How can PHP be used to dynamically generate file names based on user selections in a form?

When a user makes selections in a form, PHP can be used to dynamically generate file names based on those selections. One way to achieve this is by using PHP to concatenate the user selections into a string and then use that string as the file name. This can be done by capturing the form data using $_POST or $_GET, and then manipulating the data to create a unique file name. 

<?php
// Assuming form data is submitted via POST method
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Capture user selections from the form
    $selection1 = $_POST['selection1'];
    $selection2 = $_POST['selection2'];
    
    // Concatenate user selections to create a unique file name
    $file_name = $selection1 . '_' . $selection2 . '.txt';
    
    // Use the generated file name for file operations
    $file = fopen($file_name, 'w');
    // Write data to the file, close file, etc.
}
?>
