</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">获取ThinkPHP的方式有<span style="color: black;">非常多</span>，<span style="color: black;">不外</span>我<span style="color: black;">举荐</span><span style="color: black;">大众</span>从ThinkPHP官网（http://www.thinkphp.cn）获取最新版本，进入ThinkPHP官网，点击上方导航栏下载，找到ThinkPHP3.2.3完整版并下载。</p>

</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在Web根目录下新建think文件夹，并将文件解压到think文件夹，<span style="color: black;">而后</span><span style="color: black;">拜访</span>localhost/think，<span style="color: black;">就可</span>看到默认ThinkPHP首页内容。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="https://p3-sign.toutiaoimg.com/40090002f62b2561c651~noop.image?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1729831800&x-signature=M3kc4va6P1ErB%2Fr1A0AIi%2Fcg1eg%3D" style="width: 50%; margin-bottom: 20px;"></p>

</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">ThinkPHP是一个快速、兼容<span style="color: black;">况且</span>简单的轻量级国产PHP<span style="color: black;">研发</span>框架，<span style="color: black;">运用</span>面向对象的<span style="color: black;">研发</span>结构和MVC模式（关于MVC模式我将单独发教程）。<span style="color: black;">此刻</span><span style="color: black;">广泛</span><span style="color: black;">运用</span>的是3.2.3和5.0.x版本，前者<span style="color: black;">重点</span>面向普通Web<span style="color: black;">研发</span>，后者<span style="color: black;">重点</span>面向API<span style="color: black;">研发</span>，<span style="color: black;">咱们</span><span style="color: black;">首要</span>学习ThinkPHP3.2.3版本的<span style="color: black;">研发</span>。</p>
