed
You've enclosed the variable inside single quotes and inside single quotes variable interpolation does not happen and '$id' is treated as a string of length three where the first character is a dollar.

Just don't put it in quotes:
$id = $result["id"];
$info = array($id, 'Example');
echo $info[0];
Alternatively, if you use double quotes rather than single quotes, then it will be interpolated (which also results in it being converted to a string):
$id = $result["id"];
$info = array("$id", 'Example');
echo $info[0];

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;
}
