What does this code do?

    Hi,

    This is the code from WooCommerce documentation: (https://docs.woocommerce.com/document/create-a-plugin/)

    /**
 * Check if WooCommerce is active
 **/
if ( in_array( 'woocommerce/woocommerce.php', apply_filters( 'active_plugins', get_option( 'active_plugins' ) ) ) ) {
    // Put your plugin code here
}

    I understand what this code does, but I can not understand why call to apply_filters(…) is required? Just using get_option( ‘active_plugins’ ) and then looking through it seem enough.

    Thanks,
    Rudolf

    I prefer to use:

    
if( class_exists( 'WooCommerce' ) ) {
    // Put your plugin code here
}

    That way it also works if WooCommerce is installed in a different directory. E.g. when I switch between two instances of WooCommerce during testing, like plugins/woocommerce-3.5.2 or plugins/woocommerce-2.6.14
