What are some recommended approaches for managing and deleting dynamically generated form fields in PHP?

When dynamically generating form fields in PHP, it is important to have a way to manage and delete these fields as needed. One approach is to assign unique identifiers to each dynamically generated field and store them in an array. Then, when deleting a field, you can remove it from the array based on its identifier. This allows for easy management and manipulation of dynamically generated form fields. 

// Sample code for managing and deleting dynamically generated form fields in PHP

// Initialize an array to store dynamically generated field identifiers
$field_identifiers = [];

// Loop to dynamically generate form fields with unique identifiers
for ($i = 1; $i <= 5; $i++) {
    $field_identifier = 'field_' . $i;
    $field_identifiers[] = $field_identifier;
    echo '<input type="text" name="' . $field_identifier . '" />';
}

// Code to delete a dynamically generated field based on its identifier
$delete_field_identifier = 'field_3';
$key = array_search($delete_field_identifier, $field_identifiers);
if ($key !== false) {
    unset($field_identifiers[$key]);
    // Additional code to remove the corresponding form field from the HTML
}
