php入門教程-PHP上傳文件和發(fā)郵件
Jun 08, 2016 pm 05:27 PM/*
至于發(fā)郵件就更加簡單,可以使用mail()函數(shù)mail("收件人地址","主題","正文","From:發(fā)件人 Reply-to:發(fā)件人的地址");
不過mail()需要服務(wù)器的支持,在WINDOWS下還需要配置SMTP服務(wù)器,一般來說外面的LINUX空間都行。
好像上傳文件和發(fā)郵件比ASP簡單很多,只要調(diào)用函數(shù)就可以了。ASP還需要用到服務(wù)器的不同組件比如FSO、JMAIL什么的。
下面來看文件上傳實例
傳文件表單必須加上enctype="multipart/form-data"和
?代碼如下 | 復(fù)制代碼 |
$f=&$HTTP_POST_FILES['file']; $dest_dir='uploads';//設(shè)定上傳目錄 $dest=$dest_dir.'/'.date("ymd")."_".$f['name'];//我這里設(shè)置文件名為日期加上文件名避免重復(fù) $r=move_uploaded_file($f['tmp_name'],$dest); chmod($dest, 0755);//設(shè)定上傳的文件的屬性 |
上傳的文件名為date("ymd")."_".$f['name'] ,可以在以后插入到數(shù)據(jù)庫教程的時候用到,PHP實際上是把你上傳的文件從臨時目錄移動到指定目錄。
move_uploaded_file($f['tmp_name'],$dest);這是關(guān)鍵
