I do not understand how to implement a natural language processing system by using PHP + JavaScript + MySQL.

In my case, I would like to develop a text analysis and visualization technique for analyzing text contents from an English passage or comprehension that given on the website.

The Website is for students to login and answer the reading comprehension.

Several text analysis techniques such as tag cloud, word tree, and visual word has been found online. But I'm still do not understand how to implement them.

Tag cloud provides insights about the statistical occurrences of words?

Word tree gives a visualized organization of sentences in a passage?

Visual word gives the meanings of words from a passage?

In particular, I would like to either using all visualization techniques from above OR only use 2 techniques combined for visualizing the textual contents of passages in the reading comprehension for my system.

Please be kindly guide me to start this web system development, I will appreciate for the algorithm provided too.

This sounds like a serious task; but your tags say PHP and JavaScript. Are you serious? I don't think so. You question does not uncover the essence of the problem, just key words, but it looks like you don't understand it yourself, neither you understand power of computing languages you mentioned and your own capabilities. Also, it looks like you mix up unrelated issues: language processing and Web development. Which part seems to be a problem for you?

I would be glad to know I'm wrong. If it is so, show you understand things by explaining the essence of the problem, otherwise — forget it.

Sorry to confuse you. I am looking a web system by using PHP + JavaScript. The main issue is how to display the visualization for analyzing the text content from an English comprehension.

For example, a web site has 5 short passages, users would like to search a passage relate to the keywords they want, they can view the visualization to select the keywords, and show the passage from my database.

Thank you for your note.
You did not confuse me. I tried to hint, that those languages are too weak for serious development.
There are a lot of warning against PHP. This is rudimentary, good to do relatively simple server-side development, the benefit is availability in most hosting providers. For server-side power you may need something better, at least Python, but real powerful would be ASP.NET. As you're going to use Javascript on client side, this is not so critical, it would not help you to do text analysis, etc.
