What is pseudo-static? What is the significance of using pseudo-static in PHP?

There are many friends who are doing php development work. Many times you may hear phppseudo-static. Maybe many of them don’t know what php pseudo-static is. So today we will take you to understand what PHP pseudo-static is, and what is the significance of PHP using pseudo-static?

Pseudo-static is relative to real static.

1. What is static technology?

The so-called static means that there is no question mark in the address. Pseudo-static, also known as URL rewriting, is a dynamic URL that looks like a static URL. In other words, dynamic web pages remove the parameters of dynamic web pages by rewriting the URL method, but there is no need to implement rewritten pages in the actual web page directory.
2. Why use pseudo-static technology?
One of the biggest features of Web applications is statelessness. When one page jumps to another page, all parameters on this page will be discarded, so dynamic pages generally use URL addresses to save their Parameters, like:

www.attjs.net/essay.asp?id=1

In this way, when the search engine indexes the page, it may enter a dead loop due to question marks. (Previously Dongwang There is such a loophole that the spider cannot get out), so in many cases the address with a question mark will not be entered, which reduces the efficiency of page collection. In this case, wouldn't it be better to use a URL without a question mark to allow the search engine to include your own webpage? indeed. The URL of a static web page happens to not have a question mark, so we have to fake it for the sake of SEO and improve the efficiency of website inclusion.
1. About the use of pseudo-static

Some users think that the actual number of included pseudo-static and true static will be very different. In fact, this is not the case. From your personal perspective , can you judge whether a post is truly static or pseudo-static?
It is probably difficult to tell, because the so-called static means that there is no question mark in the address, and the address without question mark is static, no matter what it is. Is it real or fake? Can search engines see it? So, whether it is real or fake, it is actually the same to search engines. The search engine does not say that yours is fake and I will not include it. You. 　
In the final analysis, why do search engines not include URLs with question marks? Because search engines are afraid of entering an endless loop due to question marks, so many times addresses with question marks will not be included. For search engines, pseudo-static is actually static, because there is no question mark in the address, so there is no saying that true static is included more than pseudo-static.


2. About the disadvantages of pseudo-static

Of course, as the author of an article said, "If the traffic is slightly larger and pseudo-static is used, the CPU usage will be overloaded. I have more than 300 people online at the same time and hang up. When I do not use pseudo-static, the CPU will be overloaded." Even if more than 500 people are online, my ISS number is 1,000. This is indeed the case. Since pseudo-static uses regular expressions instead of real addresses, the responsibility for determining which page to display is transferred from direct specification to the CPU. Therefore, the increase in CPU occupancy is indeed the biggest disadvantage of pseudo-static.


Explanation:

1. Using the true static method can directly Excluded, because no matter how it is generated, it will be very harmful to the hard disk. ​ 2. Since the effect of true and false static is the same, we can choose pseudo-static. ​
3. However, large-scale use of pseudo-static will cause CPU overload. ​

​ 4. So we only need to not use it in large quantities. ​

​ 5. Since static is only for SEO, we only need pseudo-static It’s enough for SEO, it doesn’t need to be used by users. ​

​ 6. So we only need to use pseudo-static in the Archiver specially provided for SEO crawling
