I. What is ZendCache?
Let's take a look at how php runs. after a php script is sent to the server, the server searches for the corresponding file from the disk, compiles the script, runs the script, and finally sends the result. The time spent consists of searching for files, opening files, reading files, and compiling files. ZendCache is a php script high-speed Cache that stores the compilation results of the php script file that has just been executed in the memory of the Web server. if someone requests this page again next time, it can be sent out quickly. This eliminates the time required for the server to compile a script every time the user requests the php file. At the same time, it does not take time to search for and read php files from the disk. Therefore, the server speed can be greatly improved.
Currently, ZendCache can only run on Linux (glibc 2.1), Solaris 2.6, FreeBSD 3.4, and 4.0. Unfortunately, it does not support Windows systems currently.
