What are the best practices for echoing multiple strings in PHP to avoid errors?

When echoing multiple strings in PHP, it is important to concatenate them using the dot (.) operator to avoid errors. This ensures that the strings are properly combined before being outputted. Additionally, using double quotes around the strings allows for variables to be interpolated within the echoed output. 

// Concatenate multiple strings with the dot (.) operator
echo "Hello, " . "world!";

// Output with variables interpolated
$name = "John";
echo "Hello, $name!";
