How can the EV A principle be applied to separate HTML output from PHP logic to improve code readability and security in PHP projects?

To separate HTML output from PHP logic in PHP projects, the EV A (Echo, View, Assign) principle can be applied. This involves keeping PHP logic separate from HTML markup by assigning data to variables in PHP, then echoing those variables within the HTML markup. This not only improves code readability but also enhances security by reducing the risk of code injection vulnerabilities. 

<?php
// Assign data to variables
$title = "Welcome to my website";
$message = "Hello, user!";

// HTML markup with variables echoed
?>
<!DOCTYPE html>
<html>
<head>
    <title><?php echo $title; ?></title>
</head>
<body>
    <h1><?php echo $message; ?></h1>
</body>
</html>
