What is the significance of using single quotes in PHP variables and escape sequences?

When using single quotes in PHP variables, escape sequences are not interpreted within the string. This means that special characters like \n or \t will be treated as literal characters rather than their special meaning. To include escape sequences in a string with single quotes, you can use double quotes instead. 

// Using double quotes to include escape sequences in a string
$name = "John\nDoe";
echo $name; // Output: John
            //        Doe
