php 上传文件到ftp服务器的简单示例单文件

php上传单个文件到ftp服务器的演示范例，感兴趣的小伙伴，下面一起跟随编程之家 jb51.cc的小编来看看吧。
经测试代码如下：

/**
 * 上传文件到ftp服务器
 *
 * @param 
 * @arrange (编程之家) jb51.cc
 **/
// FTP access parameters
$host = 'ftp.example.org';
$usr = 'example_user';
$pwd = 'example_password';
 
// file to move:
$local_file = './example.txt';
$ftp_path = '/data/example.txt';
 
// connect to FTP server (port 21)
$conn_id = ftp_connect($host,21) or die (Cannot connect to host);
 
// send access parameters
ftp_login($conn_id,$usr,$pwd) or die(Cannot login);
 
// turn on passive mode transfers (some servers need this)
// ftp_pasv ($conn_id,true);
 
// perform file upload
$upload = ftp_put($conn_id,$ftp_path,$local_file,FTP_ASCII);
 
// check upload status:
print (!$upload) ? 'Cannot upload' : 'Upload complete';
print \n;
 
/*
** Chmod the file (just as example)
*/
 
// If you are using PHP4 then you need to use this code:
// (because the ftp_chmod command is just available in PHP5+)
if (!function_exists('ftp_chmod')) {
   function ftp_chmod($ftp_stream,$mode,$filename){
        return ftp_site($ftp_stream,sprintf('CHMOD %o %s',$filename));
   }
}
 
// try to chmod the new file to 666 (writeable)
if (ftp_chmod($conn_id,0666,$ftp_path) !== false) {
    print $ftp_path .  chmoded successfully to 666\n;
} else {
    print could not chmod $file\n;
}
 
// close the FTP stream
ftp_close($conn_id);
