How can variables be properly accessed and utilized in PHP?

To properly access and utilize variables in PHP, you need to ensure that they are correctly declared and assigned values before using them in your code. Variables in PHP are preceded by a dollar sign ($) and can store different types of data such as strings, integers, arrays, and objects. To access a variable's value, simply reference its name with the dollar sign. Make sure to pay attention to variable scope as variables declared within a function are only accessible within that function unless declared as global. 

$name = "John";
$age = 25;

echo "My name is " . $name . " and I am " . $age . " years old.";
