以下示例无法在在线IDE上运行。因此，请尝试使用适当的ftp服务器名称在某些PHP托管服务器或localhost中运行。

以下示例说明了PHP中ftp_put()函数的用法：

范例1：

<?php 
   
// Connect to FTP server 
$ftp_server = "localhost"; 
   
// Use correct ftp username 
$ftp_username="user"; 
   
// Use correct ftp password corresponding 
// to the ftp username 
$ftp_userpass="user"; 
   
// File name or path to upload to ftp server 
$file = "filetoupload.txt"; 
    
// Establishing ftp connection  
$ftp_connection = ftp_connect($ftp_server)  
    or die("Could not connect to $ftp_server"); 
   
if( $ftp_connection ) { 
    echo "Successfully connected to the ftp server!"; 
       
    // Logging in to established connection with 
    // ftp username password 
    $login = ftp_login($ftp_connection, $ftp_username, $ftp_userpass); 
       
    // Checking whether logged in successfully or not 
    if($login) { 
        echo "<br>logged in successfully!"; 
           
        if (ftp_put($ftp_connection, 
                "uploadedfile_name_in_server.txt", $file, FTP_ASCII)) 
        { 
          echo "<br>Uploaded successful $file."; 
        } 
        else { 
          echo "<br>Error while uploading $file."; 
        } 
            
    } 
    else { 
        echo "<br>login failed!"; 
    } 
   
    // Closeing the  connection 
    if(ftp_close($ftp_connection)) { 
        echo "<br>Connection closed Successfully!"; 
    }  
} 
?>

输出：

Successfully connected to the ftp server!
logged in successfully!
Uploaded successful filetoupload.txt.
Connection closed Successfully!

范例2：使用端口号21连接到ftp服务器，然后上传文件。

<?php 
  
// Connect to FTP server 
  
// Server name 
$ftp_server = "localhost"; 
  
// Use correct ftp username 
$ftp_username="user"; 
  
// Use correct ftp password corresponding 
// to the ftp username 
$ftp_userpass="user"; 
  
// File name or path to upload to ftp server 
$file = "filetoupload.txt"; 
   
// Establishing ftp connection  
$ftp_connection = ftp_connect($ftp_server, 21)  
    or die("Could not connect to $ftp_server"); 
  
if( $ftp_connection ) { 
    echo "Successfully connected to the ftp server!"; 
      
    // Logging in to established connection with 
    // ftp username password 
    $login = ftp_login($ftp_connection, 
                $ftp_username, $ftp_userpass); 
    if( $login ) { 
          
        // Checking whether logged in successfully or not 
        echo "<br>logged in successfully!"; 
          
        if (ftp_put($ftp_connection,  
            "uploadedfile_name_in_server.txt", $file, FTP_ASCII))  
        { 
          echo "<br>Uploaded successful $file."; 
        } 
        else { 
          echo "<br>Error while uploading $file."; 
        } 
    } 
    else { 
        echo "<br>login failed!"; 
    } 
      
    // Echo ftp_get_option($ftp_connection, 1); 
    // Closeing  connection 
    if(ftp_close($ftp_connection)) { 
        echo "<br>Connection closed Successfully!"; 
    }  
} 
  
?>

输出：

Successfully connected to the ftp server!
logged in successfully!
Uploaded successful filetoupload.txt.
Connection closed Successfully!
