这两个Wordpress函数有什么区别？

Question

What is the difference between this two Wordpress function:
plugin_dir_url vs plugin_dir_path .
Thanks for your help.

Answer 1

Return values of the Two mentioned functions

1. plugin_dir_path( FILE ) returns the servers filesystem directory path pointing to the current file, ie something along the lines of

/home/www/your_site/wp-content/plugins/your-plugin/includes/

This can be used for loading PHP files.

2. plugin_dir_url() behaves in a very similar fashion to plugins_url(). It also returns a web address, but with a trailing slash, ie something along the lines of

http://example.com/wp-content/plugins/

This can be used to load images, stylesheets, JS and the like
