Definition and Usage
The fpassthru() function reads from the current position in a file - until EOF, and then writes the result to the output buffer.
Note: When using fpassthru() on a binary file on Windows, remember to open the file in binary mode.
Tip: Call rewind() to set the file pointer to the beginning of the file if you have already written to the file.
Tip: To just dump the contents of a file to the output buffer, use the readfile() function instead.
