Upload file to server via ftp.



<?php

$ftp_server="";

 $ftp_user_name="";

 $ftp_user_pass="";

 $file = "";//tobe uploaded

 $remote_file = "";



 // 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";

    exit;

 } else {

    echo "There was a problem while uploading $file\n";

    exit;

    }

 // close the connection

 ftp_close($conn_id);

?>

For those who dont want to deal with handling the connection once created, here is a simple class that allows you to call any ftp function as if it were an extended method.  It automatically puts the ftp connection into the first argument slot (as all ftp functions require).



This code is php 5.3+



<?php

class ftp{

    public $conn;



    public function __construct($url){

        $this->conn = ftp_connect($url);

    }

    

    public function __call($func,$a){

        if(strstr($func,'ftp_') !== false && function_exists($func)){

            array_unshift($a,$this->conn);

            return call_user_func_array($func,$a);

        }else{

            // replace with your own error handler.

            die("$func is not a valid FTP function");

        }

    }

}



// Example

$ftp = new ftp('ftp.example.com');

$ftp->ftp_login('username','password');

var_dump($ftp->ftp_nlist());

?>

syntax error in the above example, ftp_nlist requires a directory parameter:

$ftp->ftp_nlist('.');   // retrieve contents of current directory

In example 2 above you may need to set the system to to use pasv to get a result ie:

$ftp = new ftp('ftp.example.com'); 
$ftp->ftp_login('username','password'); 
$ftp->ftp_pasv(TRUE);
var_dump($ftp->ftp_nlist());

Think about using the ftp:// wrapper for simple manipulations (getting or storing a single file).

<?php
$content = file_get_contents('ftp://login:password@server/directory/file.txt');
copy('local_file.txt', 'ftp://login:password@server/directory/new_file.txt');
?>

Same kind of mistake: using cURL to get the content of a public URL...
