Mixing PHP variable with quotes on a string literal

Question

I'm trying to add " " on a php variable,

What i have:

$id = 123;
echo "{$id}"; //123 

How can i return "123" instead of just 123?

echo ""{$id}""; //adding extra columns is not working

Answer 1

You escape the double quotes you want in the string with the \ backslash, like this:

$id = 123;
echo "\"{$id}\"";
