This is an example of how to allow fopen() to overwrite a file on an FTP site. If the stream context is not modified, an error will occur: "...failed to open stream: Remote file already exists and overwrite context option not specified...".<?php// The path to the FTP file, including login arguments$ftp_path = 'ftp://username:password@example.com/example.txt';// Allows overwriting of existing files on the remote FTP server$stream_options = array('ftp' => array('overwrite' => true));// Creates a stream context resource with the defined options$stream_context = stream_context_create($stream_options);// Opens the file for writing and truncates it to zero length if ($fh = fopen($ftp_path, 'w', 0, $stream_context)){ // Writes contents to the file fputs($fh, 'example contents'); // Closes the file handle fclose($fh);}else{ die('Could not open file.');}?>
