What is PHP Syntax?
PHP syntax defines the rules and structures needed to create proper PHP code.
This section explains how to manage PHP tags and perform actions like declaring variables and writing functions while demonstrating the use of control structures and embedding PHP code into HTML.
PHP Tags
PHP code must be contained within these specific tags.
<?php // Your PHP code here ?>
- PHP files typically have a .php extension
- PHP considers any content located outside its tags as HTML code.
Echo and Print Statements
These are used to output text to the browser.
echo "Hello, World!"; print "Welcome to PHP!";
Echo operates with better speed while handling multiple parameters but print returns a value (1).
Example
<!DOCTYPE html>
<html>
<body>
<?php
// This is a PHP comment
echo "Hello, World!";
?>
</body>
</html>
