ftp_chdir()函数是PHP中的内置函数, 用于更改FTP服务器上的当前目录

语法如下:

ftp_chdir( $ftp_connection, $directory )

参数:此函数接受上述和以下所述的两个参数:

  • $ ftp_connection:它是必填参数。它指定用于执行FTP命令或功能的现有FTP连接。
  • $目录:必填参数。它指定远程服务器中要将当前目录更改到的路径。

返回值:成功返回True, 失败返回False。

注意:

  • 此功能可用于PHP 4.0.0和更高版本。
  • 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, 用户名和密码在某些PHP托管服务器或localhost中运行。
  • 确保你具有更改目录和访问目录的权限。

例子:

<?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!" ;
     } 
}
?>

输出如下:

successfully connected to the ftp server!
logged in successfully!
Current directory successfully changed to htdocs.
Connection closed Successfully!
