PHP double quote and single quote

$some="Oh god";

echo "My answer is $some ";

//result is: My answer is Oh god

In the above, using double quotes, the variable $someis evaluated within the quotes and the result isn't what is expected: the variable is evaluated to Oh god. Variables, but not functions or constants, are evaluated even when enclosed in double quotes.

echo 'My answer is $some';

//result is: My answer is $some.

When single quotes are used, as above, the variable isn't evaluated and is printed on the screen literally as $some.
