解决php include中绝对路径与相对路径的问题
在使用php的include/require/include_once/require_once时有时会碰到路径困扰,尤其是重复包含或嵌套包含时,一个有效的办法是定义文件“根”,如:
if (!defined('KEIYICLASS_ROOT')) { define('KEIYICLASS_ROOT', dirname(__FILE__) . '/'); } // core classes include_once(KEIYICLASS_ROOT."core/date.php"); include_once(KEIYICLASS_ROOT."core/db.php"); include_once(KEIYICLASS_ROOT."core/init.php"); include_once(KEIYICLASS_ROOT."core/sys.php");

Microsoft's Windows 11 2022 Update (22H2) enables CoreIsolation's memory integrity protection by default. However, if you are running an older version of the operating system, such as Windows 11 2022 Update (22H1), you will need to turn this feature on manually. Turn on CoreIsolation's Memory Integrity feature in Windows 11 For users who don't know about Core Isolation, it's a security process designed to protect basic core activities on Windows from malicious programs by isolating them in memory. This process, combined with the memory integrity feature, ensures

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. The root user can execute important system commands and edit system files, which ordinary users cannot do. In this guide, I'll explore the Ubuntu root user, how to log in as root, and how it differs from a normal user. Notice

Core has two meanings in computers: 1. The core, also known as the core, is the most important component of the CPU. All calculations, accepting storage commands, and processing data of the CPU are performed by the core; 2. Core, core is Intel's processor Name, Core is the processor brand launched by Intel after the Pentium processor. It has currently released twelfth generation Core processors.

Both root and alias can be defined in the location module, and are used to specify the real path of the requested resource, for example: location/i/{root/data/w3;} requests http://foofish.net/i/top.gif When this address is used, the corresponding real resource in the server is the /data/w3/i/top.gif file. Note: The real path is the value specified by root plus the value specified by location. And alias is just like its name. The path specified by alias is the alias of location. No matter how the value of location is written, the real path of the resource is the path specified by alias, such as

0x01 Background of the article Recently, the storage of a business system of the author's company is approaching the limit, and the server will soon be unable to run. Because the business system A contains multiple subsystems A1, A2, A3... An, the middle of these subsystems Due to design reasons, the stored files are all stored in the same parent directory. The only difference is that the names of files and folders generated by different subsystems all start with the name of the subsystem. For example, the files generated by the A1 subsystem are all named A1xxxxxx, and the file names generated by the A2 subsystem are all A2xxxxx. Now we need to delete the historical files of some of these subsystems to free up server space. Dozens of terabytes of data are stored together. Manual deletion will definitely not show up. We can only use program automation.

1. Taking CentOS as an example, after logging in, modify /etc/passwd and /etc/shadow, change the root starting on the first line to a new user name (such as admin), and save through wq! after modification. 2. After modifying and saving, it will take effect after restarting the server. You can check the permissions of the file and see that the account column has changed to admin, as follows: Note: The default user with the highest administrative authority in Linux is root, uid is 0. Only uid is recognized in the system, so as long as uid is 0, the system is regarded as the highest administrative user. However, there may be certain problems with applications. Some software uses the root user by default, so if you have limited understanding of software applications,

When we write web pages using PHP, sometimes we need to include code from other PHP files in the current PHP file. At this time, you can use the include or include_once function to implement file inclusion. So, what is the difference between include and include_once?

The benefits of rooting your phone: 1. You can back up the system; 2. You can use advanced programs; 3. You can modify and delete system programs; 4. You can install programs on the SD card; 5. You can modify system fonts, etc. Disadvantages: 1. After the mobile phone is rooted, it is easy to be invaded by Trojan viruses; 2. System damage may occur due to incompleteness and software compatibility issues; 3. After the mobile phone is rooted, the software mistakenly deletes system files, causing system errors; 4. There is a risk that user privacy will be leaked after rooting the phone, etc.
