php pseudo-static

Should we choose pseudo static or true static
1. There is no difference between using true static and false static for SEO
2. Using true static may cause hard disk damage and affect the forum performance
3. Using pseudo static will take up a certain amount of space Amount of CPU occupancy, heavy use will cause CPU overload
　4. The most important point is that we need to be static for SEO
　So:
　1. Using the true static method can be directly eliminated, because no matter how it is generated, it will affect the hard disk It's all very hurtful.
　2. Since the effect of true and false static is the same, we can choose pseudo static.
　3. However, extensive use of pseudo-static will cause CPU overload.
　4. So as long as we don’t use it in large quantities, it’s fine.
　5. Since static is only for SEO, we only need pseudo-static for SEO, and there is no need for users to use it.
　6. So we only need to use pseudo-static in the Archiver specially provided for SEO crawling.
　7. Thank you all for patiently reading my article.
8. If you have any questions or different opinions, please feel free to comment on pseudo-static and true static. There is an essential difference between true static and pseudo-static. Processing a pure HTML for browsing users and a PHP that calls multiple data have significantly less CPU usage than the former. I remember someone once said that the hard disk is frequently read and written when downloading HTML. He said this as if reading the database does not require reading and writing to the disk. What's more, there are a lot of cached scattered PHP that are also placed on the hard disk. Doesn't these reads require disk operations? ridiculous.
　The purpose can be achieved by reading a single html + image Flash and other attachments. Why bother reading the database, reading the php cache file, re-integrating the data output, and adding image Flash and other attachments? The CMS homepage does not require a lot of interaction, and the forum version should not be used here. On the contrary, what should be considered more is: beauty! compatible! Intuitive information! performance! And stability!

I am transferring a php pseudo-static implementation of four methods:

1 2 //Pseudo-static method one
3
4 // localhost/php100/test.php?id|1@action|2
5 $Php2Html_FileUrl = $_SERVER["REQUEST_URI"];
6 echo $Php2Html_FileUrl."
";// /php100/test.php?id|1@action|2
7 $Php2Html_UrlString = str_replace("? ","",str_replace("/", "", strrchr(strrchr($Php2Html_FileUrl, "/"),"?")));
8 echo $Php2Html_UrlString."
";// id| 1@action|2
9 $Php2Html_UrlQueryStrList = explode("@", $Php2Html_UrlString);
10 print_r($Php2Html_UrlQueryStrList);// Array ( [0] => id|1 [1] => action|2 )
11 echo "

12 foreach($Php2Html_UrlQueryStrList as $Php2Html_UrlQueryStr)
13 {
14 $Php2Html_TmpArray = explode("|", $Php2Html_UrlQueryStr);
