What are the best practices for dynamically generating form fields based on database entries in PHP to avoid unexpected characters in input names?

When dynamically generating form fields based on database entries in PHP, it's important to sanitize the database entries to avoid unexpected characters that could potentially lead to security vulnerabilities or errors. One way to do this is by using PHP's `htmlspecialchars()` function to escape special characters in the input names before outputting them in the form fields. 

<?php
// Assume $dbEntries is an array containing database entries for form field names

foreach ($dbEntries as $entry) {
    $fieldName = htmlspecialchars($entry); // Sanitize the database entry
    echo '<input type="text" name="' . $fieldName . '" />';
}
?>
