在php中我們可以利用ftp_connect相關函數實現文件上傳與下載功能,其實就是ftp客戶端一樣的操作,下面我來給大家介紹如何利用php來實現

大概原理

遍歷項目中的所有非排除文件，然后獲取文件修改時間晚于文件上一次修改時間的文件

然后將這些文件，通過ftp上傳到對應的目錄

具體代碼如下:

因為只是工具，代碼很亂，見諒

<?php

error_reporting(7);

if ($_SERVER['SERVER_ADDR'])exit;//禁止在web服務器下運行

$_GET['exclude'] = array('number.txt','uploads','Zend','docs','cache','You','managesdk'); //排除上傳目錄,定義為全局變量

$fileobj = new FilerFile();

$path = "/data/longtu/"; //項目目錄的根目錄

$files = $fileobj->Zip($path); //過濾出最新的修改文件

$path = str_replace("/data/longtu/","",$path);

$config = array(

'hostname' => 'xxx.xxx.xx.xxx', //ftp服務器地址

'username' => 'xxx', //ftp用戶

'password' => '?xxxxxxxxxxx', //ftp密碼

'port' => 21 //端口

);

$ftp = new Ftp();

$ftp->connect($config); //鏈接服務器

//$a=$ftp->filelist();

$LOCAL_ROOT = realpath(dirname(__DIR__)."/../../");

chdir($LOCAL_ROOT);

foreach ($files as $k=>$v){

$f = $path.$v;

$tmp = $ftp->upload($f, $f);

if($tmp){

echo "upload $f -> success /n";

}

}

//$ftp->download('ftp_upload.log','ftp_download.log');

//

//$ftp->upload('ftp_err.log','ftp_upload.log');

//$ftp->download('ftp_upload.log','ftp_download.log');

/*

*

* $dir = "/test";

if(@ftp_chdir($conn, $dir))

判斷是否為文件夾
