Difference between home_url() versus get_option('home')

Question

I need to echo out my website's URL. I read through WordPress Codex but I still do not understand, what is the difference between

<?php echo get_option('home'); ?>

versus

<?php echo home_url(); ?>

Is one "safer" to use? Which one should I use?

Answer 1

home_url比get_option（'home'）更快更安全，可选择使用home_url函数追加参数。

Answer 2

Both the functions will do the same thing but there is a difference in how they do it.

For instance home_url() will internally call get_option('home') and add appropriate protocols like http or https. And get_option('home') will return the raw value of your set URL without making any alternations.

Also, it is recommended that you use home_url() because its more secure.

Answer 3

I would stick to the function. It is a helper function that not only handles the option retrieval for you but sets http/https and (optionally) appends a path so no need to do the grunt work yourself.

Answer 4

使用wordpress预定义函数（如home_url（））比使用get_option（'home'）获取原始数据更安全;

Answer 5

Yes to both! (Is one faster/is one more secure)

Home_url() is both faster and more secure!

The answer lies in the behavior of each function you reference in the question:

Get_option goes through a controller to find the option with the name given.

While home_url is a built in function that returns the properly formatted url.
