Embedding Variables in a String
Lab: PHP String Building and Processing Basics
Video Runtime: 15:16
PHP provides the means for us to build dynamic strings, i.e. strings that have varying strings within them. One method is to embed a variable directly into the string.
When PHP comes to a single quote, it handles the string within the quotes as a string literal. There is no processing that happens. Rather, it treats it as a hard-coded string. Therefore, if you wrote echo 'My name is {$first_name}.', the entire string would be rendered out to the browser just as you wrote it. The variable would not be processed.
