How can PHP beginners avoid displaying variables in input fields in PHP forms?

PHP beginners can avoid displaying variables in input fields in PHP forms by using the `htmlspecialchars()` function to escape the variable values before displaying them in the input fields. This function will convert special characters to HTML entities, preventing any potential XSS attacks. By implementing this simple step, beginners can enhance the security of their PHP forms and protect user input data. 

<?php
// Escape the variable value before displaying it in the input field
$value = htmlspecialchars($variable, ENT_QUOTES);
?>
<input type="text" name="input_field" value="<?php echo $value; ?>">
