How can you ensure that the content of a "File-Input" field remains after submission in PHP?

To ensure that the content of a "File-Input" field remains after submission in PHP, you can use the $_FILES superglobal array to store the file information and then re-populate the input field with the file name after submission. 

<?php
$file_name = isset($_FILES['file']['name']) ? $_FILES['file']['name'] : '';
?>

<form method="post" enctype="multipart/form-data">
    <input type="file" name="file" value="<?php echo $file_name; ?>">
    <input type="submit" name="submit" value="Submit">
</form>
