What is the best practice for dynamically reading and filling HTML inputs using PHP?

When dynamically reading and filling HTML inputs using PHP, the best practice is to use a combination of PHP and HTML to generate the input fields dynamically. You can use PHP to retrieve data from a database or any other source, and then populate the input fields with this data by setting the 'value' attribute of the input tags.

<?php
// Assume $data is an array containing the values to fill the input fields
$data = array(
    'name' => 'John Doe',
    'email' => 'johndoe@example.com',
    'age' => 30
);
?>

<form>
    <input type="text" name="name" value="<?php echo $data['name']; ?>">
    <input type="email" name="email" value="<?php echo $data['email']; ?>">
    <input type="number" name="age" value="<?php echo $data['age']; ?>">
</form>
