How does PHP handle variables within strings when using single quotes versus double quotes?

When using single quotes in PHP, variables within strings are not parsed and will be treated as literal text. To include variables within strings and have them evaluated, you should use double quotes instead. 

$name = "Alice";
echo 'Hello, $name'; // Output: Hello, $name
echo "Hello, $name"; // Output: Hello, Alice
