PHP ftp_chdir()用法及代碼示例


ftp_chdir()函數是PHP中的內置函數,用於更改FTP服務器上的當前目錄。

用法:

ftp_chdir( $ftp_connection, $directory )

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。
  • $directory:必填參數。它指定遠程服務器中要將當前目錄更改到的路徑。

返回值:成功返回True,失敗返回False。

注意:

  • 此函數可用於PHP 4.0.0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。
  • 確保您具有更改目錄和訪問目錄的權限。

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"; 
   
// 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_chdir() changing current directory to "htdocs" 
        // remember, you must have folder that will use inside 
        // current directory of ftp server.  
        // Here htdocs folder exists in ftp server inside 
        // base or root directory 
        if (ftp_chdir($ftp_connection, "htdocs")) { 
            echo "<br>Current directory successfully changed to htdocs."; 
        } 
        else { 
            echo "<br>Error while changing current directory."; 
        } 
    } 
    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!
Current directory successfully changed to htdocs.
Connection closed Successfully!
