本文实例讲述了php中ftp_chdir与ftp_cdup函数用法。分享给大家供大家参考。具体用法如下:

ftp_chdir()函数

若成功,则返回 true,否则返回 false,如果切换目录失败,php还会发出一条警告.

语法:ftp_chdir(ftp_connection,directory)

参数 描述
ftp_connection 必需,规定要使用的 ftp 连接,ftp 连接的标识符.
directory 必需,规定要切换到的目录.

复制代码 代码如下:
//设置基础连接
$conn_id=ftp_connect($ftp_server);
//用指定用户名密码登录到ftp服务器
$login_result=ftp_login($conn_id,$ftp_user_name,$ftp_user_pass);
//检查连接是否成功
if((!$conn_id)||(!$login_result))
{
  die("ftp connection has failed !");
}
echo "current directory:", ftp_pwd($conn_id),"n";
//执行切换目录操作
if(@ftp_chdir($conn_id,"somedir"))
{
  echo "current directory is now:", ftp_pwd($conn_id),"n";
}
else
{
  echo "couldn't change directoryn";
}
ftp_cdup($dir);         //执行切换目录操作
/*
ftp_cdup() 函数把当前目录改变为 ftp 服务器上的父目录。
//若成功,则返回 true。否则返回 false。
//语法
ftp_cdup(ftp_connection)

希望本文所述对大家的PHP程序设计有所帮助。
