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