request will be repeated execution of the parse-compile-execute, and in practice, the PHP code in the server generally will not change, every time we request to perform some unnecessary operations, which directly affect the performance of PHP, We're going to come here and think about why we don't have to cache? There are already a lot of mature caching mechanism, in the implementation of PHP code should be more than enough, even if our PHP code will change, we can also use a mature algorithm to

According to IDC, in 2003, 75% of IT spending was spent on storage devices and storage networks. Data explosions in the Internet, E-commerce, bioinformatics, and personalized Web services have created a lot of data. The value of these data is estimated at billions of dollars. Most of the value of the data is not implemented because it waits for analysis, but if the data is corrupted or lost, recreating it will take months or years. Although some data is constantly being retrieved (such as Custom
