Tips and Comments
Tip:If you have already written data to the file, you must call rewind() to move the file pointer to the beginning of the file.
Tip:If you do not modify the file and do not retrieve at a specific location, but just want to download the content of the file to the output buffer, you should use readfile(), so that the fopen() call can be omitted.
Comment:When using fpassthru() for binary files on Windows systems, make sure to add b in the mode when opening the file with fopen() to open the file in binary mode. Encourage the use of the b flag when handling binary files, even if the system does not need it, as this can make the script more portable.
Example

<?php
$file = fopen("test.txt","r");

fgets($file);
// Send the rest of the file to the output cache
