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         


        

Answer 1

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.
