有时我们为了方便、安全、快速,会把上传的文件单独放一台主机用二级域名访问,但是PHP如何把上传的文件放到另外一台主机呢?这就要跨域跨主机上传了,现在我们用实例来告诉你如何实现.

如何跨网域跨主机跨server上传文件?一般最基本的上传方式是:

1.使用者把文件上传到 web server

2. web server 把上传的文件 利用 move_uploaded_file() 函式,将档案移到指定的文件夹内.

但是,有时候我们需要把上传的档案放到另一台专门放文件的 file server,这时候,就无法利用 move_uploaded_file() 去搬移文件了,而需要利用 ftp 去传送文件至 file server,方法很简单...直接看程式码:

<?php
$file = $_FILES[&#39;file&#39;]; 
$file_tmp = $file[&#39;tmp_name&#39;]; 
$file_name = $file[&#39;name&#39;]; 
if(is_uploaded_file($file_tmp)){ //确定user有"上传"文件 
$file_ext = strrchr($file_name,&#39;.&#39;); //上传文件的副文件名 
$file_name_new = date(&#39;YmdHis&#39;).$file_ext; 
$host = &#39;127.0.0.1&#39;; 
$port = &#39;21&#39;; 
$user = &#39;admin&#39;; 
$pass = &#39;123456&#39;; 
$link = ftp_connect($host,$port); 
$login = ftp_login($link,$user,$pass); 
ftp_chdir($link,&#39;filedir&#39;); //切换到要放文件的文件夹 
if(ftp_put($link,$file_name_new,$file_tmp,FTP_BINARY)){ 
    $msg = &#39;上传成功&#39;;   
}else{ 
    $msg = &#39;上传失败&#39;; 
} 
}else{ 
    $msg = &#39;上传失败&#39;; 
} 
ftp_close($link); 
echo $msg;
Copy after login
