这篇文章主要介绍了php中FTP函数ftp_connect、ftp_login与ftp_chmod用法,详细讲述了PHP的FTP操作技巧,并以实例形式对ftp_connect、ftp_login与ftp_chmod的用法进
本文实例讲述了php中FTP函数ftp_connect、ftp_login与ftp_chmod用法。分享给大家供大家参考。具体方法如下：
ftp_connect() 函数建立一个新的 ftp 连接,若成功,则返回一个连接标识,否则返回 false.
语法:ftp_connect(host,port,timeout),实例代码如下:
复制代码 代码如下:
$file='public_html/index.php'; //定义文件
$conn_id=ftp_connect($ftp_server); //连接到指定的ftp服务器
$login_result=ftp_login($conn_id,$ftp_user_name,$ftp_user_pass); //用指定用户名登录
if(ftp_chmod($conn_id,0644,$file)!==false) //设置文件的模式
{
echo "$file chmoded successfully to 644n"; //输出信息
}
else
{
echo "could not chmod $filen"; //如果设置失败输出信息
}
ftp_close($conn_id); //关闭ftp连接
ftp_chmod() 函数设置 ftp 服务器上指定文件的权限,若成功,则该函数返回新的权限,否则返回 false.
语法:ftp_chmod(ftp_connection,mode,file),代码如下:
复制代码 代码如下:
$ftp_server="ftp.jb51.net"; //定义ftp服务器
$ftp_user="foo"; //定义用户名
$ftp_pass="bar"; //定义用户对应的密码
$conn_id=ftp_connect($ftp_server)or die("couldn't connect to $ftp_server"); //连接到指定ftp服务器
if(@ftp_login($conn_id,$ftp_user,$ftp_pass)) //如果成功登录
{
echo "connected as $ftp_user@$ftp_servern"; //输出相应信息
}
else
{
echo "couldn't connect as $ftp_usern"; //输出不能登录的信息
}
ftp_login() 函数登录 ftp 服务器,若成功则返回 true,失败则返回 false 并发出一个警告.
语法:ftp_login(ftp_connection,username,password)
参数 描述
ftp_connection 必需,规定要使用的 ftp 连接(ftp 连接的标识符).
username 必需,规定用于登录的用户名.
password 必需,规定用于登录的密码.
希望本文所述对大家的PHP程序设计有所帮助。
