1. Learn HTML and CSS in one week.

2. you can learn Javascjrit in two weeks.

Jquery just wraps Javascjrit, nothing new.

3. Learning Jquery for a week can definitely be done.

If you learn the first three things and can make simple pages, then you can learn ajax quickly. Ajax is not a technology, but a concept. It is a comprehensive application of the previous technologies, and it is nothing more than two operations: get and post.

4. Learn ajax for three days.

5. It depends on the ability of php. It is not difficult to learn php if you can finish it in the estimated time above. If making a simple blog is the standard, it will take a month to learn php.

6. Learn mysql for two weeks (learn database knowledge the week before and sql statements the week after).

The above time is quite sufficient, and those with good ability can complete all their studies within one month.

Every technology is easy to use, but if you want to master or cook some experience, you must go through N projects and hone it slowly.

After you learn the above, you can spend three weeks practicing your personal website, and then you can make a hilarious website.

There is a shortcut: after learning html and css, build a website directly with cms.

I'd be happy to answer your questions. If you have any questions in your study, please feel free to ask them.
