No, it doesn't. Variables inside a double quoted string are parsed. It's
perfectly valid code. The example you gave would also work, but it's
totally unnecessary.
Just try this and you'll learn something fun:
<?php
$cat = 'dog';
echo "I have an animal in my hand and the animal is a $cat. <br />";
echo 'I have an animal in my hand and the animal is a $cat. <br />';
?>
