Web 开发与PHP 杨亮 为什么要从事Web开发 • 互联⺴⽹网是发展最好的⾏行业 • 会有成千上万⼈人使⽤用你的产品 • 相对容易找到⼯工作 • 赚钱最多的⼯工作之⼀一 • 可以解决⾃自⼰己的实际问题 • 可以告诉家⼈人我在做什么 • 。。。。 Web产品流程 ⽤用户 PM UE RD FE QA OP PM: Project & Marketing (IIS) 后端脚本 （PHP） （JSP） （ASP） 数据库 （MySQL） （Oracle） （Access） HTTP 请求 对应⽂文件 获取数据 返回数据 返回⻚页⾯面 返回⻚页⾯面 请求⻚页⾯面 服务器端 客户端 html css javascript html css javascript Web开发⼈人员需要关注 后端脚本 （PHP） （JSP） （ASP） cnbeta.com/articles/182533.htm 什么是 PHP Personal Home Page 脚本语⾔言:编写+运⾏行 很像C语⾔言，但是简单很多 满屏都是$$$$$$$$$ 开源软件 跨平台 将程序嵌⼊入到HTML中执⾏行 弱语法：没有指针，不约束变量类型，⼤大量内置函数 为什么要学PHP • ⼤大家都在⽤用 • 社会需求旺盛 • 可以深⼊入可以浅出

PHP基本语法 —条件、循环、函数 杨亮 程序的基本结构 输⼊入 输出 程序 运算（+ - x / & | ! …） 逻辑（条件、循环、递归） 辅助（变量、数组、函数） ⼩小测验 ⽤用你熟悉的程序找出 1~1000中的所有质数 我们直接看代码好了 1 php 2 if( $totalqty == 0 ) 3 echo 'You did not order anything align="center">Distance 6 Cost 7 8 php 9 $distance = 50; 10 while ($distance <= 250) { 11 echo " 12 " 增强程序的⼀一致性 PHP中的代码重⽤用 • 将其他⽂文件中的html或者php代码引⼊入到本⽂文件 • require()与include(); • require_once()与include_once(); • 可以引⼊入其他的函数库，或者代码⽚片段 1 php 2 //reusable.php 3 echo 'Here is a very simple PHP statement
