How can I transfer the contents of a file from a local Windows or Linux directory to a PHP server?

To transfer the contents of a file from a local Windows or Linux directory to a PHP server, you can use the move_uploaded_file() function in PHP. First, upload the file from the local directory to a temporary location on the server using move_uploaded_file(). Then, move the file from the temporary location to the desired directory on the server.

<?php
$localFilePath = 'path/to/local/file.txt';
$serverFilePath = 'path/to/server/directory/file.txt';

if (move_uploaded_file($localFilePath, $serverFilePath)) {
    echo 'File transferred successfully.';
} else {
    echo 'Error transferring file.';
}
?>
