ftp_size - PHP code example

The PHP Function Ftp_Size

The php function ftp_size is used to retrieve the size of a file on an ftp server. It returns the file size in bytes on success or -1 on error.

ftp_size is one of the many FTP functions available in PHP. These functions give you access to the FTP protocol which enables you to open, login and close connections as well as upload, download, rename, delete and get information on files on file servers. They require that you compile PHP with --enable-ftp.

FTP files have a different structure than those in the local filesystem and are often accessed via the command line. Hence, it is important to know how to use these functions correctly in order not to lose data.

The ftp_size() function takes two parameters - ftp_stream and remote_file. ftp_stream is the connection identifier returned by the ftp_connect() function, while remote_file is the name of the file you want to retrieve the size of.

The ftp_size() function is an excellent tool for retrieving the size of files on an ftp server. With proper usage and error handling, it can be an invaluable asset in your PHP projects.
