This article summarizes several ways to use the ftp function in PHP to upload files through FTP. Friends who need to learn can refer to it.

The ftp_get() function downloads a file from the FTP server.

Returns true if successful and false if failed.

Grammar
ftp_get(ftp_connection,local,remote,mode,resume)

The ftp_connect() function establishes a new FTP connection.

If successful, return a connection identifier, otherwise return false.

Grammar
ftp_connect(host,port,timeout)

The ftp_login() function logs in to the FTP server.

Returns true if successful, false and issues a warning if failed.

Grammar
ftp_login(ftp_connection,username,password)

The three functions have been introduced, let’s start now.

Example 1

The code is as follows

Copy code

代码如下

复制代码

$ftp_server = "*.*.*.*";
$ftp_user = "lu";
$ftp_pass = "love you";

// set up a connection or die
$conn_id = ftp_connect($ftp_server) or die("Couldn't connect to $ftp_server");

$login_result = ftp_login($conn_id, $ftp_user, $ftp_pass);

if ((!$conn_id) || (!$login_result)) {
        echo "FTP connection has failed!";
        echo "Attempted to connect to $ftp_server for user $ftp_user_name";
        exit;
    } else {
        echo "Connected to $ftp_server, for user $ftp_user_name";
    }

// try to login
$filename=date('Ymd').".xml";
$source_file="/usr/local/IVR/sendwireless/xml/data/".$filename; //源地址
echo $source_file;
$destination_file="/ITC/admin/logstat/ftplog/".$filename; //目标地址
$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY) or die("Couldn't connect to $ftp_server");
ftp_quit($conn_id);

if (!$upload) {
        echo "FTP upload has failed!";
    } else {
        echo "Uploaded $source_file to $ftp_server as $destination_file";
    }
ftp_close($conn_id);

$ftp_server = "*.*.*.*"; $ftp_user = "lu"; $ftp_pass = "love you"; // set up a connection or die $conn_id = ftp_connect($ftp_server) or die("Couldn't connect to $ftp_server"); $login_result = ftp_login($conn_id, $ftp_user, $ftp_pass); if ((!$conn_id) || (!$login_result)) { echo "FTP connection has failed!"; echo "Attempted to connect to $ftp_server for user $ftp_user_name"; exit; } else { echo "Connected to $ftp_server, for user $ftp_user_name"; } // try to login $filename=date('Ymd').".xml"; $source_file="/usr/local/IVR/sendwireless/xml/data/".$filename; //Source address echo $source_file; $destination_file="/ITC/admin/logstat/ftplog/".$filename; //Destination address $upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY) or die("Couldn't connect to $ftp_server"); ftp_quit($conn_id); if (!$upload) { echo "FTP upload has failed!"; } else { echo "Uploaded $source_file to $ftp_server as $destination_file"; } ftp_close($conn_id);

When uploading, first upload the file locally to make necessary modifications, such as adding watermarks, etc., and then upload it to the remote server via FTP.

Example 2:

The code is as follows

Copy code

代码如下

复制代码

//上传图片

if ($_FILES['pic']['name'])
{
$file_path='/opt/www/img/';
$pic = upload('pic', $filename, 'jpg|jpeg|gif|bmp|png', $file_path);
if(!$pic)
{
echo "图片上传失败!";
exit;
}
require_once(ROOT_PATH . 'Lib/Class/Ftp.class.php');
$ftp = new ftp("127.0.0.1","gamezeroftp","123456","/opt/www");
$localfile='/opt/www/img/'.$pic;
$remotefile='/opt/www/gamepics/'.$pic;
$ftpput = $ftp->put($localfile, $remotefile); //FTP上传原图到远程服务器
if(!$ftpput){
echo "上传图片到远程服务器失败!";
}
$ftp->bye(); //关闭FTP连接
}
附上FTP操作类:

ftpUrl=$ftpUrl;
}
if($ftpUser){
$this->ftpUser=$ftpUser;
}
if($ftpPass){
$this->ftpPass=$ftpPass;
}
if($ftpUrl){
$this->ftpDir=$ftpDir;
}
if ($this->ftpR = ftp_connect($this->ftpUrl, 21)) {
if (ftp_login($this->ftpR, $this->ftpUser, $this->ftpPass)) {
if (!empty($this->ftpDir)) {
ftp_chdir($this->ftpR, $this->ftpDir);
}
ftp_pasv($this->ftpR, true);//R 启用被动模式;
$status = 1;
} else {
$status = 3;
}
} else {
$status = 2;
}
}
//R 切换目录;
function cd($dir) {
return ftp_chdir($this->ftpR, $dir);
}
//R 返回当前路劲;
function pwd() {
return ftp_pwd($this->ftpR);
}
//R 创建目录
function mkdir($directory) {
return ftp_mkdir($this->ftpR,$directory);
}
//R 删除目录
function rmdir($directory) {
return ftp_rmdir($this->ftpR,$directory);
}
//R 上传文件;
function put($localFile, $remoteFile = '') {
if ($remoteFile == '') {
$remoteFile = end(explode('/', $localFile));
}
$res = ftp_nb_put($this->ftpR, $remoteFile, $localFile, FTP_BINARY);
while ($res == FTP_MOREDATA) {
$res = ftp_nb_continue($this->ftpR);
}
if ($res == FTP_FINISHED) {
return true;
} elseif ($res == FTP_FAILED) {
return false;
}
}
//R 下载文件;
function get($remoteFile, $localFile = '') {
if ($localFile == '') {
$localFile = end(explode('/', $remoteFile));
}
if (ftp_get($this->ftpR, $localFile, $remoteFile, FTP_BINARY)) {
$flag = true;
} else {
$flag = false;
}
return $flag;
}
//R 文件大小;
function size($file) {
return ftp_size($this->ftpR, $file);
}
//R 文件是否存在;
function isFile($file) {
if ($this->size($file) >= 0) {
return true;
} else {
return false;
}
}
//R 文件时间
function fileTime($file) {
return ftp_mdtm($this->ftpR, $file);
}
//R 删除文件;
function unlink($file) {
return ftp_delete($this->ftpR, $file);
}
function nlist($dir = '/service/resource/') {
return ftp_nlist($this->ftpR, $dir);
}
//R 关闭连接;
function bye() {
return ftp_close($this->ftpR);
}
}
?>

//Upload pictures
if ($_FILES['pic']['name'])

{

echo "Failed to upload pictures to the remote server!"; } $ftp->bye(); //Close FTP connection

}

Attached is the FTP operation class: ftpUrl=$ftpUrl; } if($ftpUser){ $this->ftpUser=$ftpUser; } if($ftpPass){ $this->ftpPass=$ftpPass; } if($ftpUrl){ $this->ftpDir=$ftpDir; } if ($this->ftpR = ftp_connect($this->ftpUrl, 21)) { if (ftp_login($this->ftpR, $this->ftpUser, $this->ftpPass)) { if (!empty($this->ftpDir)) { ftp_chdir($this->ftpR, $this->ftpDir); } ftp_pasv($this->ftpR, true);//R enables passive mode; $status = 1; } else { $status = 3; } } else { $status = 2; } } //R switch directory; function cd($dir) { return ftp_chdir($this->ftpR, $dir); } //R returns the current road strength; function pwd() { return ftp_pwd($this->ftpR); } //R Create directory function mkdir($directory) { return ftp_mkdir($this->ftpR,$directory); } //R Delete directory function rmdir($directory) { return ftp_rmdir($this->ftpR,$directory); } //R Upload file; function put($localFile, $remoteFile = '') { if ($remoteFile == '') { $remoteFile = end(explode('/', $localFile)); } $res = ftp_nb_put($this->ftpR, $remoteFile, $localFile, FTP_BINARY); while ($res == FTP_MOREDATA) { $res = ftp_nb_continue($this->ftpR); } if ($res == FTP_FINISHED) { return true; } elseif ($res == FTP_FAILED) { return false; } } //R download file; function get($remoteFile, $localFile = '') { if ($localFile == '') { $localFile = end(explode('/', $remoteFile)); } if (ftp_get($this->ftpR, $localFile, $remoteFile, FTP_BINARY)) { $flag = true; } else { $flag = false; } return $flag; } //R file size; function size($file) { return ftp_size($this->ftpR, $file); } //Whether the R file exists; function isFile($file) { if ($this->size($file) >= 0) { return true; } else { return false; } } //R file time function fileTime($file) { return ftp_mdtm($this->ftpR, $file); } //R delete file; function unlink($file) { return ftp_delete($this->ftpR, $file); } function nlist($dir = '/service/resource/') { return ftp_nlist($this->ftpR, $dir); } //R close the connection; function bye() { return ftp_close($this->ftpR); } } ?>
