=== WP filter in nested HTML table ===
Hello Dolly is a good sample of simple working plugin.
If you are interested in understanding or developing WordPress, sooner or later you might want to trace do_action(‘template_redirect’). With the knowledge from function’s documentation, you know $wp_filter is involved. You may show array using val_dump or print_r, but it will take time for human eyes to read array in plain text directly. This plugin will show $wp_filter content in nested html table style for your easy reference. When activated you will see immediate result of your admin screen on every page.
