Often we need to build strings incrementally. A good example is with building an output HTML string pattern or even a message. You build part of it, do some processing, and then keep appending to the same string and assigning it back to the variable.
PHP gives you a shortcode operator for this process that turns:
$message = $message . 'Welcome ' . $first_name;
$message .= 'Welcome ' . $first_name;.
Both of these lines of code are processed the same way by the PHP interpreter. First, the strings are concatenated. Then the assignment is made to the variable
There’s a time to code and …. yup, that sums it up.
