What are the recommended methods for handling output context and character encoding when including arrays in PHP templates?

When including arrays in PHP templates, it is important to properly handle output context and character encoding to ensure that the data is displayed correctly. One recommended method is to use htmlspecialchars() function to encode the array values before outputting them in the template. This helps to prevent any potential security vulnerabilities such as cross-site scripting attacks. 

<?php
// Sample array with potentially unsafe data
$array = [
    '<script>alert("XSS attack!")</script>',
    'Safe data'
];

// Encoding array values before outputting in the template
foreach ($array as $value) {
    echo htmlspecialchars($value, ENT_QUOTES, 'UTF-8') . '<br>';
}
?>
