How can PHP beginners ensure their code follows best practices to prevent errors in browsers?

To ensure that PHP code follows best practices and prevents errors in browsers, beginners should use proper syntax, avoid deprecated functions, sanitize user input to prevent security vulnerabilities, and use error handling techniques to catch and handle any issues that may arise. 

<?php

// Example of using proper syntax
$variable = "Hello, World!";

// Example of avoiding deprecated functions
$new_array = array(); // Instead of $new_array = [];

// Example of sanitizing user input
$user_input = $_POST['input'];
$clean_input = htmlspecialchars($user_input);

// Example of error handling
try {
    // Some code that may throw an error
} catch (Exception $e) {
    echo "An error occurred: " . $e->getMessage();
}

?>
