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!
