第 1 章
PHP
介绍
PHP
是一种用于创建
HTML
内容的、容易上手且功能强大的语言。本章涵盖了
PHP
语
言的基本背景，主要描述其特性、历史、运行平台以及配置方法。同时会简要介绍一些
处理常规任务的
PHP
程序，例如数据处理、与数据库交互、创建图形界面等。
PHP
可以做什么
PHP
主要有以下两个方面的应用。
服务器端编程
PHP
最初被设计用来创建动态
Web
内容，现在它最擅长的还是这个任务。你需要
PHP
解析器，并需要通过一台
Web
服务器输出编码好的文件，从而生成
HTML
内容。
PHP
语言也因在通过连接数据库输出动态内容、
XML
文件、图形界面、
Flash
动画、
PDF
文件等很多方面有出色的表现，而变得非常流行。
命令行编程
PHP
可以在命令行上运行脚本，很像
Perl
、
awk
或者
UNIX shell
命令等。你可以使
用命令行脚本执行备份操作、分析日志、
CRON
作业任务等系统管理任务（作为非
可视化的
PHP
任务）。
不过本书将重点讲解第一个方面 ：使用
PHP
语言开发动态
Web
内容。
PHP
可以运行在所有主流的操作系统上，包括
Linux
、
Free BSD
、
Ubuntu
、
Debian
、
Solaris
等
UNIX
变种系统，以及
Windows
和
macOS
。
PHP
可以用在所有主流的
Web
服
务器上，包括
Apache
、
Nginx
、
OpenBSD
服务器等。它甚至还能用于快速发展中的云环
境，例如，
Azure
和
Amazon
。
