Using the PHP Function Ftp_Fput

PHP has thousands of built-in functions which are used for different purposes. Functions are code blocks that take input in the form of parameters, process them and return a value. They make the programming code modular and easier to understand. They also allow you to reuse code across scripts.

The ftp_fput function is an inbuilt FTP function that lets you upload files to an FTP server. It takes the following arguments – $ftp_connection, $remote_file_path, $local_file_path, $start_position and $transfer_mode (which can be FTP_ASCII or FTP_BINARY).

Using this, you can transfer files to an ftp-server from your local machine. This can help you bypass firewalls that don’t allow ftp-connections. You need to have a valid username and password to log into the server to be able to do this. You can login into an ftp-server with the help of a function called ftp_login.

To start using this function, first you need to set up an ftp-connection with the help of the ftp_connect function. Then you need to login into that connection with the help of the ftp_login function. Lastly, you need to set the ftp_connection to passive mode using a function called ftp_pasv.

A function is any code that ends with a keyword function and the word function followed by open and closed parenthesis. A function can accept multiple arguments which are listed within its parentheses. During runtime, these variables can be passed to the function and they are executed at the appropriate time.
