Linux compiles and installs the php libevent extension method. Implementing high-performance network services in php programming requires the support of the libevent extension library. This article installs the libevent extension library by compiling source code.
To write high-performance network services in PHP, you need to install the libevent extension. 1. Download libevent extension: http://pecl.php.net/package/libevent 2. After decompression, start compiling $ cd libevent-version $ /usr/local/php/bin/phpize $ ./configure --with-php-config=/usr/local/php/bin/php-configAn error is reported, and the error shows that the re2c version is too low. re2c, PHP's lexical parser, official website: http://re2c.org/, download the latest version, and the compilation is completed. Continue to compile the PHP extension just now, and still get an error error: Cannot find libevent headers Until now, the directory of libevent must not have been found. Check locally whether libevent is installed, Finally found the libevent-2.0.12-stable directory in a directory. 3. If it is not installed, you need to install libevent first. wget http://cloud.github.com/downloads/libevent/libevent/libevent-2.0.20-stable.tar.gz tar zxvf libevent-2.0.20-stable.tar.gz cd libevent-2.0.20-stable/ ./configure --prefix=/usr/local/libevent-2.0.20-stable/ make make install cd ../4. Continue to compile extensions $ cd libevent-0.0.5 $ /usr/local/php/bin/phpize $ ./configure --with-php-config=/usr/local/php/bin/php-config --with-libevent=/usr/local/libevent-2.0.20-stable $ make && make installThis time the compilation passed. |

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

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.
