Simple page buffering technology (3)_PHP tutorial
The content.php3 file is used to handle dynamic pages. Users can read a data file through content.php3?page=id number. I won’t go into the specific method. As long as you know that each data file has a different ID number, the method content.php3?page=id number can uniquely identify a data file.
Lines 1-3 generate temporary file names. Replace '?', '&' and other characters with '_'.
Line 4 determines whether the temporary file name exists. If so, execute lines 18-22 and end.
Lines 6-13 determine which of the file modification time and temporary file related to generating dynamic pages is updated, and set the regeneration flag. Use filemtime() here to get the last modification time.
Lines 24-41 use template classes to generate dynamic results and place them in variables. Regarding the processing of templates, please refer to the article "Template, PHPLIB Processing Method".
Lines 43-50 generate temporary files. The file is locked here to prevent write conflicts.
Line 51, output the results.
This is how I handled it, you can modify it yourself.
Buffering is a meaningful technology that can improve access speed and reduce system consumption. However, there may be many methods, and everyone is free to use them.

Log in to Ubuntu as superuser
Mar 20, 2024 am 10:55 AM
In Ubuntu systems, the root user is usually disabled. To activate the root user, you can use the passwd command to set a password and then use the su- command to log in as root. The root user is a user with unrestricted system administrative rights. He has permissions to access and modify files, user management, software installation and removal, and system configuration changes. There are obvious differences between the root user and ordinary users. The root user has the highest authority and broader control rights in the system.

Convert VirtualBox fixed disk to dynamic disk and vice versa
Mar 25, 2024 am 09:36 AM
When creating a virtual machine, you will be asked to select a disk type, you can select fixed disk or dynamic disk. What if you choose fixed disks and later realize you need dynamic disks, or vice versa? Good! You can convert one to the other. In this post, we will see how to convert VirtualBox fixed disk to dynamic disk and vice versa. A dynamic disk is a virtual hard disk that initially has a small size and grows in size as you store data in the virtual machine.

However, as disk capacity expands, your computer's performance may be slightly affected. Fixed disks and dynamic disks are commonly used in virtual machines
