What are the basic syntax rules in PHP?

PHP has a fairly simple and intuitive syntax that is easy to learn, even for beginners. Here are some basic syntax rules to keep in mind when writing PHP code:

  1. All PHP code must be enclosed in <?php ?> tags.
  2. PHP statements must end with a semicolon (;).
  3. PHP variables are preceded by the $ symbol.
  4. PHP comments can be added using // or /* */.
  5. PHP is not case-sensitive, so variables named $name, $Name, and $NAME are all considered the same.
  6. PHP strings can be enclosed in single quotes (”) or double quotes (“”).
  7. PHP functions are called using the function name followed by parentheses, like so: functionName().

By following these basic syntax rules, you can start writing PHP code that is easy to read, understand, and maintain.
