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

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];
