PHP ftp_exec()用法及代碼示例

ftp_exec()函數是PHP中的內置函數,用於在FTP服務器上執行命令。

用法:

ftp_exec( $ftp_connection, $command )

參數:該函數接受上述和以下描述的兩個參數:


  • $ftp_connection:它是必填參數。它指定用於執行FTP命令或函數的現有FTP連接。
  • $command:它是必填參數。它指定要在成功建立連接的FTP服務器上執行的命令。

返回值:成功返回True,失敗返回False。

注意:

  • 此函數可用於PHP 4.0.3和更高版本。
  • 以下示例無法在在線IDE上運行。因此,請嘗試使用適當的ftp服務器名稱,用戶名和密碼在某些PHP托管服務器或localhost中運行。

例:

<?php 
  
// Connect to FTP server 
// Use a correct ftp server 
$ftp_server = "localhost"; 
  
// Use correct ftp username 
$ftp_username="username"; 
  
// Use correct ftp password corresponding 
// to the ftp username 
$ftp_userpass="password"; 
  
// Command to be executed on FTP server 
$command="ls-al > test.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); 
      
    if( $login ) { 
          
        // Checking whether logged in successfully or not 
        echo "<br>logged in successfully!"; 
          
        // ftp_exec() executes the command  
        if (ftp_exec($ftp_connection, $command)) { 
            echo "<br>".$command." has been successfully executed."; 
        } 
        else { 
            echo "<br>Error while executing the command ."; 
        } 
    } 
    else { 
        echo "<br>login failed!"; 
    } 
      
    // Closeing  connection 
    if(ftp_close($ftp_connection)) { 
        echo "<br>Connection closed Successfully!"; 
    }  
} 
?>

輸出:

successfully connected to the ftp server!
logged in successfully!
ls-al > test.txt has been successfully executed.
Connection closed Successfully!
