[PHP] ftp_connect() FTP 連線&上傳範例

Solution1: 
Reference URL. 特別注意 ftp_put上傳兩個變數別弄錯, 說明如下: 
$remote_file
The remote file path. 是目的地端, 也是FTP端的目錄Path. 
$local_file
The local file path. 是程式執行端的本地端,來源檔. 
mode
The transfer mode. Must be either FTP_ASCII or FTP_BINARY.

程式範例-Start
$file = 'somefile.txt';
$remote_file = 'readme.txt';

// set up basic connection
$conn_id = ftp_connect($ftp_server);

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

// upload a file
if (ftp_put($conn_id, $remote_file, $file, FTP_ASCII)) {
 echo "successfully uploaded $file\n";
} else {
 echo "There was a problem while uploading $file\n";
}

// close the connection
ftp_close($conn_id);
程式範例-End

Solution2: 

    /*
    $ftp_server = "ftp.*****.com";
    $ftp_user = "******";
    $ftp_password = "*****";
    */

    $ftp_server = "ftp.gnu.org";
    $ftp_user = "anonymous";
    $ftp_password = "none";


    /* connect */
    $ftp_connection = @ftp_connect($ftp_server);
    if (!$ftp_connection) die('could not connect.');

    /* login */
    $ftp_login = @ftp_login($ftp_connection, $ftp_user, $ftp_password);
    if (!$ftp_login) die('could not login.');

    /* enter passive mode */
    $ftp_passive = @ftp_pasv($ftp_connection, true);
    if (!$ftp_passive) die('could not enable passive mode.');

    /* get listing */
    $ftp_listing = ftp_nlist($ftp_connection, "."); 
    foreach ($ftp_listing as $file){
        echo "

".$file."

";
    }

    ftp_close($ftp_connection);

Solution3: 
function getFtpConnection($uri)
{
    // Split FTP URI into:
    // $match[0] = ftp://username:password@sld.domain.tld/path1/path2/
    // $match[1] = username
    // $match[2] = password
    // $match[3] = sld.domain.tld
    // $match[4] = /path1/path2/
    preg_match("/ftp:\/\/(.*?):(.*?)@(.*?)(\/.*)/i", $uri, $match);

    // Set up a connection
    $conn = ftp_connect($match[3]);

    // Login
    if (ftp_login($conn, $match[1], $match[2]))
    {
        // Change the dir
        ftp_chdir($conn, $match[4]);

        // Return the resource
        return $conn;
    }

    // Or retun null
    return null;
}


Solution4: 

$Ftp_host='000.000.000.000';
$Ftp_port=21;
$Ftp_user='xxxxxx';
$Ftp_pass='aaaaaa';
$Ftp_dir='';
$ftp_link=ftp_connect($Ftp_host,$Ftp_port) or die("No Link");
$login = ftp_login($ftp_link ,$Ftp_user,$Ftp_pass);
ftp_pasv($ftp_link,true);

$alist = ftp_nlist ($ftp_link, "out"); //list out/ 內的所有檔案
while(list($l,$r)=each($alist)){
echo $l.','.$r; //$l=資料序0,1,2... , $r=檔名 out/aaa.xxx
}
@ftp_put($ftp_link, $putFile, $file_Name, FTP_BINARY);    //上傳 $putFile=目地, $file_Name=來源
@ftp_get($ftp_link, $File_Name, $r, FTP_BINARY)    //取回 $File_Name=目地, $r=來源
ftp_delete ($ftp_link,$r); //刪除檔案


Solution5:

// Download a file and store the data in $data
$data = file_get_contents('ftp://username:password@ftp.domain.tld/somefile.txt');

// Loop the contents of the root directory
$dp = opendir('ftp://username:password@ftp.domain.tld/');
while ($file = readdir($dp)) {
  // Do stuff
}
closedir($dp);

// Upload a file
file_put_contents('ftp://username:password@ftp.domain.tld/somefile.txt','This is the file data');

// Upload a file from the local file system
$local = fopen('/path/to/my/file.ext','r');
$remote = fopen('ftp://username:password@ftp.domain.tld/somefile.txt','w');
stream_copy_to_stream($local,$remote);

Other Note: Ref URL.
#1 如需要PHP Create Folder 可以參考如下:

if (!file_exists('path/to/directory')) {
    mkdir('path/to/directory', 0777, true);
}

#2 FTP Create Folder. Ref URL.
// try to create the directory $dirif (ftp_mkdir($conn_id, $dir)) {
 echo "successfully created $dir\n";
} else {
 echo "There was a problem while creating $dir\n";
}

#3,// 確認目前位置
echo "Current directory: " . ftp_pwd($conn_id) . "\n";
