1. First open the apache configuration file httpd.conf, and remove the # in front of #Include conf/extra/httpd-vhosts.conf to enable the virtual host function
2. Configure localhost first to avoid problems when accessing localhost later. The root directory of my wamp project is D:wampwww. Add the following information to the end of the configuration file httpd-vhosts.conf under apache's apache/conf/extra;
DocumentRoot "D:/wamp/www"
ServerName localhost AllowOverride None
Order allow , deny
Allow from all
3. Configure virtual hosts for other projects: For example, configure www.zf.com, open the link to directly access the D:/wamp/www/zf/public directory. "DirectoryIndex Index.php" means that accessing the directory to open the "Index.php" file
documentroot "D:/WAMP/WWW/ZF/PUBLIC"
Servername www.zf.com
directoryINDEX INDEX. pHP d "D :/wamp/www/zf/public ">
Options Indexes FollowSymlinks
Allowoverride None
Order Allow, DENY
4, modify C: WindowsSystem32Driver Host file under SETC, open it with a notepad, add 127.0.0.1 www .zf.com , just restart apache.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.
