    The get_stylesheet() function in WordPress is a useful function for theme developers. Here's a detailed explanation of its function and sample usage:

    Function Signature:

    get_stylesheet(): string
    

    Function Description:

    • Purpose: get_stylesheet() is used to retrieve the name of the current stylesheet in use by the WordPress theme.
    • Usage Context: This function is primarily used in theme development, where understanding the active stylesheet is crucial for loading styles, customizing theme appearances, and more.
    • Operation: When called, get_stylesheet() returns the directory name of the current theme's stylesheet. It's important to note that in WordPress, the terms "template" and "stylesheet" can have different meanings. The "template" refers to the parent theme in case of a child theme setup, whereas the "stylesheet" refers to the actual theme in use, which could be a child theme.
    • Common Use Cases: This function is particularly handy in scenarios where you need to enqueue style files, access specific theme files, or when working with child themes in WordPress.

    Return Value:

    • Type: string
    • Description: The function returns the name of the stylesheet. This is essentially the folder name where the stylesheet files are located.

    Sample Usage:

    <?php
    // Example of using get_stylesheet()
    function theme_enqueue_styles() {
        // Get the current stylesheet name
        $stylesheet = get_stylesheet();
    
        // Enqueue a style file specific to the current theme
        wp_enqueue_style( 'theme-style', get_stylesheet_directory_uri() . '/style.css', array(), null );
    
        // Conditional logic based on the stylesheet name
        if ($stylesheet == 'my-child-theme') {
            // Do something specific for 'my-child-theme'
        }
    }
    add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' );
    ?>
    

    In this example, get_stylesheet() is used within a function hooked to wp_enqueue_scripts action. It retrieves the name of the active theme's stylesheet and uses it to enqueue the main style file. Additionally, it includes a conditional statement that executes a block of code only if the active theme is 'my-child-theme'. This kind of usage is typical in WordPress theme development, especially when handling child themes.
