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?

Yes, you can store variables within arrays, though you'll need to remove the space between $result and the opening bracket.
Assigning values to an element in an array is similar to assigning values to scalar variables. Simply reference an individual element of an array using the array name and the index inside parentheses, then use the assignment operator (=) followed by a value.
To create an array in PHP, we use the array function array( ) . By default, an array of any variable starts with the 0 index. So whenever you want to call the first value of an array you start with 0 then the next is 1 ...and so on. There are different types of arrays in PHP.
The + operator in PHP when applied to arrays does the job of array UNION. $arr += array $arr1; effectively finds the union of $arr and $arr1 and assigns the result to $arr .
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.
