php小代码分享

众所周知,最好的学习方法就是写博客或日记,在我最近学习php的$_POST表单函数时,又正好那所学的做了一个简单的邮箱统计申请。各位大佬如果有好的建议欢迎提建议,非常想要大家所提供的建议。

首先介绍以下项目(声明,这一切都是为了自我学习):

新学期开学季,有很多新生入校,学校社团也开始招生,为了方便统计和审核新生信息,利用php做一个表单系统。

需要工具

1.web服务器

2.SMTP第三方邮箱账号

3.2个php邮箱配置文件

首先设计表单(index.html):

这里我只提供主要核心代码


<div id="div">
        <form class="center" action="sendmail.php" method="post">
            <h1 class="h1 center">银职社团</h1>
            <h1 class="h1 center">申请入社请求</h1>
            <hr />
            <div style="width: 80%;height:auto;margin: auto;overflow:hidden">
                <h1 style="text-align: center;margin-bottom: 10px;">目前支持的社团及介绍</h1>
                
                <ul >
                    <li style="float: left;"><a class="a" href="#">Info科技社介绍</a></li>
                    <li style="float: left;"><a class="a" href="#">中华围棋社</a></li>
                </ul>

这是第一个文件,具体css样式自行设计

创建第二个文件在同目录下(sendmail.php):

由于上传大小有限,我在这采用文件浏览

云盘下载

文件参考下载地址

最后一个文件(smtp.class.php):

}

这样基本就可以使用了
