gzip command
Reducing file size has two obvious benefits. One is that it can reduce storage space, and the other is that it can reduce the transmission time when transferring files over the network. gzip is a command commonly used in Linux systems to compress and decompress files. It is both convenient and easy to use.
Syntax: gzip [options] Compressed (decompressed) file name. The meaning of each option of this command is as follows:
-c writes the output to the standard output and retains the original file. -d Decompress the compressed file. -l For each compressed file, display the following fields: size of compressed file; size of uncompressed file; compression ratio; name of uncompressed file -r Recursively search the specified directory and compress or decompress all files in it. -t test, check whether the compressed file is complete. -v For each compressed and decompressed file, display the file name and compression ratio. -num adjusts the compression speed with the specified number num, -1 or --fast indicates the fastest compression method (low compression ratio), -9 or --best indicates the slowest compression method (high compression ratio). The system default value is 6. Command example:
gzip *% Compress each file in the current directory into a .gz file. gzip -dv *% Decompress each compressed file in the current directory and list detailed information. gzip -l *% displays detailed information about each compressed file in Example 1 without decompressing it. gzip usr.tar% compresses the tar backup file usr.tar, and the extension of the compressed file is .tar.gz.
The above introduces the complete list of decompression commands under eoiioe Linux, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
