Purpose

The PHP code snippet defines a set of functions for managing flash messages in a session. Flash messages are temporary messages that are displayed to the user and then automatically disappear.

Functions

• set_flash(): Sets a flash message in the session with the given options.
• clear_flash(): Clears the flash message from the session.
• get_flash(): Retrieves the flash message from the session.
• get_classes(): Returns an array of CSS classes that should be used to display the flash message.

Usage

To use the functions, first call set_flash() with an array of options. Then, call get_flash() to retrieve the flash message. Finally, call clear_flash() when you are finished with the flash message.

Example

// Set a flash message
set_flash(['message' => 'That worked']);

// Get the flash message
$flash = get_flash();

// Display the flash message
echo '<div class="' . implode(' ', get_classes($flash)) . '">' . $flash['message'] . '</div>';

// Clear the flash message
clear_flash();

Options for set_flash()

• message The message to display to the user.
• type One of 'alert', 'notice', or another custom type.
• is_closeable Whether the message can be closed by the user.
• is_persistent Whether the message should persist for the entire session.
• display_for How many seconds to display the message before auto-closing.

Notes

• The display_for option is not implemented in the current code.
• The get_classes() function returns an array of CSS classes based on the options specified in set_flash().
• The flash message is stored in the session variable $_SESSION['flash'].
