What are some best practices for concatenating strings in PHP to achieve the desired outcome?

When concatenating strings in PHP, it is best practice to use the dot (.) operator to combine multiple strings. This ensures that the strings are concatenated in the desired order and format. Additionally, using double quotes around the strings allows for variable interpolation, making the code more readable and maintainable. 

// Example of concatenating strings in PHP
$string1 = "Hello";
$string2 = "World";
$concatenatedString = $string1 . " " . $string2;
echo $concatenatedString; // Output: Hello World
