< p >PHP FTP 管理是指使用 PHP 語言實(shí)現(xiàn)對(duì) FTP 服務(wù)器上的文件進(jìn)行管理操作。通過 PHP 的 FTP 函數(shù)，可輕松的連接到 FTP 服務(wù)器，實(shí)現(xiàn)目錄列表、上傳、下載、刪除等常見 FTP 操作。下面我們就來看一些 PHP FTP 管理的實(shí)例。< /p >< p >目錄列表操作是指展示 FTP 服務(wù)器上的文件和目錄列表。代碼示例如下：< /p >< pre >$ftp_server = "ftp.example.com"; $ftp_username = "username"; $ftp_userpass = "password"; $ftp_conn = ftp_connect($ftp_server) or die("Could not connect to $ftp_server"); $login = ftp_login($ftp_conn, $ftp_username, $ftp_userpass); $contents = ftp_nlist($ftp_conn, "public_html"); //展示 public_html 目錄中的文件和目錄列表 foreach ($contents as $file) { echo "$file\n"; } ftp_close($ftp_conn);< /pre >< p >上傳操作是指將本地的文件上傳到 FTP 服務(wù)器上。代碼示例如下：< /p >< pre >$ftp_server = "ftp.example.com"; $ftp_username = "username"; $ftp_userpass = "password"; $ftp_conn = ftp_connect($ftp_server) or die("Could not connect to $ftp_server"); $login = ftp_login($ftp_conn, $ftp_username, $ftp_userpass); $file = "test.txt"; $remote_file = "/public_html/test.txt"; if (ftp_put($ftp_conn, $remote_file, $file, FTP_BINARY)) { echo "$file has been uploaded successfully\n"; } else { echo "There was a problem while uploading $file\n"; } ftp_close($ftp_conn);< /pre >< p >下載操作是指將 FTP 服務(wù)器上的文件下載到本地。代碼示例如下：< /p >< pre >$ftp_server = "ftp.example.com"; $ftp_username = "username"; $ftp_userpass = "password"; $ftp_conn = ftp_connect($ftp_server) or die("Could not connect to $ftp_server"); $login = ftp_login($ftp_conn, $ftp_username, $ftp_userpass); $remote_file = "/public_html/test.txt"; $file = "test.txt"; if (ftp_get($ftp_conn, $file, $remote_file, FTP_BINARY)) { echo "$remote_file has been downloaded successfully\n"; } else { echo "There was a problem while downloading $remote_file\n"; } ftp_close($ftp_conn);< /pre >< p >刪除操作是指將 FTP 服務(wù)器上的文件刪除。代碼示例如下：< /p >< pre >$ftp_server = "ftp.example.com"; $ftp_username = "username"; $ftp_userpass = "password"; $ftp_conn = ftp_connect($ftp_server) or die("Could not connect to $ftp_server"); $login = ftp_login($ftp_conn, $ftp_username, $ftp_userpass); $file = "/public_html/test.txt"; if (ftp_delete($ftp_conn, $file)) { echo "$file has been deleted successfully\n"; } else { echo "There was a problem while deleting $file\n"; } ftp_close($ftp_conn);< /pre >< p >通過上述例子可知，PHP FTP 管理操作是非常簡(jiǎn)單易用的。需要注意的是，在使用 PHP FTP 函數(shù)時(shí)，需要確保服務(wù)器的 FTP 擴(kuò)展已經(jīng)安裝并啟用，以便正常執(zhí)行 FTP 操作。< /p >
