phpst安装memcache扩展_在 Ubuntu/Debian 下安装 PHP7.3 教程

介绍

最近的 PHP 7.3.0 已经在 2018 年12月6日发布 GA，大家已经可以开始第一时间体验新版本了，这里先放出 PHP7.3 安装的教程以便大家升级。

适用系统： Ubuntu 18.04 LTS / Ubuntu 16.04 LTS ／ Ubuntu 14.04 LTS / Debian 9 stretch / Debian 8 jessie

更新内容

PHP7.3 的主要更新内容：

Implemented Flexible Heredoc And Nowdoc SyntaxesAllow a Trailing Comma in Function CallsJSON_THROW_ON_ERRORlist() Reference Assignmentis_countable Functionarray_key_first(), array_key_last()Argon2 Password Hash EnhancementsDeprecations

PHP 7.3 并没有带来特别激进的更新，同一天发布更新的 WordPress 5.0 也是第一时间带来了对 PHP7.3 的支持。

当然了 PHP 7.3 也带了性能提升，相比早期的 PHP 7.0 有了近 22% 的性能提升。同时 PHP 5.6 和 7.0 都即将失去 PHP 社区官方的支持，所以也是建议大家能尽快的升级到最新版本。

安装 PHP

Ondřej Surý 的 PHP PPA 为 Ubuntu 18.04/16.04/14.04 提供了 PHP7.2 版本，同时也有为 Debian 9/8 提供 PHP7.2 版本，因此 Ubuntu 是源于 Debian 所以基本可以通用，同时维护难度较低，软件源安装的 PHP 默认以 Unix Socket 的状态运行在 /run/php/php7.3-fpm.sock，比使用 TCP 以 localhost:9000 的方式性能更好。

值得一提的是 Ondřej Surý 是 Debian PHP 软件源的官方维护者之一，所以说稳定性和安全性基本上不是问题。

由于 PHP 7.3 是新出的版本势必有不少的兼容性问题，特别是国产的程序建议等待开发者通知再进行升级，一些 PECL 扩展可能也不会及时适配最新版。建议更新前提前做好备份准备。目前已知的是 WordPress 5.0 版本开始支持 PHP 7.3。
