如何在十天内学会php之第十天
学习目的:学会用PHP上传文件和发邮件
上传文件表单必须加上 enctype="multipart/form-data"
和 <input type="file" name="file">
下面看一下代码:
$f=&$HTTP_POST_FILES['file'];
$dest_dir='uploads';//设定上传目录
$dest=$dest_dir.'/'.date("ymd")."_".$f['name'];//我这里设置文件名为日期加上文件名避免重复
$r=move_uploaded_file($f['tmp_name'],$dest);
chmod($dest, 0755);//设定上传的文件的属性
上传的文件名为date("ymd")."_".$f['name'] ,可以在以后插入到数据库的时候用到,PHP实际上是把你上传的文件从临时目录移动到指定目录。move_uploaded_file($f['tmp_name'],$dest);这是关键
至于发邮件就更加简单,可以使用mail()函数
mail("收件人地址","主题","正文","From:发件人\r\nReply-t发件人的地址");
不过mail()需要服务器的支持,在WINDOWS下还需要配置SMTP服务器,一般来说外面的LINUX空间都行。
好像上传文件和发邮件比ASP简单很多,只要调用函数就可以了。ASP还需要用到服务器的不同组件比如FSO、JMAIL什么的。
十天学会PHP说到这里了,PHP入门可以是十天,但是精通决不是十天啊,还需要大家自己去研究。
