Examples
#1 Run code for the child theme only
Suppose we are writing a theme and we only need to execute PHP code when our theme is used as a parent theme, i.e. a child theme is defined and used:
if( is_child_theme() ){
echo 'The code is for the child themes, not the parent;
} #2 Alternative detection if is child theme.
WARNING: This function uses the TEMPLATEPATH and STYLESHEETPATH constants internally. If calling from a plugin, such as during plugin activation, there’s a chance these will be undefined. It is better to use:
get_template_directory() !== get_stylesheet_directory()
