Is there a difference between using single quotes and double quotes in PHP strings?

In PHP, there is a difference between using single quotes and double quotes in strings. Single quotes are used to define literal strings where variables are not parsed, while double quotes allow for variable parsing within the string. If you want to include variables within a string, you should use double quotes. 

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